Centris Fabricius, 1804 is a genus of solitary bees widely distributed in America (Moure et al., 2007Moure, J. S.; Melo, G. A. R. & Vivallo, F. 2007. Centridini Cockerell & Cockerell. In: Moure, J. S.; Urban, D. & Melo, G. A. R. orgs. Catalogue of Bees (Hymenoptera, Apoidea) in the Neotropical Region. Curitiba, Sociedade Brasileira de Entomologia, p. 83-142.). Along with its wide distribution on the continent, it is also one of those with the highest specific richness (Vivallo, 2020Vivallo, F. 2020j. The oil-collecting bees of Centris (Paracentris) (Hymenoptera: Apidae) Taxonomy-Biodiversity-Distribution. Rio de Janeiro, Editora Publ!t. 376p.j, 2022Vivallo, F. 2022. The oil-collecting bees of Centris (Melanocentris) (Hymenoptera: Apidae). Rio de Janeiro, Author’s edition, xix+ 514p.). This great diversity contributed to a profuse, extensive and sometimes complex taxonomic history, which is evidenced by the large number of species described, the number of which are considered valid, and the many synonyms that have been proposed in the last 200 years.

Recently, a series of extensive and complete articles on the taxonomy of Centris have been published (Vivallo, 2018Vivallo, F. 2018. Taxonomic note on the type species of Centris (Melanocentris).

Rio de Janeiro, Author’s edition, xix+ 514p.), which have contributed to taxonomic stability mainly at specific level. Those papers have also allowed elucidating the real identity of some taxa, as well as recognizing and subsequently describing new species that until now remained unknown to science. The most recent example can be found in the taxonomic revision of the subgenus C. (Melanocentris) Friese, 1901 (Vivallo, 2022Vivallo, F. 2022. The oil-collecting bees of Centris (Melanocentris) (Hymenoptera: Apidae). Rio de Janeiro, Author’s edition, xix+ 514p.), where numerous new species were described, for example C. velutina Vivallo, 2022 from Venezuela, C. vulnicura Vivallo, 2022 from Brazil, and C. caliginosa Vivallo, 2022 from Peru.

Continuing with the taxonomic study of the species of Centris, in this article the primary types of the species described by the entomologists from the Americas: Alpheus Packard, Arturo Roig-Alsina, Charles Michener, Flamínio Ruiz, Haroldo Toro, James Crawford, Jesus Santiago Moure, Philip Timberlake, and Roy Snelling are studied. All these authors were specialists in other insect groups, making circumstantial inputs in Centris, except for Snelling and Moure who, among them, made the largest number of contributions in the genus.

MATERIAL AND METHODS

All labels are here considered whitish and rectangular, and the data contained on them is black, handwritten or printed. The specific features of the labels, like coloration or type of writing are given in squared brackets ([ ]). Some information on the handwritten labels is difficult to decipher, in these cases the symbol ‘[?]’ was used. The backward slash (\) indicates different labels on the pin of the same specimen. All data contained on the labels was transcribed verbatim. The specimens cited are housed in the following collections: American Museum of Natural History, New York, United States (AMNH); California Academy of Sciences, San Francisco, United States (CAS); Colegio San Pedro Nolasco, Santiago, Chile (CSPN); Central Texas Melittological Institute, Austin, United States (CTMI); Coleção Entomológica Pe.

RESULTS

Recognition of the type specimens. The primary types of the species studied here were recognized following the information indicated in their respective original descriptions, about the place of deposit as well as the data on the labels of the specimens. Both pieces of information were contrasted in order to verify the existence of inconsistencies that could interfere with the recognition of the primary types.

In general, the types were indeed found in the institution indicated in each description. However, in some specific cases, apparently the specimens were not sent to the institution mentioned, despite what was indicated in the original description.

Alpheus Packard. Alpheus Spring Packard Jr. (1839-1905) was an American entomologist, naturalist and paleontologist. He worked as professor of Zoology at Brown University and during his years of activity he described over 500 new species, especially butterflies and moths (Cockerell, 1920Cockerell, T. D. A. 1920. Biographical memoir of Alpheus Spring Packard 1839‒1905. Biographical Memoirs. National Academy of Sciences of the United States of America 9:179-236. ). Packard began to work at the Museum of Comparative Zoology under the direction of the Swiss biologist and geologist Jean Louis Rodolphe Agassiz (1807‒1873) but during his stay at that institution he had some differences with the staff and he leaved the Museum (Mead, 1918Mead, A. D. 1918. Alpheus Spring Packard (1839‒1905). Proceedings of the American Academy of Arts and Sciences 53(10):848-850.). In 1867, Packard was appointed as one of the curators of the Peabody Academy of Science at Salem, Massachusetts, United States. During his stay at this institution, he published several new species to science, including three of them in Centris. Packard passed away on 14 February 1905 in Providence, Rhode Island, United States, aged 65.

Packard’s Centris bees. The three species of Centris described by Packard were based on specimens collected by the American naturalist James Orton (1830‒1877) during the Smithsonian Expedition to South America in 1867. Most species described in that article were based on specimens collected on the route from Quito across the Andes, down the Napo River, and along the Maranon River. However, Packard (1869) mentioned that the Brazilian exemplars were collected in the upper Amazon, namely, the Maranon River and its tributary the Napo River. These both are Peruvian effluents of the Amazon River but their extensions do not reach the Brazilian territory. In the descriptions of the species of Centris proposed by him, he mentioned that they were collected on the “route along the Napo and Maranon Rivers”. That information was effectively cited on the labels of those specimens, however, below it appears “Brazil”, being this a conflicting data.

Packard mentioned that almost all species described in his article were based on single specimens which is somewhat reinforced in each description, because he mentioned specimen in singular. Thus, it was assumed that they were based on holotypes. In the case of C. quadrimaculata Packard, 1869 and C. conica (Packard, 1869) it seems to be true, but not in C. braccata Packard, 1869. Despite he mentioned that the description was based on a female, two specimens of that sex were found at MCZ.

Arturo Roig-Alsina. Arturo Hernán Roig-Alsina is an Argentinean entomologist, curator of the insect collection of the MACN. Most of his research is focused on solitary and cleptoparasitic bees, but he also had published several articles on wasps, as well as in other groups of arthropods.

Roig-Alsina’s Centris bees. Despite his prolific research activity and the large number of published articles, so far Roig-Alsina has only published a single paper on Centris (Roig-Alsina, 2000). In the revision of the species of the genus that occur in Argentina, he included the description of six new species, mainly from the north of the country.

Charles Michener. Charles Duncan Michener (1918-2015) was an American entomologist and the most important melittologist of the world. Greatly influenced by his parents, Michener admired the nature (Engel, 2016aEngel, M. S. 2016a. Charles D. Michener (1918-2015): The compleat Melittologist. Journal of the Kansas Entomological Society 89(1):1-44.). During his adolescence he started studying some of the insects he collected in California with his family, making draws and keys that would later appear in his dissertation and seminal monograph on the comparative morphology of bees (Michener, 1944Michener, C. D. 1944. Comparative external morphology, phylogeny, and a classification of the bees. Bulletin of the American Museum of Natural History 82:151-326.). Michener admired one of the most proliferous naturalists of his time, Theodore Dru Alison Cockerell (1866‒1948) and in 1932, he wrote him asking for help with the identification of some bees (Engel, 2016aEngel, M. S. 2016a. Charles D. Michener (1918-2015): The compleat Melittologist. Journal of the Kansas Entomological Society 89(1):1-44.). Cockerell responded enthusiastically to the young teenager encourage him to obtain literature to increase his knowledge on that group of insects (Engel, 2016aEngel, M. S. 2016a. Charles D. Michener (1918-2015): The compleat Melittologist. Journal of the Kansas Entomological Society 89(1):1-44.). Michener kept building his collection and his knowledge on several species of bees and promptly he was able to publish his first article on nest of Dianthidium singulare perluteum Cockerell, 1904 [= Dianthidium singulare (Cresson, 1879)] which also included supplemental remarks on the morphology of the male of the subspecies (Michener, 1935Michener, C. D. 1935. A note on Dianthidium singulare perluteum T. & W. Ckll. Pan-Pacific Entomologist 11(1):23-24.). Cockerell invited Michener to spend the summer at his home in Colorado after the latter’s junior year in high school. A year later he enrolled at the University of Colorado, Berkeley, graduating with his Bachelor of Science in 1939 and a Ph.D. two years later in December of 1941 (Engel, 2016bEngel, M. S. 2016b. In Memoriam: Charles Duncan Michener (1918-2015). Transactions of the Kansas Academy of Science 119(1):109-112.). His dissertation was a comprehensive treatment of bee morphology, as well as a revised classification and evolutionary scheme for the group worldwide, although with a particular focus on the identification of the North American fauna (Engel, 2016bEngel, M. S. 2016b. In Memoriam: Charles Duncan Michener (1918-2015). Transactions of the Kansas Academy of Science 119(1):109-112.). That work was published in 1944 and it revolutionized the study of wild bees, providing the first truly stable system from which to further explore their diversity and evolution (Engel, 2016bEngel, M. S. 2016b. In Memoriam: Charles Duncan Michener (1918-2015). Transactions of the Kansas Academy of Science 119(1):109-112.).

The comprehensive knowledge on bee systematics that Michener had during his years of activity was unmatched. During his life a further 91 species and six genera/ subgenera would come to bear his name (Engel, 2016aEngel, M. S. 2016a. Charles D. Michener (1918-2015): The compleat Melittologist. Journal of the Kansas Entomological Society 89(1):1-44.). His knowledge was divulged through many scientific articles and books, but also among his students. Some years after his retirement of the University of Kansas where he worked most of his life (Engel, 2016bEngel, M. S. 2016b. In Memoriam: Charles Duncan Michener (1918-2015). Transactions of the Kansas Academy of Science 119(1):109-112.), he published the first edition of his monumental work “The Bees of the World”. The classificatory system proposed in that book was widely accepted by the melittological society and became the start point of taxonomic and phylogenetic analyses performed by students and researchers around the world. Michener passed away in Lawrence, Kansas, in 2015, aged 97.

Michener’s Centris bee. As previously mentioned, Michener was a leading expert on bees. He made countless contributions on bionomy, morphology, taxonomy and systematics at different levels of the classification of that group of insects. However, he made a relatively few number of articles citing species of Centris and in only one of them he proposed a new species from Central America.

Flamínio Ruiz. Serapio Flamínio Ruiz Pereira was a Chilean priest and entomologist (1883-1942). He spent his youth in Bulnes (Ñuble Province, southern Chile), his natal city, entering in the Army in 1909, when he joined the Mercedary Order (Ureta, 1957Ureta E. R. 1957. El Hno. Flamínio Ruiz Pereira. Museo Nacional de Historia Natural, Noticiario Mensual 16:1.). Ruiz was fascinated by nature and due this interest he was translated to Santiago (Metropolitan Region) where he was teacher of Biology and Natural Sciences at Colegio San Pedro Nolasco (CSPN) for almost three decades (Ureta, 1957Ureta E. R. 1957. El Hno. Flamínio Ruiz Pereira. Museo Nacional de Historia Natural, Noticiario Mensual 16:1.). In that institution he funded a museum where he deposited the specimens that he collected in nature. The main collection of the museum was of insects, turning the Chilean bees his favorite group.

Among the articles written by Ruiz, stand out the first and second parts of “Apidología Chilena”, published in 1940Ruiz, F. 1940. Apidología Chilena. I Parte. Revista Chilena de Historia Natural 44:282-377. and 1942, respectively. In those articles he studied partially the families Colletidae, Megachilidae and Anthophoridae (= Apidae). The families Halictidae and Andrenidae were never studied by him as well as most of the melittofauna from northern Chile, apparently due he did not have the chance to know (Toro, 1986Toro, H. 1986. Lista preliminar de los ápidos chilenos. Acta Entomológica Chilena 13:121-132.). Ruiz passed away in Santiago, on 8 November 1942, aged 59.

Ruiz’s Centris bee. Ruiz proposed about fifteen new species and varieties of Chilean bees, among them, C. nigerrima var. orellanai Ruiz, 1940. This supposed variety of C. nigerrima (Spinola, 1851) was described based on females collected by the agricultural engineer Baldomero Orellana (1892‒ ?), former Director of the Escuela Práctica de Agricultura of Santiago in Los Pelambres, an open pit copper mine located at 3,600 m.a.s.l. in the mountains of the Coquimbo Region, northern Chile. The male identified by Ruiz as belonging to this variety was collected in Punta de Lobos, O’Higgins Region, southern Chile at sea level. That specimen was actually a male of C. nigerrima and this explains the supposed relationship between that species with the variety proposed by him.

Centris orellanai Ruiz, 1940Ruiz, F. 1940. Apidología Chilena. I Parte. Revista Chilena de Historia Natural 44:282-377.

Centris nigerrima var. orellanaiRuiz, 1940Ruiz, F. 1940. Apidología Chilena. I Parte. Revista Chilena de Historia Natural 44:282-377.: 335.

Type data. The holotype female of this supposed variety was originally housed at CSPN and according to José Salamanca, current curator of the museum most likely it was destroyed, as well as much of Ruiz’s collection. Based on that information, Vivallo (2013Vivallo, F. 2013. Revision of the bee subgenus Centris (Wagenknechtia) Moure, 1950 (Hymenoptera: Apidae: Centridini). Zootaxa 3683:501-537.) designated a neotype, providing a redescription based on it. In 2017, during a visit to the bee collection of the AMNH I found a female, mixed with other specimens that match exactly with the information provided by Ruiz in the description of C. orellanai. I am interpreting that female as the true type specimen of C. nigerrima var. orellanai, being here recognized as such. The specimen is in good condition and it has the following data label: [white label with blue rimmed margin] Coll ORELLANA [printed in blue] Pelambres. 16 [handwritten] .93. [printed in blue] I 5 [handwritten] CHILE [printed in blue]\ Centris orellanai Ruiz, 1941 [printed]\ [yellow label] PARATIPO [printed]\ [light blue label] HOLOTYPE Centris nigerrima var. orellanai Ruiz, 1940 F. Vivallo lab, 2017 [handwritten] (AMNH).

Ruiz mentioned three females and one male but it is not clear if the specimen he chose as holotype had the same information label of the other two females. If the three females shared the same information, then the specimen housed at AMNH could be interpreted as a syntype and not as the holotype of the species. Considering this, along with the unknown whereabouts of the other two females, seems correct, at least until one of the other two missing females is found, to recognize that female as holotype avoiding the designation of a lectotype. Independently of the option chosen, that female belongs to the type series of the species.

It is not clear how and when that female was sent to the AMNH. A possibility could be when Haroldo Toro sent a large number of specimens to the AMNH, because the female bears a yellow label of paratype that Toro used to put in his specimens.

Type locality. Chile: Coquimbo Region: Los Pelambres.

Haroldo Toro. Haroldo Enrique Toro Gutiérrez was a Chilean entomologist (1934-2002). From his youth, he was interested in teaching, maybe influenced by his mother, a teacher of a school in Chillán, southern Chile (Chiappa, 2003Chiappa, E. 2003. Obituario Haroldo toro G. (1934‒2002). Revista Chilena de Entomología 29:117-124.). Toro was a brilliant student of biology and chemical and due his talent and capacities he was incorporated as Professor at the Pontificia Universidad Católica de Valparaíso, Chile (PUCV). In that institution Toro created the Laboratory of Zoology and teach classes of Zoology and Entomology. In this later area, he made his most important contributions, mainly focused on taxonomy, systematics and bionomy of Chilean bees. He described 144 species, in Andrenidae, Colletidae, Halictidae, Megachilidae and Apidae. Toro is still recognized internationally as the most important Chilean melittologist and I am sure that all his students were proud to have had the opportunity to meet him during their professional training and to have attended one of his classes. Haroldo Toro passed away in Valparaíso, aged 67.

Elizabeth Chiappa. Originally linked to pedagogy in Biology, Elizabeth Chiappa Tapia (1941‒ 2022), was an academic of the Facultad de Ciencias Naturales y Exactas of the Universidad de Playa Ancha (UPLA), Valparaíso, Chile. From there, she developed an extensive research career related to the reproductive behavior of bees and wasps from Chile. She was formed by Haroldo Toro who introduced her to the world of insects. In a short time, she moved away from taxonomy and concentrated her studies on ethology, the area where she focused most of her research. Elizabeth Chiappa passed away during the development of this article in Viña del Mar, Chile, aged 81.

Toro & Chiappa’s Centris bees. During the decades of 1960 and 1980 Toro and his colleagues at the Department of Zoology of the PUCV made several collecting trips to northern Chile, mainly to the Atacama Desert. In those trips were collected biological samples of diverse groups of organisms which were used in the disciplines of Zoology for graduate and undergraduate students. During those trips to La Tirana and Pica in the Tarapacá Region there were collected the specimens used by Toro and Chiappa to describe a new species and subspecies of Centris. The holotypes of both taxa are currently housed at AMNH.

Type data. The specimen designated holotype is a male collected in La Tirana, northern Chile, by the Chilean ichthyologist Eduardo De la Hoz Urrejola (1941‒1997), who was member of the Department of Zoology of the PUCV and former student of Haroldo Toro. The holotype was originally housed at PUCV, but is currently in the AMNH. It bears the following data label: TARAPACA TIRANA 15-IX-84 [printed]\ DE LA HOZ COL.

In 1970, De la HozDe la Hoz, E. 1970. Estudio de variación de genitalia en Centris (Hym. Apoidea). Anales del Museo de Historia Natural de Valparaíso 3:129-134. published an article on the intraspecific variation of the male genitalia in three species of Centris using some specimens identified as C. mixta Friese, 1904 collected during the expeditions of the PUCV to northern Chile. Centris mixta tamarugalis was described 29 years after De la Hoz’s paper and at that time the subspecies was not considered different from C. mixta. This means that the research conducted by him was actually based on specimens of C. tamarugalis and not of the former species (Vivallo et al., 2003Vivallo, F.; Zanella, F. C. V. & Toro, H. 2003.

James Crawford. James Chamberlain Crawford (1880-1950) was an American entomologist. For many years Crawford was an active member of the Entomological Society of Washington, acting as recording secretary and member of its editorial committee (Gahan et al., 1951Gahan, A. B.; Russell, L. M. & Heinrich, C. H. 1951. Obituary: James Chamberlain Crawford 1880-1950. Proceedings of the Entomological Society of Washington 53:107-109.). In 1904, he joined the Bureau of Entomology as special field agent, studying the cotton insects in Texas, United States. While in that city, Crawford published a number of papers focused on taxonomy of Hymenoptera. Some years later he was brought to Washington and appointed as curator of the Division of Insects in the United States National Museum staying in that institution until 1917. During that time, he specialized in the taxonomy of hymenopteran insects publishing numerous papers in different journals and magazines. He passed away in Bethesda, Maryland, United States, aged 70.

Crawford’s Centris bees. In Centris Crawford described one species and one variety from Central America, based on specimens collected in Costa Rica. The contribution made by this author was failed, because both taxa are currently considered junior synonyms. He also failed in mentioning which specimens were the holotypes or citing any additional data to recognize them. In the type series of both taxa found at NMNH there is a single specimen of each series labeled as “Type”, while the others bear a label of “cotype”. This procedure is found in the species of Centris bees described by Cockerell (see Vivallo, 2020Vivallo, F. 2020j. The oil-collecting bees of Centris (Paracentris) (Hymenoptera: Apidae) Taxonomy-Biodiversity-Distribution. Rio de Janeiro, Editora Publ!t. 376p.c) and whose primary types are also deposited in NMNH. Considering this, I am interpreting that Crawford made both descriptions based on single specimens, therefore, holotypes.

A third specimen that apparently belongs to the type series was also found at NMNH. This female bears a red label with the word “cotype”. However, it was collected on 13th and not on 15th as explicitly cited by Crawford. Considering this fact, there are two possibilities: it could be recognized as a non-member of the type series or, as a true member but with its collecting date erroneously cited in the article.

Jesus Santiago Moure. Jesus Santiago Moure (1912‒2010) was a Brazilian religious trained in philosophy, natural sciences, physics, and mathematics (Urban & Melo, 2010Urban, D. & Melo, G. A. R. 2010. Obituary: Jesus Santiago Moure. Revista Brasileira de Entomologia 54(3):515-518.). Always an admirer of nature, he was interested in insects during his youth, beginning his studies in beetles and later in bees, being the latter group where he spent much of his professional career (Silva, 1992Silva, J. L. 1992. Padre Jesus Santiago Moure - 80 anos. Revista Brasileira de Zoologia 9(1-2).). Moure was one of the most important melittologists of the 20th century, publishing more than 220 articles mainly focused on bees from the Neotropical region. He described 484 species and 218 genera, most of which are currently considered valid (Urban & Melo, 2010Urban, D. & Melo, G. A. R. 2010. Obituary: Jesus Santiago Moure. Revista Brasileira de Entomologia 54(3):515-518.). Moure passed away in Batatais, Brazil, aged 97.

Moure’s Centris bees. Moure contributed actively on the taxonomy of Centris bees. He described 25 species, 21 of them currently considered valid, and he is the main author of the subgeneric arrangement of the genus (see Moure, 1945Moure, J. S. 1945. Apoidea da Coleção do Conde Amadeu Barbiellini. II. (Hym. Apoidea). Revista de Entomologia 16(3):394-414., 1950Moure, J. S. 1950. Alguns agrupamentos novos de abelhas neotropicais. Dusenia 1(6):385-396.). Moure resolved several taxonomic problems about the identity of some species, mainly those described by European entomologists, like Giovanni Gribodo (Moure, 1960aMoure, J. S. 1960a. Abelhas da Região Neotropical descritas por G. Gribodo (Hymenoptera: Apoidea). Boletim da Universidade do Paraná Zoologia 1:1-18.), Johan Christian Fabricius (Moure, 1960bMoure, J. S. 1960b. Notes on the types of the Neotropical bees described by Fabricius (Hymenoptera: Apoidea). Studia Entomologica 3(1/4):97-160.) and Maximilian Perty (Moure, 1960cMoure, J. S. 1960c. Notas sôbre os tipos de abelhas do Brasil descritas por Perty em 1833 (Hymenoptera-Apoidea). Boletim da Universidade do Paraná, Zoologia 6:1-23.). He had a special attraction to Centris bees, mainly by the beauty of its species, and several times he expressed it saying that it was one of his favorite groups of bees, along with stingless and orchid bees.

Moure’s colleagues. Carlos Alberto Campos Seabra (1916‒2001) was a Brazilian doctor, entomology enthusiast and friend of Moure for several years. Seabra had a private collection of more than two million insects, mainly Coleoptera and Hymenoptera, his favorite group. He transferred his collection to the MNRJ with the assistance of his colleague and friend the Uruguayan coleopterist specialist in longhorn beetles Miguel Ángel Monné (1938‒ ). In Centris Moure and Seabra described together six species.

Favízia Freitas de Oliveira is a Brazilian melittologist specialist in stingless bees, and Blandina Felipe Viana is a Brazilian ecologist specialist in pollination. With them, Moure described a new species of Centris.

Marina Siqueira de Castro is a Brazilian biologist, specialist in ecology applied to environmental management. With her, Moure described a single new species of Centris.

Type data. This species was described based on two females collected in Venezuela and Brazil. The holotype was collected by the German entomologist Dieter Wittmann in the Venezuelan Amazon, while the paratype was collected by the Brazilian ecologist Elder Ferreira Morato in Reserva Catuaba, Acre State, Brazil. Both specimens are housed at DZUP.

Type data. This species was described based on specimens of both sexes collected in southeastern Brazil. The holotype female and paratypes of both sexes were sent to the MZUSP, but not type specimens are currently housed there. According to the original description, the rest of the paratypes were distributed in DZUP, MNHP, MNRJ, NHMUK, NMNH and OUMNH, however, they were not found in the last five collections.

Philip Timberlake. Philip Hunter Timberlake (1883‒1981) was one of the most prolific American entomologists of the 20th century. He was employed by the United States Department of Agriculture Bureau of Entomology for conducting research in biological control of pest insects (Hurd et al., 1982Hurd, P. D.; Linsley, E. G. & Hall, J. C. 1982. Philip Hunter Timberlake 1883‒1981. Pan-Pacific Entomologist 58:2-18.). Between 1914 and 1924 he was associate entomologist at the Hawaiian Sugar Planters Experiment Station in Honolulu, where his research dealt primarily with biological control using parasites and predators (Hurd et al., 1982). After he leaved Hawaii, he moved to California where he was appointed associate entomologist in the Department of Biological Control at the Citrus Experiment Station of the University of California, Riverside. He stayed there until his retirement in 1950 (Hurd et al., 1982). Timberlake had an extensive knowledge of the taxonomy of parasitic Hymenoptera as well as of native bees. During his stay in Riverside, he made numerous collecting trips especially in southern areas of the state, including the deserts. Encouraged by the renowned naturalist Theodore Dru Alison Cockerell, Timberlake continued his collecting activities and increasing his collection of bees. Cockerell deposited a very sizeable collection of North American bee types in the California Academy of Sciences which were used by Timberlake in his taxonomic studies (Hurd et al., 1982).

During his period of activity, Timberlake described and named about 800 species of bees, including other species in other insect groups. His insect collection contained about 500,000 specimens of which about 150,000 were Hymenoptera (Hurd et al., 1982Hurd, P. D.; Linsley, E. G. & Hall, J. C. 1982. Philip Hunter Timberlake 1883‒1981. Pan-Pacific Entomologist 58:2-18.). His large bee collection served as the foundation for the collection now housed in the University of California’s Entomology Research Museum, containing some 4 million total specimens. Timberlake passed away in Riverside, California, in 1981, aged 97 (Hurd et al., 1982).

Timberlake’s Centris bees. Despite his large knowledge on North American bees, Timberlake published a single paper including species of Centris (Timberlake, 1940). In that article, he cited the species that occur in California, providing some notes on their distribution and floral hosts. In the same article, he described two new species which are currently considered valid. The primary types of both are currently housed at CAS.

Roy Snelling. Roy Robert Snelling (1934‒2008) was an American entomologist who studied ants, wasps and bees. Born of Cherokee Indian heritage in 1934 in Turlock, California, he was basically a self-taught entomologist. Snelling was curator and collections manager in the Los Angeles County Museum of Natural History. In that institution he developed most of his research work, remaining there between 1963 and 1993, when he retired. Snelling was very prolific studying ants and he was much respected among the myrmecological society. He also published articles on wasps and bees, mainly from desert areas of the United States and Mexico (Trager, 2008Trager, J. C. 2008. In memoriam - Roy R. Snelling (30 September 1934 ‒ 21 April 2008). Myrmecological News 11:227-229.). Snelling became interested in insects, mainly on bees and wasps when he was a kid living in the San Joaquin Valley, California. This early interest became his first article on wasps published in 1953, when he was barely out of high school (Trager, 2008Trager, J. C. 2008. In memoriam - Roy R. Snelling (30 September 1934 ‒ 21 April 2008). Myrmecological News 11:227-229.). Although from the beginning he was interested in the nesting biology and other aspects of behavior of aculeate Hymenoptera, his main contributions were on systematics; like most systematists he was an active and enthusiastic collector (Trager, 2008Trager, J. C. 2008. In memoriam - Roy R. Snelling (30 September 1934 ‒ 21 April 2008). Myrmecological News 11:227-229.).

His work on bees, mostly on taxonomy, led to 45 publications that appeared from 1954 to 1997, focused on different taxa. For the genus Hylaeus Fabricius, 1793 (Colletidae), he published numerous papers, with emphasis on the North American and African species. For the genus Centris and its allies, his publications included revisions of North and Central America. He was also interested in the cleptoparasitic subfamily Nomadinae (Apidae) but in this group his contributions were relatively modest (Trager, 2008Trager, J. C. 2008. In memoriam - Roy R. Snelling (30 September 1934 ‒ 21 April 2008). Myrmecological News 11:227-229.). While on an ant expedition in Kenya, Snelling passed away, aged 73.

Snelling’s Centris bees. Among his articles on bees, Snelling published five on Centris species between 1956 and 1988. In those articles he made taxonomic revisions of the species of the genus that occur in North and Central America, describing several new species, proposing new synonymies and citing new distribution records and floral hosts. In that series of publications, Snelling’s knowledge on Centris bees is perceived to be growing, being the article published in 1984 his most extensive and complete. That publication became Snelling’s most famous contribution in the genus, being widely used for the identification of North American species. Despite its relevance, unfortunately that paper contains several errors, mainly related to the fact that Snelling did not study most of the type specimens of the species he cited. This fact led him to identify erroneously some species, as well as proposing new synonymies that are currently considered incorrect.

In total, Snelling described 23 species in Centris, four of them currently synonymized. His last contribution in the genus was the description of C. gavisa Snelling, 1988 from Cerro de La Neblina, southern Venezuela.

Type data. Centris griseola was described based on four females collected by the American botanist, entomologist and pioneer chemist Robert Rickert Dreisbach (1888-1964) in Iguala, Guerrero State, Mexico. In 1907, Dreisbach began his plant collection, but by 1932 his interests had begun to swing to insects, and plant collecting became a secondary but important hobby. Collecting trips took him to many parts of the United States, Mexico, and Central America in search of insects and plant specimens. His insect collection grew to be one of the largest private collections in the nation (Fletcher, 1964Fletcher, F. W. 1964. Robert R. Dreisbach 1888-1964. Journal of Economic Entomology 57(5):796. ).

DISCUSSION

Although at first it may seem irrelevant, the detailed transcription of the labels of the type material is essential to unequivocally recognize the specimen or specimens that were used to describe a certain species.

In many cases, only through this procedure is possible to detect errors or inconsistencies between the information contained in the original descriptions and on the labels of the primary types, allowing in many cases, to confirm or not the identity of a species in particular. This point is especially important in those cases where the species were described based on syntypes, which ended up being distributed in different collections. Probably the best and most emblematic example of this can be observed in the species described by Friese (see Rasmussen & Ascher, 2008Rasmussen, C. & Ascher, J. S. 2008. Heinrich Friese (1860-1948): Names proposed and notes on a pioneer melittologist (Hymenoptera, Anthophila). Zootaxa 1833:1-118.; Rasmussen & Vivallo, 2014Rasmussen, C. & Vivallo, F. 2014. Lectotype designations and new synonymies in the Neotropical bee genus Centris Fabricius, 1804 (Hymenoptera: Apidae). Zootaxa 3856(4):585-594.; Vivallo, 2019cVivallo, F. 2019c. Taxonomic notes, lectotype designations and new synonymies in some species of the bee genus Centris Fabricius, 1804 described by Sándor Mocsáry and Heinrich Friese. Zootaxa 4638(4):534-546. , 2020eVivallo, F. 2020e. Species of the bee genus Centris Fabricius, 1804 described by Heinrich Friese (Hymenoptera: Apidae). Zootaxa 4820(2):231-259. ), whose primary types or type series are found in different museums in Europe and the United States.

It is also interesting to mention that several of the specimens that were used to describe the species studied here were not collected by entomologists specializing in bees, but rather by ecologists, botanists, ornithologists, and zoologists in general. This demonstrates the interactivity that exists between scientists from different areas, which sometimes as a result of their own research, end up providing valuable material for other specialists, in this case, entomologists who had the opportunity to contribute to the knowledge of the biodiversity of bees of the genus Centris.
