The biological collections of the Instituto Nacional de Pesquisas da Amazônia (INPA) are a significant resource of information about Amazonian biodiversity. The strengths of the collections lie in the fauna and flora of the western Brazilian Amazon, but many groups are representated from all over the Amazon region. In 1994, an institutional program was created to improve curatorial procedures, to establish and unify curatorial policies, and to integrate activities of the various botanical, microbiological and zoological collections of the Institute. The Collection of Invertebrates assembles the holdings of 14 invertebrate groups: Acanthocephala, Annelida, Arachnida, Chilopoda, Crustacea, Diplopoda, Insecta, Mollusca, Nematoda, Plathyhelminthes, Pauropoda, Porifera, Rotifera, and Symphyla, each one organized independently. Except for Insecta, all others are organized according to lots.

The Collection of Invertebrates was formally established in October, 1976 (RATCLIFFE 1978, RATCLIFFE & PENNY 1978a). Its first catalogue of type specimens appeared soon afterwards (RATCLIFFE & PENNY 1978b) and included primary and secondary types of 139 species, 33 (23.7%) of which pertaining to four non-insect groups. Five years later, the catalogue published by RAFAEL et al. (1983) listed type specimens for 334 species, with 81 pertaining to six non-insect taxa. Updates of this catalogue were restricted to the types of the Crustacea collection (MAGALHÃES et al. 1988), and to the types of the Tabanidae (Diptera) collection (HENRIQUES 1995). During the last two decades the collection has grown quickly and the number of type specimens increased substantially since the publication of the last catalogue. The large number of types currently deposited in the collection would make it impractical to prepare a comprehensive listing of all type specimens of invertebrates in a single volume. Therefore, it was decided that listings for each group should appear separately in a sequentially numbered series of catalogues in the order that each subcollection is reorganized. These listings were prepared both to cope with the Recommendation 72F.4 of the International Code of Zoological Nomenclature (ICZN 1999) and as a preparation for databasing the collections.

In this report, the first of a series, the putative type specimens included in the phyla Acanthocephala, Nematoda and Rotifera, deposited in the Collection of Invertebrates at INPA, and whose descriptions were published up to 31 July 2005 are covered.

 

MATERIAL AND METHODS

The holdings of Acanthocephala, Nematoda and Rotifera in the Invertebrate Collection resulted from the systematic and faunistic studies of INPA's researchers and collaborators. The material came primarily from field work of the scientific staff of INPA and of foreign institutions working in collaboration with INPA, particularly the " Max-Planck-Institut für Limnologie, Arbeitsgruppe Tropenökologie" (Plön, Germany) (ADIS et al. 1985). All specimens are preserved as microscope slide preparations, except for some Nematoda specimens stored in glass vials and preserved in 70% ethanol. All material is available for consultation, except when otherwise noted.

Each collection has its own numbering system encompassing both type and non-type specimens. The registration number is prefaced by the acronym " INPA" . Specimens from the same lot (i.e., coming from the same collecting event) preserved on separated microscope slides are differentiated by lower case letters (e.g., INPA 002a-b). Because the registration system was established together with the present reorganization of these collections, the numbers that appeared in the descriptions of some species actually correspond to other numbering systems (collector's field number or author's personal control number, for instance).

The catalogue is arranged alphabetically from high to low taxonomic rank. Original spelling and combinations were preserved and no attempt was made to update eventual changes in synonymies or new generic combinations. Information for each entry is presented in the following format: species and subspecies (where noted), author(s), year of publication, followed by page number in which the species description first appeared, figure(s), and the genus (subgenus). Primary type status: sex, INPA and respective collection number of the specimen, mode of preparartion (in case of being in vials), locality (country, state/department/province, specific locality). In the case of parasitic species, the name and authority of the host fish species and site of infection, when available, is provided between brackets. For secondary types, only the number and sex of specimens, and INPA collection number(s) are usually provided. The categories for primary and secondary types used follows the definitions of Articles 73-75 of the ICZN (1999). Remarks sections are inserted where necessary and include additional discussion such as nomenclatural questions, indication of missing and exchanged types, and discrepancies between information in the original publication and those found when the lots were inventoried, particularly those concerning the number of specimens and their collection numbers.

Bibliographic information includes publications in which the species was described and those that mention deposition of the type(s) in INPA's Invertebrate Collection. The following abbreviations were used: (CHIOC) Coleção Helmintológica do Instituto Oswaldo Cruz, Rio de Janeiro, Brazil; (HWML) University of Nebraska State Museum, The Harold W. Manter Laboratory of Parasitology, Lincoln, USA; (INPA) Instituto Nacional de Pesquisas da Amazônia, Manaus, Brazil; (IPASCR) Institute of Parasitology, Academy of Sciences of the Czech Republic, Helminthological Collection, Ceské Budejovice, Czech Republic; (KBIN) Royal Belgian Institute for Natural Sciences, Brussels, Belgium; (MZUSP) Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil; (NHML) The Natural History Museum, London, England; (RUCA) Department of Biology, (FEP) University of Antwerp, Belgium (collection W.H. De Smet); (RUG) University of Gent, Belgium; (SMF) Forschungsinstitut und Naturmuseum Senckenberg, Frankfurt/Main, Germany.

 

RESULTS

As of July 2005, the Acanthocephala collection was composed of five nominal fish parasite species and included 10 lots (3 of holotypes; 6 of paratypes) with 36 specimens; the Nematoda collection had 11 nominal fish parasite species and included 33 lots (9 of holotypes; 16 of paratypes), with 134 specimens; the Rotifera collection had 73 free-living nominal species and subspecies and included 95 lots (12 of holotypes; 6 of lectotypes; 9 of paratypes; 5 of paralectotypes), with 96 specimens and one trophi preparation. Material of 42 out of the 95 species of Rotifera listed by ADIS et al. (1985) as having been deposited by the scientific staff and associates of the Max-Planck Institut for Limnology (Plön, Germany) between 1940 and 1982 in INPA's collection was not found. This material may have either been misplaced in the Collection or perhaps it is still being kept by specialists.

Specimens of two Rotifera species were listed in former catalogues (RATCLIFFE & PENNY 1978b, RAFAEL et al. 1983) as being holotypes. A closer examination of the data associated to these material revealed that they cannot be considered as such. The material is the following:

Lepadella benjamini brasiliensis Koste, 1972. The slide INPA 009 has a left label with the identification and a handwritten number " 12" , and a right label with the data " Fundort: Santarem Amazonas, Dat.: 1.VII.46, leg. H. Sioli, Glyz. Gel." . ADIS et al. (1985) mentioned that the specimen in this slide is the holotype. However, KOSTE (1972: 401) did not designate a holotype, and the material he examined came from different localities: " Rio Branco vor Boa Vista, 17.IX.1941" (locality # 46) and " Wasser des Rio Curuá, bei Alenquer, 15.VII.1946" (locality # 66). It seems that the specimen in slide INPA 009 was not originally included in the type material and, therefore, should not be the holotype. The syntypes were not located.

Lepadella monodactyla caudata Koste, 1972. The slide INPA 011 has a left label with the identification and a handwritten number " 15" , and a right label with the data " Fundort: Igarapé Curui, Dat.: 17.X.59, leg. H. Sioli, Glyz. Gel., II/71" (Igarapé Curui is a southern tributary of the Amazon river between Santo Antônio do Içá and São Paulo da Olivença, state of Amazonas, Brazil). ADIS et al. (1985) mentioned that the specimen in this slide is the holotype. However, KOSTE (1972: 405) did not designate a holotype and he did not include this locality among the occurrences of the material mentioned by him in the original description of this subspecies, which were " Poço II bei Maués, 26.i.1941" (locality # 25), " Rio Cupari, lower Rio Tapajós, 29.vii.1946" (locality # 70), and " Rio Maués-açú, 15.xi.1959" (locality # 156). It seems that the specimen in slide INPA 011 was not originally included in the type material and, therefore, should not be the holotype. Once again, the destination of the syntypes is unknown.

ALTHERR (1972, 1977) described several new species of Nematoda from a collection made by W. Sattler in 1961 in interstitial waters near Benfica (01º18'S, 48º18'W) in the vicinity of Belém, state of Pará, Brazil, and stated that the types were deposited at INPA. However, these types have never been found in the Collection of Invertebrates at INPA and they were not listed in its two former catalogues of type specimens (RATCLIFFE & PENNY 1978b, RAFAEL et al. 1983). Edmond Altherr died in November of 1976, and he probably did not have the opportunity to send these types back to INPA. The specimens should still be deposited in the " Service de Nématologie" of the " Station Fédérale de Recherches Agronomiques de Changins" , in Nyon, Switzerland, as VALLOTTON (1979) mentioned that Altherr bequeathed his type collection to that institution. The types stated by ALTHERR (1972, 1977) as being deposited at INPA are the following:

(1985), indicated which slide should be the holotype. As the author did not designate the type material in the original publication (KOSTE 1972), such indication should be considered lecto- and paralectotype designations according to the Article 74.5 of the ICZN (1999). INPA has other slides from the same collecting event in the Rotifera collection (INPA 028a-e).

Remarks: These specimens were listed as syntypes in former catalogues (RATCLIFFE & PENNY 1978b, RAFAEL et al. 1983). However, Koste in a personal communication to ADIS et al. (1985) indicated which slide should be the holotype. As the author did not designate the holotype in the original publication (KOSTE 1972), such indications should be considered a lectotype designation according to the Article 74.5 of the ICZN (1999).

(1985) indicated that the slide marked with the number " 20" (handwritten) should be the holotype. However, as the author did not designate the holotype in the original publication (KOSTE 1972), such indication should be considered a lectotype designation according to the Article 74.5 of the ICZN (1999).

Remarks: Paratypes are also deposited in the collections of the KBIN and RUG.

Trichotriidae

altamirai braziliensis Koste, 1972: 407, pl. 38. Macrochaetus

Lectotype: INPA 013; Brazil, Pará, Rio Curuçambá, ca. 10 km eastern from Óbidos [lectotype designated by Koste in ADIS et al. (1985)].

Remarks: This specimen was listed as the holotype in former catalogues (RATCLIFFE & PENNY 1978b, RAFAEL et al. 1983). ADIS et al. (1985) indicated that the slide marked with the number " 18" (handwritten) should be the holotype. However, as the author did not designate the holotype in the original publication (KOSTE 1972), such indication should be considered a lectotype designation according to the Article 74.5 of the ICZN (1999).

americanus Segers & Sarma, 1993: 178, fig. 1a-b. Macrochaetus

Holotype: female, INPA 048; Brazil, Roraima, about 7 Km S. of Boa Vista, permanent lagoon of Rio Branco.

Remarks: Paratypes are also deposited in the collections of the KBIN and RUG.

aspinus Segers & Sarma, 1993: 178, fig. 2a-b. Macrochaetus

Holotype: female, INPA 049; Brazil, Roraima, about 7 Km S. of Boa Vista, permanent lagoon of Rio Branco.

Remarks: Paratypes are also deposited in the collections of the KBIN and RUG.
