ABSTRACT

Laelius Ashmead includes 54 known nominal species worldwide. We present a revision of the Neotropical species of Laelius and provide keys for the identification of males and females of these species. We propose fourteen nomenclatural changes and additions. For the Neotropics, seven new species from Brazil are described and illustrated: Laelius arryni sp. nov. which has clypeus bearing median lobe with apical margin straight; propodeal disc with inner discal carina complete; aedeagus with apical lobes touching each other and inner margin with hook-shaped process, L. baratheoni sp. nov. which has propodeal disc with second pair of discal carinae incomplete; genitalia with paramere wing-shaped; with long setae around the margin and cuspis wide, L. lannisteri sp. nov. which has median lobe of clypeus with apical margin straight; mesopleuron with mesopleural suture distinct; genitalia with paramere slender and angled, cuspis wide, L. martelli sp. nov. which has pronotum with series of foveae posteriorly; genitalia with paramere slender and placed dorsally, aedeagus not reaching apex of paramere, L. targaryeni sp. nov. which has head with clypeus wide and with apical margin rounded; propodeal disc without longitudinal ridge between median and inner discal carinae; forewing with r-rs & Rs longer than Rs+M, L. tullyi sp. nov. which has head densely punctate; pronotal disc, mesoscutum and mesoscutellum rugulose; mesopleuron with mesopleural suture not fused with posterior fovea, L. starki sp. nov. which has mesoscutellar sulcus straight; mesopleuron with all foveae closed; genitalia with paramere club-shaped and with aedeagus wide. For the Nearctic region, Laelius areolatus (Rosmann & Azevedo, 2005) is a new junior synonym of Laelius pedatus (Say, 1836) and lectotypes for L. rufipes Ashmead, 1893, L. nigripilosus Ashmead, 1893, L. tricarinatus Ashmead, 1893, L. trogodermatis Ashmaed, 1893, and Mesitius nigripilosus Ashmead, 1895 are designated. We also propose the name Laelius billi Barbosa & Azevedo nom. nov. for Mesitius nigripilosus Ashmead, 1895 and re-erect Laelius huachucae (Evans, 1965) from L. nigripilosus (Ashmead, 1895). As result, Laelius now includes 61 species, 15 of which are from the Neotropical region.

Key words: Epyrinae; key; Neotropical region; new species; type revision


 

 

The cosmopolitan Laelius Ashmead, 1893 comprises 54 nominal species: 21 from the Palaearctic, nine from the Nearctic, nine from the Neotropical, three from the Afrotropical, four from the Oriental, and two from the Australian region. There are also four fossil species (BARBOSA et al. 2013). ASHMEAD (1893) first described Laelius to include four Nearctic species that had the forewing with two basal closed cells and short but distinct r-rs and Rs. The genus is classified in Epyrini due to the presence of a projected clypeal median lobe and antennae with 13 segments (EVANS 1964).

Most keys to the genera of Epyrini (see EVANS 1964, TERAYAMA 2003, AZEVEDO 2006) consider the presence of a short r-rs & Rs in the forewing as the main character defining Laelius. However, only the key provided by EVANS (1964) separates Laelius from the other genera, based on the presence of black setae on the body surface and on the main wing veins. WAICHERT & AZEVEDO (2009) and BARBOSA & AZEVEDO (2011) retrieved this characteristic as the main synapomorphy of the genus. We adopt this classification and treat Laelius in the Epyrinae.

The main goal of the present paper is to describe seven new species of Laelius, revise the type species of the genus recorded from the Neotropical region, and provide information on some Nearctic species.

 

MATERIAL AND METHODS

The material examined belongs to the following collections: CASC – California Academy of Sciences, San Francisco (Robert Zuparko); CNCI – Canadian National Collection of Insects, Ottawa (John Huber); CEPLAC – Comissão Executiva do Plano da Lavoura Cacaueira, Ilhéus (Jean Jacques Delabie); DZUP – Universidade Federal do Paraná, Curitiba (Gabriel Melo); IBGE – Instituto Brasileiro de Geografia e Estatística, Brasília (Mauro César); INPA – Instituto Nacional de Pesquisas da Amazônia, Manaus (Augusto Henriques); LACM – Los Angeles County Museum, Los Angeles (Brian Brown); MPEG – Museu Paraense Emílio Goeldi, Belém (Orlando Tobias); MZSP – Museu de Zoologia da Universidade de São Paulo, São Paulo (Carlos R. F. Brandão); SEAN – Museo Entomológico de Léon, Léon (Jean-Michel Maes); UFES – Universidade Federal do Espírito Santo, Vitória (Marcelo Tavares).

Measurements and indices used in this study are as follows: body length, measured from apex of clypeus to posterior margin of last metasomal segment, excluding male genitalia or female sting; (LH) length of head, measured in frontal view from vertex crest to median apical margin of clypeus; (WH) maximum width of head, measured in frontal view, including eyes; (WF) minimum width of frons, measured in frontal view, usually at the level of the base of eye bases; (HE) maximum height (length) of eye, measured in lateral view; (OOL) ocelloocular line, measured in laterodorsal view, the shortest distance from eye top to posterior ocellus; (WOT) width of ocellar triangle, measured in frontal view, maximum width, including ocelli; (DAO) diameter of anterior ocellus, measured in frontal view; distance of ocellar triangle to vertex, measured in dorsoposterior view; distance from posterior ocellus to vertex crest; (VOL) vertex-ocular line, measured in dorsal view, distance from eye top to vertex crest.

Terms used to describe body structures generally follow BARBOSA & AZEVEDO (2009), DUPORTE (1965), EVANS (1964), GIBSON (1986), GOULET & HUBER (1993), MIKÓ et al. (2007), RICHARDS (1977), RONQUIST & NORDLANDER (1989), but those related to the integument follow HARRIS (1979).

The descriptions were elaborated with DELTA (Descriptive Language for Taxonomy) as proposed by DALLWITZ et al. (1993). All species were described based on the holotype, and the characteristics that are not present in the holotype are mentioned in the topic "Variations" of the species' description.

In the material examined section, additional information is in brackets. Label information is reproduced in the original language, except for the country.

The male genitalia of L. gracilis, L. multilineatus, and L. muesebecki are described and illustrated for the first time. As we had the opportunity to study types of several New World species, we also present comments on some Nearctic species.

The specific epithets of all new species are derived from some families of the book "A Song of Ice and Fire, Game of Thrones" (MARTIN 1996), and the new name of L. nigripilosus is given after the original author of the species.

Remarks. This species was known from the U.S.A. (Arizona and California) and Mexico (Durango) and is now recorded for the first time from the Dominican Republic (San Cristóbal), Nicaragua (Granada and San Juan del Sur), Trinidad and Tobago (Arima), and Brazil (Amazonas, Bahia, Distrito Federal, Espírito Santo, Minas Gerais, Pará, Rio Grande do Norte and São Paulo).

Although the list of studied material is fairly large, we did not observe significant intraspecific variation. Only the proportion between LH x WH varies among the specimens analyzed. This species is promptly recognized by having the head remarkably longer than wide, LH is usually at least 1.2 x WH, whereas in other species it is 1.0 x WH or less.

Remarks. This species was known from Panama (Barro Colorado Island) and Brazil (Santa Catarina), and it is now recorded for the first time from Amazonas, Pará, Maranhão, Bahia, Distrito Federal, Minas Gerais, Espírito Santo, São Paulo, Paraná, and Rio Grande do Sul.

The specimens of the type series of L. hirticulus have no longitudinal ridge between the median and inner discal carinae. In the material analized by us, however, some specimens have a longitudinal ridge. The presence or absence of this sculpture was considered as intraspecific variation by BARBOSA & AZEVEDO (2009, 2011).

Remarks. The original description was based on a couple. The male is presently designated as the lectotype and the female as the paralectotype.

The characters of L. areolatus agree with those of L. pedatus, including the short length of 2R1 of forewing. Therefore, we synonymize the former under the latter.

Notes on Nearctic species of Laelius Laelius centratus (Say, 1836)

Bethylus centratus Say, 1836: 281.

Paralaelius centratus (Say, 1836): combined by Kieffer, 1908: 39.

Laelius centratus (Say, 1836): combined by Muesebeck & Walkley, 1951: 728.

Laelius trogodermatis Ashmead, 1893: 50, 51.

Laelius occidentalis Whittaker, 1929 [1928]: 387-388.

Diagnosis. Female. Body 3.6 mm. Dark castaneous, forewing hyaline. Mandible with five sharpened apical teeth. Clypeus with median lobe trapezoidal with apical margin straight. Frons coriaceous, punctures inconspicuous. WH 1.07 x LH, WF 0.56 x WH, WF 1.2 x HE, VOL 0.53 x HE; OOL 0.67 x WOT. Frontal angle of ocellar triangle almost right, posterior ocellus touching vertex crest. Vertex slightly convex. Mesoscutum with notaulus and parapsidal signum conspicuous and incomplete anteriorly. Propodeal disc 0.96 x as long as wide; with five discal carinae, median carina complete; with longitudinal ridge between median and inner discal carinae; inner discal carina incomplete; with longitudinal ridge between inner and second pair of discal carinae; second pair of discal carinae incomplete. Declivity of propodeum with median carina weak. R-rs & Rs 0.7 x as long as Rs+M, straight. Metasoma missing.

Material examined. Syntype female of Laelius trogodermatis Ashmead, 1893; here designated as lectotype: [U.S.A.], D[istrict of] C[olumbia], 3575, par[as]i[ting] on Trogoderma tarsele found in Belfrage Coll[ection], 1.xi.[18]84 (USNM #2187); holotype of Laellius occidentalis Whittaker, 1929 [1928]: CANADA, B[ritish] C[olumbia], Chilliwack, 24.vi.1926, O. Whittaker Coll[ector] per W.H. Storey, B.M. 1947-212 (BMNH). Voucher: MEXICO, 1 female, Baja Cal[ifornia] N[orte], Bahia de Los Angeles, vi.1996, ~1m in land, T. Jackson (CNCI).

Remarks. This species was known from Canada, U.S.A., and Mexico. The known distribution indicates that L. centratus probably is restricted to the Nearctic region. It is promptly recognized by its broad ocellar triangle.

The type of this species, which is supposed to be at USNM, has apparently been lost. Laelius trogodermatis was described based on a couple, but both syntypes deposited at USNM are females. Here we considered the specimen with code USNM #2187, deposited at the primary type collection, as the lectotype.

Laelius huachucae (Evans, 1965) stat. rev.

Rhabdepyris (Rhabdepyris) huachucae Evans, 1965: 71, 73-74, 80, 84-85.

Mesitius nigripilosus Ashmead, 1895: 539 nec Laelius nigripilosus Ashmeand, 1893 et nec Rhabdepyris nigropilosus Evans, 1966 [1965]. Synonym by Evans (1966 [1965]): 268.

Laelius huachucae (Evans, 1965): combined by Waichert & Azevedo, 2009: 23.

Diagnosis. Female. Body 4.65 mm. Dark castaneous to nearly black, forewing hyaline. Mandible with five apical sharpened teeth, two lowermost teeth wider than others. Clypeus with median lobe trapezoidal with apical margin angulate. Frons strongly coriaceous. WH 0.92 x LH; WF 0.59 x WH; WF 1.57 x HE; VOL 0.7 x HE; OOL 1.1 x WOT, frontal angle of ocellar triangle right, posterior ocellus distant from vertex crest 0.5 x DAO. Vertex slightly convex. Pronotal disc without series of foveae posteriorly. Mesocutum with notaulus complete, wide, and converging posteriorly; parapsidal signum incomplete. Propodeal disc 1.38 x as long as wide; with five discal carinae, median discal carina complete; with longitudinal ridge between median and inner discal carina; inner discal carina complete; with longitudinal ridge between inner and second pair of discal carinae; second discal carina incomplete; sublateral and lateral carinae conspicuous. Declivity areolate with median carina. Mesopleuron lower and posterior fovea fused; posterior fovea not fused with mesopleural suture.

Material examined. Holotype female: [U.S.A.], Ariz[ona], Huachucal Mts., Ramsey C[anyo]n, F.G. Werner & G.D. Butler col[lector] (MCZH #30936).

Remarks. This species cannot be treated as a junior synonym of L. billi nom. nov. as established by Evans (1966) because the former has the head with eye large and ocelli small, the mesopleuron with lower and posterior foveae fused, the propodeal disc with inner discal carina complete, whereas the latter has the head with eye small and ocelli large, the mesopleuron with lower and posterior foveae not fused, the propodeal disc with inner discal carina incomplete.
