Comyops nigripennis Wulp 1891: 262 View in CoL . References. Brauer & Bergenstamm (1893: 183, designation of C. nigripennis as type species of Comyops ); Thompson (1963: 472, redescription of male; 474, description of first instar larva); Guimarães 1971: 109, catalogue); O’Hara et al.

Remark. At the NHMUK collection the two male syntypes from the original description of Wulp were examined by D.M. Wood. One male presents a lectotype label and the other male a paralectotype label attached by Wood in 1989. However, the lectotype designation was not published. In the interests of nomenclatural stability and to restrict the name to a single specimen, the male syntype bearing Wood’s lectotype label and the additional label “NHMUK 013933635” is hereby designated as lectotype of Comyops nigripennis Wulp 1891 .

The current combination for this species is Ebenia nigripennis ( Wulp, 1891) comb. nov.

Diagnosis. Eyes with conspicuous setulae. Fronto-orbital plate dark silver pruinose. Postpedicel entirely dark brown. Facial ridge with setulae present almost at the antennal insertion. Prosternum setulose. Thorax without silver pruinosity. Legs brownish black. Wing smoky, mainly on apical portion; veinR 4+5 with setulae dorsally hallway to r-m. Costal spine poorly developed. Abdomen with silvery pruinosity on each tergite, occupying just anterior margin, about 1/5 of each segment. Male terminalia with surstylus presenting long setulae laterally on frontal view.

Redescription of lectotype male.

Coloration ( Fig. 6a–c View Fig ): Occiput with silver pruinosity. Head with dark silver pruinosity. Antenna dark brown. Arista dark brown, but proximal 1/5 light brown. Palpus brownish. Labellum light brown, prementum shiny black. Scutum brownish, but posterior part of the postpronotal lobe silvery pruinose. Wing smoky on apical region. Tegula and basicosta dark brown. Halter yellowish. Posterior spiracle light-brown. Legs brownish. Upper and lower calypters hyaline. Abdomen brownish, with brownish pruinosity only visible on posterior view, occupying about the entire surface of tergite 3 and 4.

Head ( Fig. 6a–c View Fig ): Vertex about 0.1 × head width in dorsal view. Width of parafacial, measured at distance between inner margin of eye and antennal insertion, 2× height of gena. Fronto-orbital plate with setulae throughout its length. Frontal vitta narrowed dorsally. Eye about 0.9× the head height. Gena about 0.1 ×eye height. Labellum developed, about 0.1x as long as prementum.

Thorax ( Fig. 6a, c View Fig ): Acrostichal setae 2 + 1. Dorsocentral setae 2 + 3. Prosternum setulose. Anepisternum with one seat on anterior upward region. setulose. Wing. Costal spine poorly developed. Vein R 4+5 with setulae dorsally hallway to vein r-m and ventrally just at base. Legs. Fore femur with posterodorsal and posteroventral rows of setae; fore tibia with 1 posteroventral on distal third, 2 preapical, 1 anterodorsal and 1 posteroventral setae. Mid tibia with 3 anteroventral, 3 posteroventral setae on apical third; mid femur with anterodorsal setae on apical third, 2 preapical, and 2 posteroventral setae. Hind femur with posterodorsal and posteroventral rows of setae. hind tibia with 5 anterodorsal setae, and 1 postodorsal setae on distal third, 2 preapicals, 2 anterodorsal setae.

Abdomen ( Fig. 6a, c View Fig ): Syntergite 1 + 2 with mid-dorsal longitudinal depression extending until ½ to posterior margin. Syntergite 1 + 2 with at least 4 pairs of lateral marginal setae; tergite 3 with at least 4 pairs of lateral marginal setae and a pair of median marginal seta.

Terminalia ( Fig. 7 View Fig ): Sternite 5 with slightly developed lobules, setulose, with basal plate long and slightly curved; sensilla “ trichodea ” present on distal portion. Epandrium broad in posterior view, setulose, and closed dorsally. Surstylus somewhat narrow, not fused with epandrium, convex, setulose in posterior view and with about 10 long setulae laterally on posterior view; distally tapered in lateral view ( Fig. 7A, C View Fig ). Extension of dorsal sclerite of distiphallus ending in a confluent region.

Female. Following the description of Thompson (1963: 472), it differs from male by the following: head with vertex about 4x width of front. Ocellar setae weak, proclinate-divergent. A pair of strong proclinate orbitals and between these but near the anterior

orbital, a strong reclinate frontal seta. Abdominal tergite 1+ 2 with no marginal or discal setae, but a pair of strong lateral setae.

First instar larvae. A complete description was given by Thompson (1963: 474), and the reader is referred to that work.

Biology. Unknown.

Distribution. Mexico, Trinidad & Tobago and Brazil (Rio de Janeiro, new record).
