Coniceromyia cristifemur Borgmeier

( Figs. 67–70, 159, 211, 273)

Coniceromyia cristifemur Borgmeier, 1969 b: 59 , figs. 25–27.

Diagnosis (male). Hypopygium left epandrial process without conspicuous external projections except subepandrial elevation bearing three pointed projections. These characteristics are present also in C. costaricana , from which C. cristifemur can be differentiated by its anepisternum setulose and foremetatarsus not expanded anteriorly.

Material examined. Holotype, ♂, COSTA RICA, La Suiza, vii. 1926 Pablo Schild col. (MZSP); 2 ♂ paratypes, same data as holotype.

Redescription. Male. Body length, 1.8 –2.0 mm. Head. Frons dark brown, sparsely setulose, with welldefined median furrow. Flagellomere 1 brown, pubescent, elongate-conical. Arista apical, pubescent, about the same length of flagellomere 1. Palpus yellowish-brown; two genal setae. Thorax. Scutum, scutellum and pleural regions dark brown, anepisternum setulose dorsally. Legs yellowish-brown. Foretibia with two dorsal setae and anterodorsal row of strong setulae ( Fig. 159). Foremetatarsus with anteroapical setulose process, anterior excavation, long seta on excavation base and seta on the base of the anteroapical process. Hind femur swollen (height/length ratio, 0.4), with posteroventral group of tiny blunt setulae with semicircular distribution, tapering toward ventral margin—dorsal setulae thicker ( Fig. 273). Hind tibia with one dorsal seta. Wing ( Fig. 211). Costa not swollen, 0.36 of the wing length; M 1 slightly concave, curved posteriorly at apex; M 2 slightly sinuous; anteroposterior distance between M 2 and CuA 1 at CuA 1 apex about 1.3 times the distance between M 1 and M 2 at the same level; CuA 1 slighlty sinuous. Halter yellow. Abdomen. Tergites dark brown, with lighter posterior band. Hypopygium light brown ( Figs. 67–70). Epandrium covered with microtrichia mostly dorsally, proximal lateral areas bare; epandrium dorsal suture absent; left suture present. Left epandrial process dorsally setose, with subepandrial elevation bearing three pointed projections ( Figs. 68 and 70, black arrow). Right epandrial projection with subepandrial group of setulae. Hypoproct with two setae. Hypandrium without lateral projections.

Geographical distribution. Costa Rica.

Comments. Besides the hypopygium description, the main complements to the original description of Coniceromyia cristifemur (Borgmeier, 1969 b) are the recognition for this species of the foretibia anterodorsal row of strong setulae, the foremetatarsus long seta at the base of the excavation, and the seta at the base of the anteroapical process.
