Coniceromyia camptoneura sp. nov.

( Figs. 2A , 8G , 13G , 18 A–B, 24G)

Diagnosis (male). Anepisternum dorsally setulose, foremetatarsus with one long curved seta at base of excavation and row of three setulae basal to the anteroapical process ( Fig. 8G ).

Material examined. Holotype ♂, USA: Arizona: Cochise Co.: Ramsey Canyon , 31.43°N, 110.31°W, 6– 13.vii.1986, Malaise trap, B. Brown col. [LACM ENT 345889] . Paratypes: 3♂, same as holotype; 1♂, same but 13–24.vii.1986; 1♂, same but 28.vii–2.viii.1986, 1700m; 1♂, same but 8–10.vii.1987, yellow pans, 1950m, B. Brown, T. Spanton col.; 1♂, same but 31.vii.1965, V. Roth col.; 1♂, same but 27.vii.1965.

Description. Male. Body length, 2.2 mm. Head. Frons dark brown, sparsely setulose, with weak median furrow. Flagellomere 1 light brown, conical. Arista apical, 1.5 times flagellomere 1 length. Palpus light brown. Gena with two setae. Thorax. Scutum, scutellum and pleural regions dark brown; anepisternum dorsally setulose. Legs light brown. Forefemur with slightly elongated thin setae in rows along anteroventral and posteroventral margin and ventrally on basal third. Foretibia with two dorsal setae and uneven anterodorsal row of strong setulae. Foremetatarsus with anterior excavation, anteroapical setulose process, one long curved seta at base of excavation, row of three setulae basal to the anteroapical process, and strong curved seta at base of anteroapical process ( Fig. 8G ). Foremetatarsus ratio 0.34. Posterior face of hind femur with basoventral band of tiny blunt setulae, tapering toward ventral margin, dorsal setulae thicker ( Fig. 18 A–B). Hind femur height/length ratio 0.34. Hind tibia with one dorsal seta in basal half. Wing ( Fig. 13G ). Costa swollen, 0.39 of the wing length; R 2 + 3 absent; M 1 mostly straight, curved anteriorly at apex; M 2 sinuous, CuA 1 -M 2 /M 2 -M 1 ratio 1.21; CuA 1 slightly sinuous. Halter whitish to light brown.

Abdomen. Tergites brown to dark brown, with shining pubescence. Hypopygium light brown ( Figs. 24G ). Left epandrial process dorsally and apically setose, without conspicuous processes except a subepandrial setose elevation near hypoproct. Margin of right lobe of hypandrium without projections. Hypoproct with eight setae.

Distribution. Known from a single site in Southern USA.

Etymology. Name derived from the Greek roots kamptos (bent, curved) and neuron (nerve, tendon), referring to the convexity in the apical third of the wing vein M 2.

Variations. Specimens with longer foremetatarsus; wing vein M 2 with a slight convexity; hypopygium with a lobe near base of left epandrial process.
