Description
Summary:Camptochaeta pertenuis sp. n. Fig. 6 A, B Material studied. Holotype male. RUSSIA, Krasnoyarsk region, Taimyr Peninsula, Taimyr Nat. Res., Aru-Mas, 72.50°N, 101.94°E, pan trap, 9–20.VII.2010, A. V. Barkalov (in ISEA). Description. Male. Head. Face and antenna concolorous brown, maxillary palpus very pale brown. Eye bridge 2–3 facets wide. Face with 12 scattered longer and shorter setae. Clypeus with 1 dark seta. Maxillary palpus with 3 segments; 1 st segment longer than 2nd segment, 3rd segment shortest; 1 st segment with 1 long sharp seta, with a shallow pit of sensilla; body of 4th antennal flagellomere 2.05x as long as wide, surface smooth, neck slightly longer than broad, the longest setae slightly longer than width of flagellomere. Thorax. Brown, setae dark. Anterior pronotum with 7 setae. Proepisternum with 16 setae. Wing. Length 1.8 mm. Width/length 0.45. Anal lobe moderate. R1/R 0.80. c/w 0.65. Veins distinct; stM longer than fork of M, bM longer than r-m, r-m with 2 dorsal setae, bM non-setose. Halter pale brown. Legs. Pale brown. Coxal setae pale. Fore tibial organ with dark vestiture in patch in depression. Fore tibial spur longer than the tibial width. Abdomen. Pale brown, setae dark and rather long and slender. Hypopygium (Fig. 6 A). Brown, concolorous with abdomen. Gonocoxa longer than gonostylus, gonocoxae separated, with rather short medial setosity. Gonostylus (Fig. 6 B) strongly narrowed apically, with the medial side strongly impressed, dorsomedially produced; apicomesially with a few elongated setae; with strong apical tooth, with two megasetae near the apical tooth, one megaseta in subapical position and one megaseta on the dorsomedial margin; megasetae strong and nearly straight, shorter than apical tooth, subapical one with a distinct basal body; with a flagellate seta near the basal-most megaseta. Tegmen broader than long, with large roundish sclerotized basolateral sides, and two apical sclerotized areas, with an area of aedeagal teeth. Aedeagal apodeme short but strong. Discussion. By ...
