Summary: | Corynoptera hyperborea sp. n. Fig. 8 A, B Material studied. Holotype male. RUSSIA, Krasnoyarsk region, Taimyr Nature Reserve, Aru-Mas, 72.50°N, 101.94°E, pan trap, 9–20.VII.2010, A. V. Barkalov (in ISEA). Description. Male. Head. Brown, maxillary palpus pale brown, antenna concolorous with face. Eye bridge 2– 3 facets wide. Face with 7 scattered dark and long setae. Clypeus with 1 seta. Maxillary palpus with 3 segments; 1 st segment longer than 2nd segment, 3rd segment shortest; 1 st segment with 1 sharp seta, with a dorsal patch of sensilla. Antennae not visible in the specimen studied. Thorax. Unicolorous brown, setae pale. Anterior pronotum with 3 setae. Proepisternum with 5 setae. Wing. In poor condition in the specimen studied. Length 1.4 mm. Anal lobe small. Veins distinct. R1/R 0.65. c/w 0.65. bM shorter than r-m. bM and r-m non-setose. Halter pale brown, rather long. Legs. Yellowish, setae dark. Fore tibial organ with pale vestiture in small patch. Fore tibial spur longer than the tibial width. Abdomen. Pale brown, paler than thorax, setae dark, rather long and slender. Hypopygium (Fig. 8 A). Pale brown, as abdomen. Gonocoxa strong, longer than gonostylus. The ventral setosity of gonocoxa rather short. Gonocoxae separated. Gonostylus (Fig. 8 B) elongated, medially nearly straight, slightly impressed; with a strong slightly curved apical tooth, with 3–4 subapical megasetae, the megasetae subequal in size, shorter than apical tooth, straight or slightly curved. Tegmen slightly shorter than broad, apically truncate, laterally nearly straight, apically and laterally sclerotized, with small sharp apicolateral lobes, without finger-like process, with small area of aedeagal teeth. Aedeagal apodeme short. Discussion. Corynoptera hyperborea sp. n. resembles Corynoptera perpusilla Winnertz, 1867 but has an apically broader gonostylus, four gonostylar megasetae (not three), and the megasetae are more widely separated from each other and from the apical tooth of the gonostylus. In its tegmen with small sharp ... |
