| Summary: | Trichocoelina magnifica sp. n. Figs 7 B, 9 C, 17 F Material studied. Holotype male. CANADA, Yukon, North Fork Crossing, Mi 43, Peel Plt. Rd., 3500 ft, 4.VII.1962, R.J. Leech, 1 male (in CNC). Paratypes. CANADA, same data as holotype but 26.VI.1962, 1 male (in MZH); Yukon, Ogilvie Mountains, 7.VII.1962, P.J. Skitsko, 1 male (in MZH). Description. Male. Head. Colours faded in the specimens studied. Eye bridge 2 facets wide. Face with 10–19 fine setae. Clypeus with 2 setae. Maxillary palpus with 3 segments, 1 st segment longer than 3 rd segment, 2 nd segment shortest; 1 st segment with 1–2 setae, with a dorsal patch of sensilla; antennae missing in the specimens studied. Thorax. Colours faded. Anterior pronotum with 6–9 setae. Proepisternum with 13–15 setae. Scutellum with 3 longer and some short and fine setae. Wing. Fumose. Length 2.0– 2.2 mm. Width/length 0.40. Anal lobe weak. Veins distinct. c/w 0.55. R 1 /R 0.60–0.65. stM and fork of M subequal in length. r-m and bm subequal in length. bM non-setose, r-m with 3–4 setae non-setose. Legs. Colours faded. Fore tibial organ forming a small patch of strong setae in depression. Fore tibial spur longer than the tibial width. Abdomen. Colours faded. Hypopygium (Fig. 7 B). Intergonocoxal area long, basally with strongly sclerotized medial stripe, with two distinct setose lobes. Gonocoxa broad, as long as gonostylus, medial margin basally smoothly curved, with normal setosity. Gonostylus (Fig. 9 C) large, laterally roundish, apically slightly narrowed, medially impressed; with short setosity, with a short apical tooth, one megaseta with strong basal body at the apical third and a group of 3 megasetae on common basal body in a more basal position, on the dorsal side of the latter a group of 10–12 megasetae, megasetae rather straight, longer than apical tooth; with a long whiplash seta on ventromedial margin near the basalmost megasetae. Tegmen (Fig. 17 F) longer than broad, apically narrowed, with sharp corners at middle, sclerotized, with large area of small aedeagal ... |
