Trichocoelina tecta sp. n. Figs 15 B, 16 D Material studied . Holotype male . USA, Alaska, 11 mi S Anderson Jct, Rte 3, mi 270, alder-poplar-spruce, Malaise trap, 23.VI–11.VIII.1984, S. & J. Peck (in MZH). Paratypes. USA, same data as holotype, 1 male (MZH); CANADA, Nunavut, Qikitaaluk, Western Bylot Island, 73.157°N, 79.950°W, 12 m, 3.VIII.2007, L. Jolicoeur & L. McKinnon, 1 male (BOLD Sample ID 08WOLVES-01202, in CBG); Yukon, North Fork Crossing, Mi 42 Peel Plt. Road, 3500’, 24.VI.1962, P.J. Skitsko, 1 male (in CNC); RUSSIA, Krasnoyarsk region, Taimyr Peninsula, river Zakharova, Rassokha, 72.70°N, 101.08°E, pan trap, 1–10.VII.2011, A. Barkalov, 1 male (in ISEA); Yamalo-Nenets Autonomous Okrug, near Seyakh, 70.7788°N, 72.0750°E, nival meadow, Malaise trap, 13–29.VII.2014, N. Zubryi, 5 males (1 in MZH, 1 in NHMO, 2 in SDEI, 1 in ZIN). Description . Male. Head . Face and antenna concolorous brown, maxillary palpus pale yellowish. Eye bridge 2–3 facets wide. Face with 13–20 fine setae. Clypeus with 2–5 setae. Maxillary palpus with 3 segments, 1 st segment longer or shorter than 3 rd segment, 2 nd segment shortest; 1 st segment with 1–2 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 1.7–2.25x as long as wide, the neck shorter than broad, the longest setae slightly shorter than the width of flagellomere. Thorax . Brown, setae pale. Anterior pronotum with 2–6 setae. Proepisternum with 3–10 setae. Scutellum with 4 longer and some short and fine setae. Wing . Fumose. Length 1.9–2.1 mm. Width/length 0.40–0.45. Anal lobe weak. Veins distinct. c/w 0.60–0.65. R 1 /R 0.60–0.85. stM and fork of M subequal in length. r-m and bM of variable length, bM non-setose, r-m with 2–4 setae or non-setose. Halter yellow. Legs . Yellow, coxal setae pale. Fore tibial organ forming a small patch of dark strong setae in depression. Fore tibial spur slightly longer than the tibial width. Abdomen . Pale brown, setae pale, moderately long. Hypopygium (Fig. 15 B). Brown, as abdomen. Intergonocoxal area long, basally with strongly sclerotized medial stripe, with large subtriangular lobe with setae at margin. Gonocoxa broad, longer than gonostylus, medial margin basally strongly curved, with long sparse setosity. Gonostylus (Fig. 16 D) long, apically narrowed, strongly impressed; with short setosity, with a long apical tooth, with 6–7 medial megasetae in dorsal and ventral groups, megasetae long and slender, directed slightly differently in both groups; with 1 well-differentiated whiplash seta on ventromedial margin. Tegmen conical, apically and laterally straight or slightly curved, weakly sclerotized, with an indistinct area of minute aedeagal teeth. Aedeagal apodeme long. BIN . BOLD:AAM9263. Discussion . In having a long intergonocoxal lobe of hypopygium and 6–7 medial megasetae on the gonostylus, Trichocoelina tecta sp. n. resembles T. vitticollis (Rübsaamen) but differs in the intergonocoxal lobe being setose only on its margins, not on its ventral side, in its conical tegmen, not apically roundish, and in having the gonostylar megasetae in groups pointed at two directions, not all in a row pointing in one direction. Etymology . The name is Latin, tecta , covered, referring to the ventromedial part of the gonostylus covering almost completely the medial megasetae. : Published as part of Vilkamaa, Pekka & Menzel, Frank, 2019, Re-classification of Lycoriella Frey sensu lato (Diptera, Sciaridae), with description of Trichocoelina gen. n. and twenty new species, pp. 1-67 in Zootaxa 4665 (1) on pages 44-47, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/4000553 |
