Trichocoelina semisphaera sp. n. Figs 14 B, 16 B Material studied . Holotype male. FINLAND, Lkor (Lapponia kemensis orientalis), Salla, Värriö, Kuntasjoki (grid 7520406:3610772), over a brook, Malaise trap, 29.VII–19.IX.2013, J. Salmela (in MZH). Paratypes. FINLAND, Ks (Regio kuusamoensis), Taivalkoski, Kylmäoja (grid 7275293:3554865), by a brook, Malaise trap, 3.VII– 1.VIII.2006, J. Salmela, 1 male (in PJSR); NORWAY, ‘ Svalbard, Lakselva’ [= Svalbard, Bjørnøya, river Lakselva], 74.4994°N, 18.9776°E, 15 m, 28.VII.2009, T. Ekrem, 1 male (NTNU-VM 50613 and BOLD Sample ID BJ263, in NTNU-VM). Description . Male. Head . Face brown, antenna darker brown, maxillary palpus pale yellowish. Eye bridge 2–3 facets wide. Face with 24–26 fine setae. Clypeus with 2–3 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; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 1.95–2.0x as long as wide, the neck shorter than broad, the longest setae slightly shorter than the width of flagellomere. Thorax . Brown, setae dark. Anterior pronotum with 4–7 setae. Proepisternum with 6–8 setae. Scutellum with 4 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 0.65–0.75. R 1 /R 0.50–0.60. stM slightly shorter than fork of M. r-m longer than bM, bM non-setose, r-m with 3–4 setae. Halter yellow. Legs . Yellow, coxal setae pale. Fore tibial organ forming a large indistinct patch of fine setae in depression. Fore tibial spur longer than the tibial width. Abdomen . Pale brown, setae dark, moderately long. Hypopygium (Fig. 14 B). Brown, as abdomen. Intergonocoxal area long, with large conical setose lobe. Gonocoxa broad, as long as gonostylus, medial margin basally strongly curved, with short sparse setosity. Gonostylus (Fig. 16 B) broad, laterally roundish, apically narrowed, strongly impressed; with short setosity, a short curved apical tooth, and a dorsal and a ventral group of 6–7 megasetae medially; megasetae long and slender, directed slightly differently in both groups; with 1–2 weakly differentiated whiplash setae on ventromedial margin. Tegmen subconical and sclerotized, with area of minute aedeagal teeth. Aedeagal apodeme narrow and rather short. BIN . BOLD:ABA5290. Discussion . By the subtriangular form of its gonostylus, Trichocoelina semisphaera sp. n. resembles T. hiemalis (Mohrig & Mamaev) but differs in having two groups of gonostylar megasetae, pointing in slightly different directions (all similarly directed in T. hiemalis ), and one long intergonocoxal lobe of hypogium (two small ones in T. hiemalis ) and in having the tegmen subconical (roundish in T. hiemalis ). Etymology . The name is derived from the Latin words semi -, half, and sphaera , ball, referring to the roundish lateral margin of the gonostylus. : 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 page 43, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/4000553 |
