Trichocoelina aemula sp. n. Figs 1 B, 3 A, 18 A Material studied . Holotype male . RUSSIA, Krasnodarsk region, Taimyr Nature Reserve, Aru-Mas, 72.50°N, 101.94°E, pan trap, 9–20.VII.2010, A. Barkalov (in ISEA). Paratypes . RUSSIA, same data as holotype, 4 males (in ISEA, MZH, NHMO, SDEI); FINLAND, Li (Lapponia inarensis) (grid 7759292:3539670), sandy river bank, pitfall trap, 13.VI–13.VII.2016, J. Salmela, 3 males (in MZH, PJSR, SDEI). Description . Male. Head . Face and antenna concolorous brown, maxillary palpus pale yellowish. Eye bridge 2–3 facets wide. Face with 13–15 setae. Clypeus with 1–3 setae. Maxillary palpus with 3 segments, 1 st segment as long as or longer than 3 rd segment, 2 nd segment shortest; 1 st segment with 1–2 setae, with dorsal patch of sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 1.7–2.0x as long as wide, the neck shorter than broad, the longest setae shorter than the width of flagellomere. Thorax . Brown, setae pale. Anterior pronotum with 4–6 setae. Proepisternum with 3–10 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 0.6–0.7. stM shorter than fork of M. r-m as long as bM or longer, bM non-setose, r-m with 1–4 setae. Halter yellow. Legs . Yellow, coxal setae pale. Fore tibial organ forming a rather small patch in depression. Fore tibial spur longer than the tibial width. Abdomen . Pale brown, setae pale, short and fine. Hypopygium (Fig. 1 B). Brown, as abdomen. Intergonocoxal area long, with two short, distinctly separate setose lobes (Fig. 18 A). Gonocoxa broad, longer than gonostylus, medial margin basally strongly curved, with sparse and short setosity. Gonostylus (Fig 3 A) broad, laterally roundish, strongly impressed; with short setosity, with a long apical tooth, with 6–7 megasetae in the medial impression, megasetae long and slender, with distinct basal bodies; with 1 well-differentiated whiplash seta on ventromedial margin. Tegmen as long as broad, long and laterally rounded, apically straight, weakly sclerotized, with a dorsal finger-like process, aedeagal teeth not detectable in the specimens studied. Aedeagal apodeme long. BIN . Unknown. Discussion . The basally narrowed gonostylus with a long apical tooth of Trichocoelina aemula sp. n. is almost identical to that of T. biplex sp. n., but differs in having the intergonocoxal lobes of hypopygium much shorter, and the tegmen less strongly narrowed towards apex and without basolateral corners. Because of its rather long gonostylar megasetae, roundish tegmen and short intergonocoxal lobes of hypopygium, T. aemula also resembles T. cochleata (Rübsaamen, 1898) but is distinguished by having the gonostylar apex less strongly curved, paler and with a longer apical tooth of gonostylus, see Fig. 3 A and fig. 377 in Menzel & Mohrig (2000). Etymology . The name is Latin, aemula , comparable, referring to the close resemblance to Trichocoelina biplex sp. n. and T. cochleata. : 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 18, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/4000553 : {"references": ["Rubsaamen, E.
