Large, anal lobe strong, hind veins distinct, stCuA short, 1/3 of bM; bM = r-m, bM non-setose, r-m with 4–5 setae distally, c/w 0.50. Body length 2,7 mm, wing length 2,5 mm. BIN. Unknown. Discussion. The species was described from females from Northern Norway by Lengersdorf (1926): for the lectotype designation and literature, see Menzel & Mohrig (2000). After a study of the lectotype, which so far is the only specimen of the species (in ZFMK) available for study, Menzel & Mohrig (2000) stated that the scutellum has many long and strong setae, the 1 st palpal segment has a unbordered patch of sensilla, the fore tibia has spine-like setae, and that R 1 /R complex is long (R 1 ends near the level of the base of the M-fork). We have studied the lectotype again and have found characters that might be helpful in identification of the male of this species and for supporting its placement in the genus Trichocoelina. Of the characters given above, only the somewhat unequally long spurs of the mid and hind tibiae as well as the high number of long scutellars are unusual for Trichocoelina.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 19, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/400055

The species was described from Greenland (Rübsaamen, 1898), and redescribed and illustrated by Menzel & Mohrig (2000), with the discussion of the type material. Trichocoelina cochleata is characterized by having a medially impressed gonostylus, with a strongly curved apical part. The antennal scapus and pedicellus as well as the hypopygium and legs are yellow, but the apex of gonostylus has strikingly dark setosity. The gonostylus bears 6–7 rather long and slender gonostylar megasetae, the tegmen is broadly subconical with a sclerotized dorsoapical process. The intergonocoxal lobes of the hypopygium are short.

Face and antenna concolorous brown, maxillary palpus pale brown. Eye bridge 3 facets wide. Face with 14 setae. Clypeus with 4 setae. Maxillary palpus with 3 segments, 1 st segment as long as 3 rd segment, 2 nd segment shortest; 1 st segment with 5 setae, with small dorsal pit with sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 2.2x as long as wide, neck slightly shorter than wide, longest setae longer than width of flagellomere. Thorax. Brown; setae pale. Anterior pronotum with 5 setae. Proepisternum with 8 setae. Scutellum with 2 long and some short and fine setae. Wing. Fumose. Length 1.7 mm. Width/length 0.45. Anal lobe small. Veins distinct, except for stM. c/w 0.75. R1/R not detectable in the specimen studied. stM shorter than fork of M. bM and r-m subequal in length, stCuA shortest. bM and r-m non-setose. Halter yellow. Legs. Brown; setae pale. Fore tibial organ forming large patch of many setae in demarcated depression. Fore tibial spur slightly shorter than apical width of tibia. Abdomen. Pale brown; setae pale and moderately long. Hypopygium (Fig. 4B). Brown, like abdomen. Intergonocoxal area rather long, with short setose lobe. Gonocoxa longer than gonostylus, slightly roundish laterally, with rather dense and fine setosity. Gonostylus (Fig. 6C) widest subbasally, narrowed towards apex, strongly impressed medially, densely setose apically, with strong and curved apical tooth; with 5 medial megasetae in apical half, megasetae slender, long and straight, oblique, the apicalmost (with sockets) shorter than the others, as long as apical tooth; with well-differentiated long whip-lash seta in basal third of gonostylus. Tegmen (Fig. 13A) much wider than long, smoothly curved and membraneous apically, straight laterally, sclerotized basolaterally, with small area bearing a few aedeagal teeth. Aedeagal apodeme moderately long. BIN. Unknown. Discussion. Lycoriella eurystylata sp. n. resembles L. taimyrensis sp. n. and L. tundrae sp. n. in having the tegmen smoothly curved apicolaterally, whereas L. acutostylia Mohrig & Menzel, 1990 [described in Menzel et al. (1990)], L. jakovlevi sp. n. and L. kinbasketi sp. n. have the tegmen distinctly angled apicolaterally (Fig. 13). L. eurystylata differs from L. taimyrensis and L. tundrae in having the tegmen very short, strongly sclerotized basolaterally, semicircular apically and without tooth-like structures, whereas the other two have their tegmen only slightly sclerotized laterally, less curved apically and with tooth-like structures. Furthermore, L. eurystylata has five, L. tundrae four and L. taimyrensis eight to nine gonostylar megasetae and the fore tibial organ of L. eurystylata is more distinctly demarcated than that of L. taimyrensis and L. tundrae. L. eurystylata is similar to L. acutostylia, L. jakovlevi and L. kinbasketi in having rather long antennal flagellomeres (4 th flagellomere 2.1–2.3 times as long as wide), whereas L. taimyrensis and L. tundrae have shorter flagellomeres (4 th flagellomere 1.4–1.6 times as long as wide). To distinguish L. taimyrensis and L. tundrae, see under the former, and to distinguish L. acutostylia, L. jakovlevi and L. kinbasketi, see under L. jakovlevi sp. n. Etymology. The name is derived from the Greek words eurys, broad, and stylos, style, referring to the thick gonostylus of the male hypopygium.Published as part of Menzel, Frank & Vilkamaa, Pekka, 2021, New species and records of Lycoriella Frey (Diptera, Sciaridae) from the Holarctic region, pp. 501-530 in Zootaxa 5072 (6) on pages 507-509, DOI: 10.11646/zootaxa.5072.6.1, http://zenodo.org/record/575154

BIN. BOLD:ABA5288. Discussion. The species was described from one female from Novaya Zemlya by Holmgren (1883) and later described again based on some males and females from Greenland as Sciara glacialis (Lundbeck 1898) and from Spitsbergen as Sciara permutata (Lundbeck 1900). The species was redescribed with a list of literature, synonyms and combinations by Menzel & Mohrig (2000). Trichocoelina vitticollis (Holmgren) can be distinguished from all other species of the genus by its very large, setose intergonocoxal lobe of hypopygium and in having the gonostylus with a group of slender, oblique medial megasetae.

BIN. BOLD:ABA5288. Discussion. The species was described from one female from Novaya Zemlya by Holmgren (1883) and later described again based on some males and females from Greenland as Sciara glacialis (Lundbeck 1898) and from Spitsbergen as Sciara permutata (Lundbeck 1900). The species was redescribed with a list of literature, synonyms and combinations by Menzel & Mohrig (2000). Trichocoelina vitticollis (Holmgren) can be distinguished from all other species of the genus by its very large, setose intergonocoxal lobe of hypopygium and in having the gonostylus with a group of slender, oblique medial megasetae.

Lycoriella excavata Menzel & Vilkamaa 2021, sp. n.
No full textLycoriella excavata sp. n. Figs 2B, 3D, 12B Material studied. Holotype male. USA, Colorado, Laramer Co., Pinewood Springs, 40.2677°N, 105.3678°W, Malaise trap, 26.VII–7.IX.2014, S. & B. Fitzgerald (in MZH, http://id.luomus.fi/GE.1811). Description. Male. Head. Face and antenna concolorous brown, maxillary palpus pale brown. Eye bridge 1–2 facets wide. Face with 27 setae. Clypeus with 1 seta. Maxillary palpus with 3 segments, 1 st segment longer than 3 rd segment, 2 nd segment shortest; 1 st segment with 3 setae, with deep dorsal pit with sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 2.8x as long as wide, neck slightly longer than wide, longest setae longer than width of flagellomere. Thorax. Brown; setae pale. Anterior pronotum with 9 setae. Proepisternum with 10 setae. Scutellum with 2 moderately long and some short and fine setae. Wing. Fumose. Length 1.9 mm. Width/length 0.40. Anal lobe small. Veins distinct, except for stM. c/w 0.65. R1/R 0.75. stM longer than fork of M. bM as long as r-m, stCuA shortest. bM and r-m non-setose. Halter yellow. Legs. Pale brown; setae pale. Fore tibial organ forming large patch of setae in demarcated depression. Fore tibial spur longer than apical width of tibia. Abdomen. Pale brown; setae pale, short and weak. Hypopygium (Fig. 2B). Brown, like abdomen. Intergonocoxal area moderately long, with semicircular setose lobe. Gonocoxa narrow and long, longer than gonostylus, with sparse, rather short setosity. Gonostylus (Fig. 3D) widest subapically, slightly narrowed towards apex, deeply excavated dorsally; densely setose apically, with long and narrow apical tooth, with 1 subapical and 7–8 medial megasetae on ventral margin of apical half of gonostylus; with long whip-lash seta in middle. Tegmen (Fig. 12B) longer than wide, slightly notched apically, weakly sclerotized laterally, with area of minute teeth apicoventrally, with area of small aedeagal teeth. Aedeagal apodeme moderately long. BIN. Unknown. Discussion. Lycoriella excavata sp. n. with its subapically widened, lobe-shaped gonostyli resembles Lycoriella piristylata Vilkamaa, Hippa & Heller, 2013, which has (in contrast to the original description) also a palpal sensory pit and therefore belongs to Lycoriella Frey. In contrast to Lycoriella excavata sp. n., in L. piristylata a long whiplash seta is missing, the intercoxal lobe is small (or absent in some specimens), the apical tooth is significantly shorter or completely reduced and the tegmen is short and trapezoidal (Vilkamaa et al. 2013: fig. 3A–C). Lycoriella excavata sp. n. (Fig. 2B) also differs from this species in its ventrally enlarged lobe-shaped gonostylus with a very deep dorsal excavation, all medial megasetae of the gonostylus on its ventral margin, and its tegmen with apicolateral teeth. Apicolateral teeth of the tegmen are currently known only in Lycoriella taimyrensis described here (Fig. 13E), in some species of angustostylata species group in Bradysia Winnertz, 1867 (Menzel & Heller 2005; Mohrig 2016), as well in Odontosciara Rübsaamen, 1908 (Mohrig 2003). Etymology. The name is a Latin adjective, excavata, meaning hollowed, and refers to the strongly hollowed gonostylus.Published as part of Menzel, Frank & Vilkamaa, Pekka, 2021, New species and records of Lycoriella Frey (Diptera, Sciaridae) from the Holarctic region, pp. 501-530 in Zootaxa 5072 (6) on pages 509-510, DOI: 10.11646/zootaxa.5072.6.1, http://zenodo.org/record/575154
