Trichocoelina brevicubitalis (Lengersdorf, 1926) comb. n. Literature. Sciara brevicubitalis Lengersdorf—Lengersdorf (1926): 6; Gerbachevskaja-Pavluchenko (1986): 61. Lycoria (Neosciara) brevicubitalis (Lengersdorf) — Lengersdorf (1928 –30): 61. Neosciara brevicubitalis (Lengersdorf) —? Lackschewitz (1934): 155; Soot-Ryen (1942): 77. Lycoriella (Hemineurina) brevicubitalis (Lengersdorf) — Frey (1942): 36; Menzel & Mohrig (2000): 408. Redescription. Female. Head. Dark brown. Eye bridge united, 2–3 facets wide. Maxillary palpus long, with 3 segments, all segments narrow, 1 st segment with 4 sharp setae, with a dorsal unbordered patch of sensilla. Scapus and pedicellus dark bown and roundish; antennal flagellomers missing in the specimen studied. Thorax. Postpronotum non-setose. Scutellum with 8 long and strong setae. Legs. Strong, with long tibial spurs; tibial spurs of mid and hind tibiae unequally long [one spur is about 1/4 shorter than the other]; tarsal claws without teeth. Wing. 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 ...
