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.

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 .
