Maxillary palpus with 3 segments, 1 st and 3 rd segments subequal in length, 2 nd segment shortest; 1 st segment with 2–5 setae, with deep dorsal pit with sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 1.5–1.6x as long as wide, neck shorter than wide, longest setae shorter than width of flagellomere. Thorax . Brown; setae pale.Anterior pronotum with 5–7 setae. Proepisternum with 5–6 setae. Scutellum with 2 moderately long and some short and fine setae. Wing . Fumose. Length 1.4–1.5 mm.

Halter yellow. Legs . Pale brown; setae pale. Fore tibial organ forming small indistinct patch of setae in poorly demarcated depression. Fore tibial spur shorter than apical width of tibia. Abdomen . Pale brown; setae pale and short. Hypopygium (Fig. 10B). Brown, like abdomen. Intergonocoxal area (Fig. 14D) moderately long, with wide setose lobe. Gonocoxa wide, longer than gonostylus, with sparse, rather long and fine setosity. Gonostylus (Fig. 11B) widest basally, strongly tapered towards apex, slightly impressed medially; densely setose apically, with strong apical tooth, with 4–5 long and narrow medial megasetae on basal bodies on apical third of gonostylus; with long whip-lash seta in the middle. Tegmen (Fig. 13F) about as long as wide, smoothly curved apically and laterally, weakly sclerotized, with some small teeth basolaterally, apodemes strongly sclerotized, with area of small aedeagal teeth. Aedeagal apodeme short and strong. BIN . Unknown. Discussion . See under Lycoriella eurystylata sp. n. , L. jakovlevi sp. n. and L. taimyrensis sp. n. Etymology .
