Face brown, antenna slightly darker brown, maxillary palpus yellowish. Eye bridge 2 facets wide. Face with 17–28 fine setae. Clypeus with 2–3 setae. Maxillary palpus with 3 segments, 1 st segment either longer or shorter than 3 rd segment, 2 nd segment shortest; 1 st segment with 3–6 setae, with a dorsal patch of sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 2.3–2.6x 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 8–13 setae. Proepisternum with 10–13 setae. Scutellum with 3–4 longer and some short and fine setae. Wing . Fumose. Length 2.5–2.9 mm. Width/length 0.40. Anal lobe moderate. Veins distinct. c/w 0.60–0.85. R 1 /R 0.70–0.85. stM longer than fork of M. r-m and bM of variable lengths, bM non-setose, r-m with 2–4 setae. Halter yellow. Legs . Yellow, coxal setae pale. Fore tibial organ forming a large patch in depression. Fore tibial spur slightly longer than the tibial width. Abdomen . Pale brown, setae pale, fine and moderately long. Hypopygium (Fig. 12 B). Brown, as abdomen. Intergonocoxal area long, basally with strongly sclerotized medial stripe, with 2 distinct setose lobes (Fig. 17 B). Gonocoxa broad, as long as gonostylus, medial margin basally strongly curved, with short sparse setosity. Gonostylus (Fig. 13 D) long, apically truncate, strongly impressed; with short setosity, with a short dorsal apical tooth in subapical position, with 8–12 medial megasetae, megasetae long and slender, straight or slightly curved; with one long and 2–3 shorter whiplash setae basad of the megasetae. Tegmen longer than broad, conical, with sharp apicolateral corners, basolaterally broadened, apically and laterally sclerotized; aedeagal teeth not detectable in the specimens studied. Aedeagal apodeme long. BIN . Unknown. Discussion . See under Trichocoelina imitator sp. n. Etymology . The name is derived from the Latin words oricilla, small ear, and - fer , bearing, referring to the lateral lobes of the tegmen. : 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 40, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/4000553 : {"references": ["Heller, K., Vilkamaa, P. & Hippa, H.
