D e s c r i p t i o n. Head (fig. 61, 62, 65). Orbit narrow, matt, without clear contours (anterior view), strongly projected above eye in profile; 2 orb s, 2 fr s; frorb sta sparse, reclinate; frons matt; facial bulb flattened, moderately wide and rounded in lower part, 1.2 × as wide as base of antenna; lunule rounded, distinctly projected above level of frons; ocellar triangle matt, with clear contours, reaching the level of 2nd orb s; maximal height of eye 6.0 × maximal height of gena; gena slightly projected (in male) or not projected (in female) anteriorly (lateral view).

Wing. Costa ending between R 4+5 and M; last section of M 0.8 × as long as penultimate; calypter grey, fringe and margin dark greyish. Length of wing 2.9 mm.

Рис. 68–74. O. vimmeri Černý : 68, 69 — голова самца; 70 — фаллюс, латеральный вид; 71 — то же, вентральный вид; 72 — голова самки; 73 — левая лопасть восьмого стернита; 74 — сперматека. Масштабная линейка 0,1 мм.

Mesonotum black with greyish pruinosity (anterior view); 2 dc in male, 3 dc in female; ac 4 nearest to sctsctl sut and 6 at level of 2nd dc; halter and legs black.

Male genitalia (fig. 63, 64). Phallus 0.48 mm long. Phallus atypical for the genus, extremely elongated. Basiphallus with wide apical margin (ventral view), widely separated from distiphallus. Distiphallus ovate, with extremely elongated distal process that is apically bifid. Membrane thickly dotted. Endophallus reaching posterior margin of distiphallus.

Female terminalia (fig. 66, 67). Both spermathecae equal, oval, flattened apically, 0.5× as long as wide. Proximal and ventral margins of egg guide with small, well-marked teeth, directed posteriorly. Medial margin without any scales.

D i a g n o s i s. The shape of the gena of Ophiomyia vanyshai is similar to that of O. nasuta (fig. 33–34) and O. pinguis (fig. 44–45), but other characters (size and shape of facial keel, number and orientation of frorb sta, presence of orb s in male and strongly projecting orbits above eye in profile) are different. It can be easily recognized from Ukrainian congeners in having a lunule projecting above the frons in profile, the shape of the facial keel, an orbit strongly projected above the eye in profile, and with a costa ending between R 4+5 and M. The phallus is also uncommonly elongated, with the distance between the basiphallus and distiphallus complex as long as the basiphallus itself. The distiphallus also has spherical ventral apodeme, and it has a long, apically bifid process enclosed in a membranous structure.

D i s t r i b u t i o n. Eastern Ukraine (east of Kharkiv Region).

E t y m o l o g y. The species is named in honor of the author’s son, Vanyusha.
