Description. Head (figs 10, 11, 18, 19). Orbit not projected above eye in profile, narrow, matt, without clear contour (anterior view); 2 orb s, 2 fr s; frorb sta sparse, reclinate; frons, orbits and ocellar triangle uniformly matt; frons with distinct dorsocentral suture; lunule rounded, with wide furrow from ptilinal fissure to facial carina; facial carina strongly projected above level of lunule, oval, in female 1.5× as wide as in male; ocellar triangle reaching to the level of upper fr s; maximum height of eye 7.5× maximum height of gena; vibrissal fasciculus long, gradually curved dorsally in male, long vibrissa presents in female.
W i n g (fig.17). Costa reaching M 1;last section of CuA 1 slightly shorter than penultimate; calypter grey, fringe and margin black. Length of wing 2.1 mm.
Mesonotum black, shining, with golden undertone; scutulum the same, but undertone stronger (dorsal view); 2 dc; acr in 8–9 rows at level of 2 nd dc; halter and legs black.
M a l e g e n i t a l i a (figs12–16).Phallus typical for the genus, 0.35mm length.Distiphallus massive orbed anteriorly and more narrow triangular posteriorly (ventral view), distiphallus posteriorly distinctly longer than mesophallus (lateral view). Mesophallus slightly curved basally and rather long, 0.7× as long as distiphallus. Basiphallus with narrow sclerites (arms), 1.4× as long as distiphallus (ventral view) (figs 12, 13). Ejaculatory apodeme moderately narrow (fig. 16). Hypandrium elongated with narrow broadened arms and hypandrial apodeme abducted and slightly curved laterally as in figs 14, 15.
F e m a l e t e r m i n a l i a (fig. 20). Both spermatheca identical, dark brown, wider than high, its width 1.5× as maximum height; internal duct invagination scarcely visible, reaching the top of spermathecae; blade of hypogynium and proctiger with cerci of the same length; blade of hypogynium rounded apically, denticles of outer margin small, scarcely visible, directed apically, inner margin and membrane without scales.
Diagnosis. External morphology of the new species is similar to that of other Ophiomyia species with fasciculus that cannot be reliably identificated without male dissection. The male terminalia are distinct in that the shape of phallus resenbles that of O. moravica Černý, 1994, but in O. moravica there is a distinct gap between the mesophallus and the posterior half of the distiphallus (in lateral view), and the anterior part of the distiphallus 1.5× as long as the posterior.
The new species can be integrated to the Key of Ophiomyia of Ukraine (Guglya, 2014) as follows:
30a. Ocellar triangle large, reaching to the level of upper fr s; facial carina oval, without any invaginations or furrows (figs 10, 18). Distiphallus with massive orbed distal part and more narrow triangular proximal part (ventral view), that posteriorly distinctly longer that endophallus (lateral view) (figs 12, 13)............ ................................................................................................................................................ O. kireshiensis sp. n.
― Ocellar triangle of medium size, reaching to the level of lower orb s; facial carina with invagination or furrow. Distiphallus of another shape .................................................................................................. 31
D i s t r i b u t i o n. Transcarpathia and Vinnytsa Region of Ukraine (fig. 40).
E t y m o l o g y. The species is named after its type locality.
