Description. Head ( figs 21, 22 , 24 ). Orbit slightly projected above eye in profile, narrow, slightly shining, with shining areolae of setae, without clear contour (anterior view); 2 orb s, 2 fr s; frorb sta sparse, reclinate; frons matt, without dorsocentral suture; lunule low and wide, flattened dorsally, with wide furrow from ptilinal fissure to facial carina; facial carina bulbous, strongly projected above level of lunule, with deep but narrow furrow; ocellar triangle reaching to the level of lower orb s; maximum height of eye 4.6× maximum height of gena; vibrissal fasciculus strong, long, slightly curved dorsally in male; long vibrissa presents in female.

Wing ( fig 25 ) greyish. Costa reaching M 1; last section of CuA 1 slightly shorter than penultimate; calypter brown, fringe and margin black. Wing length 2.1 mm.

Mesonotum black, shining; scutellum less shining (dorsal view); 2 dc; acr in 6–8 rows at level of 2 nd dc; halter and legs black.

Male genitalia ( figs 26–30 ). Phallus typical for the genus, 0.34 mm length. Distiphallus 1.13× as long as basiphallus. Distiphallus subovate (ventral view), gradualy narrowing posteriorly and sharply narrowing and curved to left anteriorly (ventral view). Mesophallus thickened, shifted to the left (ventral view). Basiphallus wide, massive, with sclerites weakly sclerotized. Hypandrium V-shaped, with narrow slightly broadened arms; hypandrial apodeme short, narrow. Ejaculatory apodeme narrow, tapered basally, with darker apical half; its length 2.3× width.

F e m a l e t e r m i n a l i a ( fig. 22 ). Both spermathecae identical, dark brown, its width 1.45× maximum height; basal collar strongly sclerotized, ring-shaped, widening to base of spermatheca; internal duct invagination reaching 0.65 height of spermatheca. Blade of hypogynium 1.15× as long as proctiger with cerci. Blade of hypogynium acute apically, denticles on outer margin small, sparce and blunt, scarcely visible, directed apically, inner margin and membrane without scales.

Diagnosis. Uniformly black species with greyish wings and brown calypter. External morphology and shape of the male genitalia are most similar to those of Ophiomyia campanularum Stary, 1930 , but in the new species, the facial bulb wider and flat, without a furrow, the distiphallus is not narrowed and curved proximally, and the basiphallus is slightly longer than the distiphallus.

The new species can be integrated to the Key of Ophiomyia of Ukraine ( Guglya, 2014) as follows:

34. Lunule slightly rounded; vibrissal fasciculus uniformly dark. Distiphallus narrowing anteriorly and posteriorly. Mesophallus posteriorly not reaching sclerites of basiphallus............................................... 35

― Upper margin of lunule flat and tapered in the centre; vibrissal fasciculus straight, directed slightly upwards, white at the end (see Guglya, 2013: figs 33, 34 ). Distiphallus narrow, rectangular anteriorly and triangular posteriorly, mesophallus posteriorly reaching sclerites of basiphallus (ventral view). Basiphallus 1.28× as long as distiphallus (see Guglya, 2013: figs 35, 36 ) dark ........................................... ............................................................................................................... O. fasciculusalba Guglya, 2013

35. Facial carina bulbous, strongly projected above level of lunule, with deep but narrow furrow, that spread on lunula and expands towards ptilinal fissure ( fig. 21 ) Distiphallus with strictly narrowing and curved distal part and oval-triangular proximal part (ventral view), that posteriorly as long as endophallus (lateral view) ( figs 26, 27 ) ................................................................................ O. mukhorytsa sp. n.

― Facial carina flattened, without any furrow (see Guglya, 2013: figs 86, 87). Distiphallus with small oval distal part and elongated triangular proximal part (ventral view), that posteriorly distinctly longer that endophallus (lateral view) (see Guglya, 2013: figs 88, 89)........................ O. senecionina Hering, 1944

D i s t r i b u t i o n. Transcarpathia and Ivano-Frankivsk Region of Ukraine.

E t y m o l o g y. “Mukhorytsa” — local trivial name of all tiny black flies in Rakhiv district of Transcarpathia, where the new species was firstly collected.
