Description. Head (fi g s 31, 32). Head black and orange. Orbit black, strongly projected above eye in profi l e at level of lunulae, narrow, matt, without clear contour (anterior view); 2 orb s, 2 fr s; frorb sta sparse, short, reclinate; frons dirty-orange, matt; lunule orange, rounded, with narrow furrow from ptilinal fi s sure to facial carina; facial carina very narrow, but distinctly projected; gena dirty-orange; ocellar triangle black, shining, reaching to the level of lower orb s; maximum height of eye 2.75× maximum height of gena.
Wing (fig. 33). Wing beige. Costa reaching M 1; last section of CuA 1 0.65× as long as penultimate; calypter and margin white to beige, fringe slightly darker, ochrous. Wing length 2.5 mm.
M e s o n o t u m a n d s c u t e l l u m black, moderatyly shining, scutellum shining less (dorsal view); 3+0 dc, fir st very strong, third very weak (0.5× as long as firs t); acr in 5 rows at level of 3 rd dc; halter white, legs black.
Male genitalia (fig s 34–38). Phallus is typical of those seen among grass-feeding Agromyza. Sclerites (arms) of basiphallus relatively long, more than twice as long as mesophallus-distiphallus complex, wide and rounded anteriorly. Distiphallus blunt and slightly widening anteriorly, its length equal to the length of mesophallus (lateral view). Ejaculatory apodeme elongated, narrow triangular; length of ejaculatory bulb equal to the apodeme. Phallus 0.4 mm length, one specimen from Kalvaria with length of phallus 0.35 mm.
F e m a l e t e r m i n a l i a (fig. 39). Both spermathecae dark brown, trapezoidal, elongated with sharp triangular invagination apically. Internal duct invagination cylindrical, well sclerotized, with narrow collar of spermathecal duct near capsule base. One always larger than other. Capsule of the smallest curved at a 45°angle.
Diagnosis. Structure of male terminalia of the new species is similar to those A. lucida and A. megalopsis, but those of the new species diff er in the shape, relative size and orientation of the basiphallus and mesophallus-acrophallus complex, the quantity and localization of setae on surstyli, and the shape of the basal lobes of the hypandrium and ejaculatory apodeme (see table 1 below).
The new species can be integrated to the Key of Agromyza of Hungary (Papp & Černý, 2015) as follows:
0. Presutural dc pair absent (figs 31–39).............................................................................. A. paralucida sp. n. ― 1 or 2 pairs of presutural dc present........................................................................................................1
D i s t r i b u t i o n. Transcarpathia and Kharkiv Region of Ukraine and Belgorod Region of Russia (fig. 41).
H o s t s p e c i a l i z a t i o n. Host plant unknown, the structure of the male and female terminalia associates it with grass-feeding species.
Etymology. The name of new species indicates on the similarity with A. lucida.
