description: <i>Melanagromyza asymmetrica</i> Guglya, sp. n. (figs 11 <i>–</i> 18) <b>Type material</b>. Holotype Ơ: Ukraine: Kharkiv Region, near Petrivske (49°10ʹ N, 36°58ʹ E), 10.05.2014, 15.00, motley grass between coniferous and deciduous forest (No &amp;Ncy;-78) (Guglya) (dissected). Paratypes: Kharkiv Region, 1 Ơ, 1 &amp;female;, same locality, 11.05.2014, 15.00, flood land (No &amp;Ncy;-79, H-80) (Guglya); 2 Ơ, near Haidary (49°37ʹ N, 36°19ʹ E), 04.06.2011, 18.00, motley grass in a gully (No &amp;Ncy;-81, H-82) (Guglya) (all dissected). D e s c r i p t i o n. Head (figs 11 <i>–</i> 12). Orbit not projected above eye in profile; 2–3 orb s, 3 fr s (all strong), all specimens in type series with different numbers of orb s, more, often two left and three right; frorb sta in two rows, mainly reclinate and lateroclinate, with a few proclinate at level of lunule; orbit wide and shining (frontal view); frontal carina not differentiated; lunule slightly shining, high, rounded dorsally, with distinct furrow; ocellar triangle matt, narrow, reaching level of 3rd orb s, with very slight contours; frons matt; vibrissa larger than sbvb s; maximum height of eye 5× as high as gena; gena angular; 1st flagellomere round (lateral view), covered with white elongated hairs. Wing (fig. 16) hyaline; costal vein black, other veins brown; costa reaching M 1; last section of CuA 1 0.8× as long as penultimate; costal sections 2-4 in the ratio of 4.18: 1.12: 1.00; calypter yellowish, margin yellow; hairs of fringe rather long, yellowish. Wing length 2.95 (Ơ) to 3.2 (&amp;female;) mm. Mesonotum weakly shining, blackish-grey (dorsal view); scutellum more matt; 2 dc; ac black, in 10 irregular rows at level of 2nd dc; halters and legs shining black. Mesonotum and scutellum of female more shining with coppery undertone. Male terminalia (figs 13 <i>–</i> 15). Epandrium covered with long hairs; cerci with long hairs only; inner surface of surstylus covered with numerous small prensisetae; hypandrium Y- shaped, with acute apex; ejaculatory apodeme shorter than phallus; phallus 0.20 mm long, distiphallus complex elongated, oval, acute concaved anteriorly (ventral view); mesophallus of medium length, slightly concaved apically; anterior part and arms of basiphallus strongly sclerotized; both arms are connected by weakly sclerotized crosspiece posteriorly. Female terminalia (figs 17 <i>–</i> 18) Both spermathecae identical, dark brown, suboval, slightly concaved basally; egg guide 5.4× as long as spermatheca; egg guide narrow, 5.3× as long as its maximum width, acute apically; medial membrane covered with numerous small brown teeth, with one row of somewhat larger teeth located apically along dorsal margin. B i o n o m i c s. One generation was recorded in May–June. Host plant unknown. Diagnosis. The new species is superficially similar to <i>Melanagromyza albocilia</i> Hendel, 1931 in having bright whitish-yellow calypter, margin and fringe, last section of CuA 1 0.8× as long as penultimate, costal vein black, other veins beije; arms of basiphallus connected by crosspiece posteriorly, differing by having blackish-grey slightly shining mesonotum, 3 orb s; frorb sta thick, lateroclinate, distiphallus narrowing in posterior third, mesophallus slightly concaved apically (in <i>M. albocilia</i>, body black with yellowish-green tinge and strongly shining mesonotum, 2 orb s, frorb sta sparse, inclinate and reclinate; distiphallus narrowing in posterior half; mesophallus rounded apically). E t y m o l o g y. The species name reflects asymmertical position of orb s and fr s in the type series.
