Černý 2010 // Holotype’ (NMPC). Loc. No. 9. Terminalia dissected, mounted on the same pin (medium: glycerine and gum resin).   
 Description (male, holotype). Head black, ocellar triangle, fronto-orbital plate and frontal vitta matt black. Antenna and palpi brown. Thorax greyish black, subshining. Notopleuron leathery brown, anepisternum along upper and hind margin only narrowly ochre brown. Wing hyaline, base of wing ochre brown and veins brown. Calypters grey, their margin and fringe blackish brown. Knob of halteres blackish brown, stem ochre brown. Legs blackish brown. Abdomen blackish brown.   
Head (Figs. 34–35). Frons broad, about as wide as 1.88 width of eye at level of anterior ocellus, slightly tapering toward lunule. Ocellar triangle large, its tip reaching level of lower ors seta. Fronto-orbital plate narrow, each about 0.14 width of frons, not prominent in front of eyes in profile. The antennae are separated by a narrow keel reaching only 0.6 scape width. Two strong ors setae reclinate and 2 strong ori setae inclinate and reclinate. Orbital setulae sparse and short, reclinate. Gena narrow, reaching 0.14 height of eye, parafacialia narrow. Vibrissal corner forming angle of approximate 65°, vibrissal fasciculus long, with tip curved to antennae. Eye bare.  
 Scutum with 0+2 dc setae, 1 st dc seta inserted in sa setae line.Acrostichal setulae in 8 rows, sparse setulae reaching to 2 nd setae line. Postpronotal lobe with 1 hu seta and 5–6 setulae. One stpl seta and 8–10 setulae present. Scutellum broader than long, index 2.33: 1.00. All usual setae present: 1 oc, 1 pvt, 1 vte, 1 vti, 1 ppl, 1+1 ntp, 1 mspl, 1 sa, 1 prs, 1 bs, 1 as.   
 Wing (Fig. 33) 2.08 mm long. Costa reaching end of vein M 1, costal sections 2–4 in the ratio of 5.31: 1.13: 1.00. Last section of CuA 1 shorter, only as long as 0.84 length of preceding section. Distance between R-M and DM-Cu as long as 0.93 length of DM-Cu.   
Legs. Mid tibiae without pd setae.  
 Abdomen oval, length of 5 th and 6 th tergites equal. Male terminalia (Figs. 36–41): epandrium (Fig. 40) 1.23 times broader than high. Surstylus with group of short and blunt spines on inner surface. Cerci narrow, reaching 0.43 height of epandrium. Phallus (Figs. 36–37) about 0.5 length of phallapodeme, distiphallus asymmetrical, with distal longitudinal fissure, mesophallus oval. Basiphallus slightly pigmented, with long, basally broadly fused arms. Ejaculatory apodeme (Figs. 38–39) about as long as phallus. Hypandrium (Fig. 41) with short hypandrial apodeme and basally dilated arms.   
Female. Unknown.  
Body length 2.38 mm.  
 Differential diagnosis. Ophiomyia krousianica sp. nov. is very similar to the European O. hieracii Spencer, 1964, characterized by the following features: the width of the frons is only 1.5 times broader than the eye; the ocellar triangle and the fronto-orbital plate are black, weakly shining; the calypters are grey, their margin and fringe are black. Male terminalia of both species are markedly different.   
 Etymology. The species is named after the type locality, Krousia Mts. in North Greece.   
 Bionomics. Unknown.   
 Distribution. Greece: Kerkini. Hitherto known only from the type locality.
