DIAGNOSIS

A species of the assimilis -group. Pedicel with apical ventral seta as long as pedicel. Proepisternum shiny black, no upturned seta above fore coXa. Fore coXa yellow, but base brown. Mid and hind coXae, and rest of the legs brownish to black eXcept base of fore femur yellowish. Vein R 4+5 and M 1 diverging towards wing tip. Haltere black.

Mid femur anteriorly with ribs; with a row of short dark posteroventral setae half as long as femur is wide. Mid tibia with a double row of ventral spinules on apical ¾ and short black apical spine. Hind femur on basal ¾ with long yellowish brown posteroventral setae as long as femur is wide.

MATERIAL EXAMINED

BULGARIA: 1 ♂, 5 km W of Smolyan glade, sw, 41.569, 24.632, alt. 1260m, 14-17 June 2019, (BartÁk & Kubík leg.; in coll. BartÁk). Male terminalia dissected (MS reference Bul 2), in coll. RBINS GoogleMaps

DISCUSSION

The presence of two black sQuamiform setulae on the inside of the apeX of the left surstylus is a good character and was observed in specimens from Czech Republic and northern Italy (rather pale in the latter). Their presence was not mentioned by either COLLIN (1961) nor CHVÁLA (1975). However, COLLIN (1961, Fig. 12a View Fig ) seems to have drawn two darker bristles on the apeX of the left cercus that might represent these bristles. Otherwise, the male genitalia do correspond in most details to the figure given by COLLIN (1961). The presence of ribs on the anterior side of the mid femur is to our knowledge not reported for D. assimilis . It seems unusual in the assimilis -group.

Although this species is rather common in western Europe only a single male was found here in Bulgaria.

DISTRIBUTION

Austria, Belgium, Croatia, Czechia, Estonia, Finland, Germany, Great Britain, Hungary, Italy, Macedonia, Norway, Portugal (Madeira), Norway, Poland, Russia Slovakia, Slovenia, Spain (Azores), Sweden, Switzerland, Ukraine (after SHAMSHEV, 2016).
