The following museum and collection acronyms are used in the text:
Medium-sized (wing length 4–5 mm) species within
Thorax in general deep dark brown to black, mostly shiny. Prescutum and scutum mostly black, shiny, with slight greyish pruinosity and slightly paler laterally, yellowed lateral to prescutal pit and around wing base, pale yellow on paratergite anteriorly. Scutellum and postscutellum shiny black, paler laterally. Pleuron shiny black throughout. Wing length 5.0 mm. Wing membrane slightly infuscate; venation as for genus. Halter yellowish brown. Legs yellowish brown, with tips of femora and tarsi darkened.
Abdomen deep dark brown to black. Male terminalia (Figs
Male terminalia.
The new species is named in honour of its collector, Dr. Jindřich Roháček (Silesian Museum, Opava, Czech Republic), a world-famous specialist of
The new species differs from its similar congeners by details in the structure of the male terminalia, especially its swollen aedeagus and very long aedeagal plate.
