Diagnosis.

Male (Fig. 4 A – M). Body length 1.9–2.4 mm; wing length 1.9–2.5 mm. Female (Fig. 5 A – L). Body length 2.1–2.9 mm; wing length 2.2–2.8 mm. Fronto-orbital plate light brown or dark brown between two ors. Inner vertical setae surrounded by yellow coloration at base. First flagellomere brownish black, distinctly angulate at anterodistal corner; arista thickened on basal 1 / 5. Gena ~ 2 / 3 height of eye; genal grooves distinct on anterior 1 / 2 of gena. Mesonotum and scutellum shiny black, acr in two irregular rows (Fig. 4 D), supra-alar setae on dark brown background. Anepisternum black except for yellow dorsal and posterior margin. Katepisternum black. Legs yellow with tibiae and tarsi brown. Male genitalia (Fig. 4 G – M): distiphallus S-shaped with distal tubules parallel, ~ 2.5 × length of mesophallus; terminal processes short, pale brown. Female terminalia (Fig. 5 H – L): spermathecae circular and truncated at basal 1 / 4, internal duct invagination 1 / 4 as deep as height of spermathecae.

Distribution.

Palaearctic: Austria, Belgium, Bulgaria (Černý et al. 2022), China (Xinjiang, Qinghai *), Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Japan, Latvia, Lithuania, Montenegro (Spasić 1996), Netherlands, Norway, Poland, Portugal (Černý et al. 2018), Romania, Russia, Slovakia, Spain, Sweden, Tajikistan, The United Kingdom, Turkey, Ukraine, Uzbekistan (Soós and Papp 1984).

Remarks.

The new species is similar to C. (C.) denticornis (Panzer, 1806) from the Palaearctic, Oriental and Afrotropical regions in the first flagellomere brownish black with a spine at dorsal corner, but it can be separated from the latter by mesonotum and scutellum being shiny black; acr being in two irregular rows; the distiphallus (Fig. 4 G, J) having trumpet-shaped terminal processes less pronounced than C. (C.) denticornis (Spencer 1976: fig. 319). In C. (C.) denticornis, the mesonotum is matt grayish black or yellow centrally and adjoining the scutellum; the scutellum is either black or variably yellow; the acr rows are absent.
