Diagnosis. The species is characterized by evenly curved styles ( Figs 32A, B ) and the shiny black aedeagus ( Figs 31A–D ) with robust thorns on its ventral side and high socle, features that it shares with D. rusaevi Kusnezov, 1928 and D. medvedevi Logvinenko, 1961 . It is distinguished from the first species by the (in ventral view) distinctly widened aedeagus base, from the latter by the stouter and wider aedeagus shaft (ventral view). The position of the style denticle ( Figs 32A, B ) is approximately at mid-length, in the other two species not far from the apex. The female pregenital sternite ( Fig. 34A ) displays a strongly protruding, roughly semicircular hind margin without distinct median notch (tongue-shaped in D. rusaevi , provided with deep incision in D. medvedevi ).

Fifth instar. The only examined (parasitized) nymph (fifth instar; Fig. 30B, C ) is dark brown with little extended light areas in the middle of the apex of abdomen and laterally on tergite IV.

Distribution ( Figs 57 , 60B ). In Italy, the species is known only from the northern part: It was collected by R. Remane in Trentino-Alto Adige and Lombardy. More recently, the species was found by the authors in Emilia-Romagna and Friuli-Venezia Giulia.

The species is present from North Italy, eastern Central and Southeast Europe, until the East Palearctic region ( Kyrgyzstan, China). We examined specimens from Bosnia and Herzegovina, Czech Republic, Italy, Montenegro, Russia (Altai), Turkey ( Anatolia), and Ukraine. In addition, there are records from China: Xinjiang ( Duan & Zhang, 2012); Greece? ( Drosopoulos et al., 1986, as D. cf. concors ); Hungary ( Horváth, 1903b); Kazakhstan ( Mitjaev, 1971, as D. concors dzhungarica); Kyrgyzstan ( Dlabola, 1961); Poland ( Dworakowska, 1968); Russia: European part ( Emeljanov, 1964); Slovenia ( Horváth, 1903b) (as southern Austria [Tolmein], see remarks); Turkey: Black Sea Region ( Zeybekoğlu, 1998); Uzbekistan ( Dubovsky, 1966).

In Servadei’s catalogue, the species is recorded for Friuli-Venezia Giulia. Servadei refers to Horváth (1903b, reported by Metcalf 1967), but this author indicates “Tolmein” (Tolmin) as locality, in those times in Southern Austria, but nowadays in Slovenia (and not in Friuli-Venezia Giulia). Apparently, there are no records for the present Austrian territory.

Ecology. The species was found on dry lowland pastures ( Italy), but prevalently on mountain pastures and meadows until more than 1600 m ( Italy, Montenegro).

Phenology. We studied specimens collected from the middle of June until the beginning of September.
