No synonyms.

Diagnosis: Body length of both sexes is 8–12 mm, ovipositor length is 4.4–6.1 mm. Females with middle-sized ovipositor sheath 1.9–2.5× long as third tibia, with whitish apex 1.4–2.2× as long as third basitarsus. Head not elongated with a narrow occipital carina, finely punctate. Mesonotum with a relatively fine rugulose sculpture, shiny. Antesternal carina small.

Distribution: ( Fig. 195 ): European species. A very rare species of central Europe, occurring especially in Pannonian lowland. Recorded from the following countries: Austria, Croatia, Czech Republic, France, Greece + Crete, Hungary, Italy, Slovakia and Switzerland ( Ferrière 1946; Šedivý 1958; Madl 1988; 1989; Pagliano & Scaramozzino 2000; Žikić et al. 2014; Madl & Mitroiu 2019, and personal records).

Šedivý (1958; 1989) recorded this species only from the Czech Republic (Moravia). We are bringing the first record from Slovakia. One old undated male record from Lučenec was found in the collections of Oberösterreichisches Museum, Linz. There are only a few records. In the Czech Republic, it was recorded only in the south of Moravia in Mohelno and Brno-Bobrava, recently in Havraníky (Havranické vřesoviště heathland in Podyjí National Park) in 2011 ( Tab. 2).

Biology: Unknown.

Conservation: A species which was always very rare in the whole distribution area, where only a few records are known from the neighbouring countries. In the Czech Republic it is restricted to south Moravia with only one recent find, in Slovakia it is probably extinct. Males are difficult to identify and could be probably misidentified with other species. Red List Categories: CR—critically endangered ( Czech Republic), RE—regionally extinct ( Slovakia) ( Tab. 2).
