Known from Edirne and Kırklareli provinces in Turkey ( Karabaġ et al., 1971; see Material examined) ( Fig. 156 ).

Description. Male (neotype): Male: Head large, 1.3 times higher than wide in frontal view; head large, wider than anterior width of pronotum; eye very small almost as large as antennal foramen. Lateral carinae of pronotum ( Figs. 1, 2 , 118, 119 ) very distinct except posterior part of metazona, blunt, not sharply raised; prozona distinctly depressed; metazona raised, with a very distinct 2 tubercular folds; anterior margin of pronotum slightly concave, posterior margin with 3 small incision, of which middle one more distinct; prozona 1.2 times narrower than metazona in dorsal view; anterior margin of prozona and metazona raised; the highest part of pronotum in prozona, 1.1 times higher than metazona in lateral view; pronotum 1.8 times longer than its height ( Figs. 1, 2 , 118, 119 ). Tegmina brachypterous, fully concealed under pronotum. Femora sometimes with several ventral spines apically; hind tibia with 2 dorsal and 4 ventral spurs apically; Prosternum with 2 moderate size spines but its length variable; lobes of meso and metasternnae collar-like. Subgenital plate ( Fig. 3 ) 1.3 times wider than long, without styli, with 2 lateral carinae, posterior margin almost straight between the end of lateral carinae. Cercus ( Fig. 4 ) small and short in dorsal view; apex rounded; inner tooth strongly recurved, pointed with a small denticle; ventral view much longer ( Fig. 5 ); basal lobe small and high. Titillator ( Figs. 6, 7 ) with very short basal and apical arms; apical arms distinctly diverged but distal part straight, apex pointed and slightly curved outwards; basal arms distinctly upcurved, but in some specimens less curved; bridge between left and right arms very long; in lateral view ( Fig. 7 ) apical arm straight, apex curved towards the anterior.

Female: Head as in male, but slightly narrower. Pronotum ( Figs. 8, 9 , 120, 121 ) with more compressed and shorter metazona than male; 1.7 times longer than its height; pronotal pit in dorsal view wide and shallow; paranota in lateral view quite low; anterior part of prozona and metazona raised in lateral view ( Figs. 9 , 120 ). Tegmina and legs as in male. Subgenital plate ( Fig. 10 ) wide at base and strongly narrowed to apex, with a large and deep median incision at apex. Cercus ( Fig. 11 ) conical, short and broad, 1.3 times longer than wide, pointed with a sharp tooth; basal lobe small and high. Ovipositor ( Figs. 12 , 120, 121 ) very long, 1.5 times longer than hind femur; ventral valve smooth without any apical tooth; upper and lower valves not diverged at apex; basal projecting of ventral valve ( Fig. 13 ) narrow along its length, rounded at apex.

Color: Body metallic black except some small light spots. Head black, basal part of mandibles and eyes brownish cream. Pronotum fully black. Femora black with some light spots in male, brownish cream with many black spots in female. Tibia cream with black spots, its spines fully blackened including basal parts. Tarsi dark cream; apical part of each segment blackened. Dorsal surface of abdomen black; typically posterior margin of each abdominal tergite with a row of small cream spots. Lateral surface of mesonotum, metanotum and abdomen cream to brownish cream in male, lighter in female. Abdominal sternites brown to black but in some specimens slightly lighter. Basal part of ovipositor dark cream, apical part darkened to black. Although lateral sides of body in some specimens lighter, the black coloration of this species is quite stable and characteristic especially in dorsal view.

Measurements (mm): Length of body: male 47.1–52.7, female 48.2–58.3; pronotum: male 15–17.5, female 14.5–17; hind femur: male 18.3–20, female 19.5–23; ovipositor: 29–31.5.

Diagnosis. This species is unique in the genus. It is easily separated from the others by the shape of titillator with its very short basal and apical arms, the male cercus with boadly rounded apex and strongly recurved inner tooth, the female subgenital plate with strongly narrowed apex and a large median incision, the long ovipositor without apical teeth, the shape of basal projecting of ventral valve with rounded apex and the typical coloration. This species shares two female characters with Bradyporus karabagi sp. n. Upper and lower valves of ovipositor not diverged at apex and the basal projecting of ventral valve of ovipositor rounded in both species. On the other hand all the other characters are very different including their distribution.

Remarks. The type is lost ( Harz, 1969). Therefore a male neotype is designated from the European Turkey.
