Bembecia albanensis ( Rebel, 1918)

4 exuviae— 3 males, 1 female ( France 2000–2004).

Length and width: 13.4–15.7× 3.1–3.7 mm (average: 14.5× 3.4 mm).

Area of head projection blade short and fairly sharply rounded in dorsal view, its length is slightly shorter than half of its width. Depressions of frons wrinkled, fairly deep and frons central ridge strong. Frontal setae situated distinctly behind level of lateral angles of frons in dorsal view ( Fig. 3a ). Plate of head projection blade, rounded and not distinctly curved in lateral view, dark margin narrow. Lateral depression on head wide and rounded ventrocaudally ( Fig. 3b ). Distance between clypeal setae C1 2 from 2.5 to 3× greater than distance between C1 2 and Cl 1. Labrum truncate for a greater distance and with concave sides ( Fig. 3c ). Cremaster relatively roundly pointed at end, anal suture distinctly shorter than cremaster in male, approximately equal in length to anal suture in female ( Fig. 3d ).

Diagnosis. Pupa of Bembecia albanensis similar to B. psoraleae . Plate of head projection blade, rounded and not distinctly curved in lateral view, in B. psoraleae distinctly curved.

Biology. Usually univoltine. Host plants—Fabaceae: Bituminaria bituminosa (L.) C.H.Stirt., Hedysarum coronarium L., Ononis arvensis L., O. repens L., O. spinosa L.

Distribution. Western, central, eastern and southern Europe, southern Russia, Turkey ( Špatenka et al. 1999).
