Mesostenus kozlovi Kokujev, 1909

Mesostenus kozlovi Kokujev, 1909

Material examined: 1♀, IRAN, Sistan-o Baluchestan Province , Tamin (28°41′56″N, 61°10′15″E, 1933 m), Mal- aise trap, 01– 15.04.2016, leg.: N. Khajeh.

Distribution in Iran: Sistan-o Baluchestan Province.

Remarks: Examination of the type materials indicating this species is very similar to Mesostenus grammicus Gravenhorst, 1829 . Both species are thought to be mixed in the past or it is also possible that M. kozlovi represents just specimens of G. grammicus with a very scattered punctation on the second metasomal tergite.

General distribution: Palaearctic ( China, Iran [new record]) ( Yu et al. 2016).

Diagnosis (Female). Body length 9.5 mm, fore wing length 8 mm, ovipositor 5.6 mm. Malar space 1.7 × as long as basal width of the mandible. Frons weakly convex and weakly striate ( Fig. 4A ). Head behind the eyes not long (0.3 × as long as eyes), curved and weakly narrowed laterally, in dorsal view ( Fig. 4B ). Temple constricted behind the eye, 0.5 × as width as the eye in lateral view ( Fig. 4C ). Notaulus weak ( Fig. 4D ). Mesoscutum polished, strongly punctate. Propodeum ( Fig. 4E ) with basal and apical transverse carinae entire. Apical transverse carinae of propodeum present. First metasomal segment ( Fig. 4F ) rather strongly widened to its apex, without a lateral triangular tooth basally. Postpetiole strongly convex in lateral view. Second tergite somewhat scattered punctate. Fore wing ( Fig. 4G ) vein r-m present. Areolet small and irregular. Vein 1m-cu 2.0 × as long as 1/Cu. Hind wing ( Fig. 4H ) with 1/Cu longer than cu-a. Ovipositor 1.7 × as long as hind tibia ( Fig. 4I ). Body black; frontal and facial orbits, tegula and mesoscutum laterally apically yellowish, all femora, fore and mid tibiae completely, hind tibia mainly and metasoma reddish. Antenna with white stripe on sixth to ninth flagellomeres.
