Chelonus (Chelonus) olgae Kokujev, 1895 ( Figures 3A–3F )

Material examined: Hamadan Province: Asadabad, Galehbor (34°50′N, 48°10′E, 2150 m a.s.l.), 25.07. 2016, 2♀♀ ( ICRIFR); leg.: A. Rajabi Mazhar .

Diagnostic characters (Female): Length of body 6.6 mm; antennae 45-segmented, as long as length of body, length of the 1st flagellar segment 4.0 times its width, apical segments of antenna twice as long as their width; temple shorter than eye in dorsal view, slightly smoothed sculpture ( Figure 3A ); width of face twice its height, transversely striate and punctate ( Figure 3B ); mesoscutum punctate, weakly in anterior part and coarsely in posterior part ( Figure 3C ); anterior margin of marginal cell of forewing slightly shorter than pterostigma ( Figure 3D ); metasomal carapace distinctly narrowed apically ( Figure 3E ); length of metasomal carapace 2.5 times its maximum width in anterior third, densely and rather coarsely punctate, with longitudinal rugae in basal half ( Figure 3E ); apical sternites slightly projecting from under carapace ( Figure 3F ).

Coloration: Body black ( Figure 3F ); mesosoma reddish (except propodeum), scutellum dark brownish; metasoma black with two indistinct brownish; maxillary palps and mandibles brownish; wings infuscate, basal half with pale yellowish veins; hind leg black, hind tibia black, with a median pale band.

Distribution: Georgia, Germany, Hungary, Kazakhstan, Spain, Turkey, Uzbekistan ( Yu et al., 2016), Iran (new record).

Remark: According to the redescription by Tobias (2011) the metasoma should be brownish with pair of yellow basal spots, but the metasoma of the Iranian specimens is black, with indistinct brownish basal spots. We consider the Iranian specimens to be a melanistic form of C. olgae .
