Diglyphus scapus Yefremova

Figs 45–48

Diglyphus scapus Yefremova in Hesami et al., 2008, holotype female in ZISP, examined.

Diagnosis. Female scape white with apical ⅓ dark brown (Fig. 48), male antenna yellowish-white with scape strongly swollen (Fig. 47), 1.5× as long as wide; legs (Fig. 48): fore femur with basal ½ dark brown and apical ½ white, mid femur predominantly dark brown with very apex white, hind femur with basal ¾ dark brown and apical ⅓ white; fore tibia white, mid tibia with basal ½ dark brown and apical ½ white, hind tibia white with a dark brown ring close to base; fore wing speculum bare; submedian grooves on scutellum pale (Figs 45–47).

Material. Iran: female holotype and two male paratypes of D. scapus (ZISP) .

Distribution. Iran (Hesami et al. 2006).

Remarks. The type material of D. scapus is in poor condition (Figs 45–48) and appears morphologically heterogeneous as compared to other species of Diglyphus . The two paratype males differ considerably in the colour of the head. In one specimen the head is dark and metallic (Fig. 46) but in the other male it is completely pale nonmetallic (Fig. 47). The dark-headed male lacks the antennae (probably lost after the description as they are included in the description, or on slide but slide not found), whereas the pale-headed male has both antennae intact, albeit in poor condition. It is possible that the dark-headed male and the holotype female are conspecific, and the paleheaded male is a different species. However, without additional material in better condition, biological and/or molecular data, this is impossible to establish.

Contrary to what is written in the original description of the holotype female of D. scapus the flagellomeres are not yellow, they are pale brown (Fig. 48) and as the specimen appears slightly bleached they may have been dark brown originally.
