The genus Colotrechnus Thomson, 1878 (Hymenoptera: Pteromalidae) in the North- and South-Eastern provinces of Iran

A survey was carried out on the genus Colotrechnus Thomson, 1878 (Hym., Pteromalidae) in North Eastern (North Khorasan) and South Eastern (Kerman) provinces of Iran. Two species including Colotrechnus subcoeruleus Thomson, 1878 and Colotrechnus viridis (Masi, 1921) were found, of which the first species is newly recorded from Iran. The new findings represent distribution of this genus along a wide area in Eastern provinces of Iran. An illustrated key to known Iranian species, as well as a brief diagnosis for each species are provided. A distribution map throughout the Palaearctic region is also generated and discussed.
