Review of the Palaearctic Trathala Species (Hymenoptera: Ichneumonidae: Cremastinae)

The Palaearctic species of the genus Trathala Cameron are reviewed. Genus Trathala is the third largest group. This genus was described Trathala striata by Cameron for the first time in the world. One hundred one species of this genus have been recorded worldwide. Trathala flavoorbitalis Cameron and Trathala hierochontica (Schmiedeknecht) were recorded from Palaearctic. Here we report three species, Trathala flavoorbitalis Cameron, Trathala hierochontica (Schmiedeknecht) and Trathala striata Cameron, from Palaearctic region. Among them, Trathala striata Cameron is a newly recorded species for the first time from Palaearctic region and South Korea. Redescriptions of Palaearctic Tranthala species with photographs and a key to the Palaearctic Trathala species are provided.
