New Records of the Genus Picrostigeus (Hymenoptera: Ichneumonidae: Orthocentrinae) from the Eastern Palaearctic

Two orthocentrine species, Picrostigeus karafutus sp. n. and P. debilis (Gravenhorst, 1829) from Sakhalin, are recorded for the first time from the Eastern Palaearctic. Picrostigeus karafutus sp. n. is similar to P. brevicauda Horstmann, 1994 in having a short ovipositor, but differs by the longer first flagellomere, more strongly narrowed temples, and vein 3rs-m in the fore wing present.

Abstract

Two orthocentrine species, Picrostigeus karafutus sp. n. and P. debilis (Gravenhorst, 1829) from Sakhalin, are recorded for the first time from the Eastern Palaearctic. Picrostigeus karafutus sp. n. is similar to P. brevicauda Horstmann, 1994 in having a short ovipositor, but differs by the longer first flagellomere, more strongly narrowed temples, and vein 3rs-m in the fore wing present.
