Iania pictifrons (Thomson, 1877)

= syn. Dreisbachia pictifrons (Thomson, 1877) , synonymized by MATSUMOTO (2016: 8–9)

A small genus in Western Europe. It belongs to the pimpline group with a closed areolet in the fore wing. The presence of 3rs-m in the fore wing veins immediately distinguishes it from other polysphinctine wasps. The fore tarsal claw has a tooth-like basal lobe and the occipital carina is evenly convex mediodorsally. The ovipositor is tapered from the middle to the apex in lateral view (FITTON et al., 1988).

Iania pictifrons otherwise superficially resembles other polysphinctines, as mentioned above, for example Zatypota percontatoria (Müller, 1776) , which also has reddish zones on its mesopleuron and its metapleuron in combination with yellowish to white trochanters. The species has been questionably synonymised with Schizopyga by GAULD & DUBOIS (2006) and was finally transferred to the new genus Iania ( MATSUMOTO, 2016) .
