Schizopyga circulator (Panzer, 1800)

Schizopyga spp. are smaller pimpline spider parasitoids with the fore wing vein 3rs-m entirely absent. Their clypeus and face are confluent, forming a nearly flat surface (FITTON et al., 1988).

The females of S. circulator are easy to recognise: it is the only species with the metasoma (at least tergites 4 and 5) completely red. The males are trickier. Their face is black, the mid femur red but blackish at apex, the tegulae are mostly brown or black and the metapleuron is rather closely punctate (sculpture contrasting with shiny adjacent area of mesopleuron). Its antenna has about 23–25 segments ( SHAW, 2006). Common and widely underreported in both countries.

First report for Belgium; confirmed in the Netherlands.
