Perilissus albitarsis Thomson, 1883 View in CoL (Fig. 32 A–B)
Perilissus spp. can be recognised by its habitus with some experience. The genus comprises both testaceous species which are often caught with light traps, and species caught in springtime and summer near its hosts ( Dolerus spp. ) on grasses. The species are rather robust with a specific wing venation, namely a subvertical to strongly reclivous nervellus in the hind wing (more details see TOWNES, 1970b). The genus is currently under revision by Gavin Broad and the wasps reported here were confirmed by him. For identification purposes, we used a draft key (edition 2017) which was made available to us.
P. albitarsis has a completely testaceous body, including the pterostigma (Fig. 32 A). Furthermore, its mesopleuron and its mesoscutum are weakly coriaceous, its malar space is short, the ocelli large (Fig. 32 B) and the propodeum has weakly defined carinae. Additionally, the tarsal claws are pectinate ( ZWAKHALS & BLOMMERS, 2020), which is one of the characteristics to distinguish it from P. pallidus (Gravenhorst, 1829) .
First report for Belgium; confirmed in the Netherlands.
