Pseudorhyssa alpestris (Holmgren, 1860) View in CoL
Pseudorhyssa View in CoL is a very distinctive genus consisting of giant species with conspicuous transverse rugae on their mesoscutum (and thus closely resembling Rhyssinae ). In contrast to this subfamily the occipital carina is complete medio-dorsally and the fore wing vein 1cu-a is situated opposite of M&RS (BROAD et al., 2018). Both species reported here are migratory and only recently colonized the Low Countries, coming from central and eastern Europe (see also VERHEYDE et al., 2020a). The genus was recently transferred from the subfamily Poemeniinae to Pimplinae ( KLOPFSTEIN et al., 2018) .
P. alpestris View in CoL has red hind coxae and the first two tergites usually have a smooth reddish triangle apically ( VARGA, 2015). It is mainly associated with and found on hardwood, where it acts as cleptoparasitoid of for example Rhyssella approximator (Fabricius, 1793) View in CoL , an ichneumonid wasp which belongs to the abovementioned subfamily of Rhyssinae (HILSZCZANSKI, 2018) .
