Verheyde, Fons, Hoekstra, Paul, Libert, Pierre-Nicolas, Meijer, Hilco, Ketelaere, Augustijn De, Vandaudenard, Thibaud, Belgers, Dick & Brosens, Edwin, 1880, Two hundred and five ichneumonid wasps reported for the first time in Belgium and the Netherlands (Hymenoptera: Ichneumonidae), Belgian Journal of Entomology 122, pp. 1-142 : 28-29

Erigorgus procerus (Gravenhorst, 1829) (Fig. 5)

E. procerus is easier to recognise than E. melanops . The tarsi are yellowish (without any ivory patterns). The females only have red coxae, but males sometimes tend to have black hind coxae basally (Fig. 5). Lastly their antennae are largely orange/reddish, turning darker apically ( PÉNIGOT 2021, in press). This species does not seem to be rare. Some host records need to be further confirmed, but certainly used as a host is Polia nebulosa (Hufnagel, 1766) ( Lepidoptera : Noctuidae ) ( RUDOW, 1917; pers. comm. W. Pénigot).

First report for Belgium and the Netherlands.
