A new host record for the cleptoparasite Irenangelus lucidus (Evans, 1969) (Hymenoptera: Pompilidae)
Entomological Communications, 2021 We provide a new host record for the cleptoparasitic wasp Irenangelus lucidus (Evans, 1969) (Pompilidae: Ceropalinae). A single female emerged from a brood cell of the host species Auplopus militaris (Lynch-Arribalzaga, 1873) (Pompilidae: Pepsinae ...
