Mesopolobus incultus auct. (Hymenoptera : Pteromalidae) contains two distinct species: Mesopolobus incultus (Walker, 1834) and Mesopolobus amyntor (Walker, 1845)
Mesopolobus incultus auct. is hypothesized to consist of two different species, M. amyntor (Walker) and M incultus (Walker). This hypothesis is supported by molecular (cytochrome c oxidase subunit I, i.e. COI), morphological and biological data. Mesopolobus amyntor is a primary parasitoid of Mecinus pascuorum (Gyllenhal) and M. labilis (Herbst) (Coleoptera: Curculionidae) on Plantago lanceolata. M
