Two new European species of Cotesia Cameron, 1891 (Hymenoptera: Braconidae, Microgastrinae) parasitizing butterflies (Lepidoptera: Papilionoidea), and an unrelated synonymy in the genus

Abstract

• Two new European species of Cotesia are described and illustrated. One (C. euchloevora Shaw, sp. nov.) was reared from Euchloe species and close relatives and also Aplocera efformata, and the other (C. parnassii Shaw, sp. nov.) was reared from Parnassius phoebus. Notes are given to distinguish them from congeners. The DNA barcodes of C. euchloevora are discussed in relation to similar barcodes for another, but morphologically clearly distinct, species Cotesia pilicornis (Thomson). Unrelated to this, it is proposed that C. acutula (Tobias) is a junior synonym of C. cajae (Bouché).
