Monoctonus crepidis (Haliday) (Hymenoptera: Aphidiidae) an Aphid Parasite New to North America
Published online by Cambridge University Press: 31 May 2012
Extract
Examination of the aphid parasites in the Canadian National Collection, Ottawa, provided evidence that several well-known European species are much more widely distributed than has been assumed. Material of the genus Monoctonus Haliday 1833 contained 11 females and 7 males of a species which was identified as Molonoctonus crepidis (Haliday 1834). A comparison with specimens from various European localities did not reveal any differences in the external morphology or in colour. This is the first record of this species from North America.
