Abstract

Morphological studies of different populations of what was previously considered to be a single species, Aphanogmus hakonensis Ashmead, revealed the presence of a complex of species which are extremely difficult to distinguish without detailed studies of male genitalia. Several of these species have been misidentified during biological control programmes or parasitoid surveys. These misidentifications are corrected, and two new species, Aphanogmus captiosus and Aphanogmus thylax are described. The hakonensis-complex is diagnosed. As far as is known, all species are hyperparasitoids of lepidopteran larvae via various hymenopteran or dipteran primary parasitoids.
