A new genus and three new species of the subfamily Phygadeuontinae (Hymenoptera: Ichneumonidae) from northern Vietnam
Abstract
A new Darwin wasp genus, Longipectus gen. nov., is described from northern Vietnam to include three new species Longipectus hagiangensis gen. et sp. nov., Longipectus planus gen. et sp. nov., and Longipectus yagi gen. et sp. nov. Morphologically, the new genus Longipectus differs from other phygadeuontine genera by the combination of the globular head, the long mesosoma, the long notauli, the short first tergite, and the longitudinal wrinkles on the first and second tergites.
