Two new species and a new record of the Encarsia longifasciata-group (Hymenoptera, Aphelinidae) from Malaysia and China

Abstract

The genus Encarsia Förster, 1878, which is the largest genus of the family Aphelinidae, contains 453 valid species worldwide. Most species of Encarsia with known biology are primary endoparasitoids of Aleyrodidae and Diaspididae. Species of the Encarsia longifasciata-group from Malaysia and China are reviewed. This is the first record of this group from Malaysia. Two new species, E. borneensis Geng & Li sp. n. and E. pauroseta Geng & Li sp. n., are described and illustrated. Encarsia longifasciata is newly recorded from Malaysia (Borneo). An updated key to the longifasciata-group species (females) worldwide is provided.
