Revision of the Genus Deuteroxorides Viereck, 1914 (Hymenoptera, Ichneumonidae, Poemeniinae), from Japan

Abstract

Japanese species of the genus Deuterixorides Viereck, 1914, are reviewed. A new species of this genus, D. breviterebratus sp. nov., is described. This species resembles D. orientalis (Uchida, 1928) in having the black hind coxa and femur, but can easily be distinguished from D. orientalis in different morphological characters such as colouration of coxae and tegula and lendth of oviposition. D. atratus Kasparyan, 1976, is newly synonymized under D. orientalis (syn. nov.). Therefore, only two species of Deuteroxorides are recognized from Japan. A key to world species of this genus is provided.
