Orionis coxator (Belokobylskij, 1995) (Hymenoptera: Braconidae: Euphorinae: Perilitini) was reared from an individual of Apterygida tuberculosa Shiraki, 1928 (Dermaptera: Forficulidae) in Taiwan. This represents a new record of O. coxator and the genus Orionis Shaw, 1987 from Taiwan, as well as the first confirmed case of a hymenopteran species as a primary parasitoid of a dermapteran. The male of O. coxator is redescribed and illustrated, and its diagnostic characters are discussed. Published records of parasitoidism of Ichneumonoidea and other Hymenoptera in Dermaptera and other Polyneoptera are briefly reviewed, and some biological aspects of parasitoidism of braconids in A. tuberculosa and other species of Dermaptera in Taiwan are discussed.
Hsu et al. (Wed,) studied this question.
