Parasitoidism of Dermaptera by Braconidae (Hymenoptera) confirmed

<i>Orionis coxator</i> (Belokobylskij, 1995) (Hymenoptera: Braconidae: Euphorinae: Perilitini) was reared from an individual of <i>Apterygida tuberculosa</i> Shiraki, 1928 (Dermaptera: Forficulidae) in Taiwan. This represents a new record of <i>O. coxator</i> and the genus <i>Orionis</i> 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 <i>O. coxator</i> 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 <i>A. tuberculosa</i> and other species of Dermaptera in Taiwan are discussed.
