Abstract

Torymus itoi Matsuo sp. nov. (Hymenoptera: Torymidae) is described as a parasitoid of Paratephritis fukaii Shiraki (Diptera: Tephritidae) which induces galls on the petioles and peduncles of Farfugium japonicum (L.) Kitam. (Asteraceae) in Japan. Torymid specimens that were previously identified as T. sapporoensis Ashmead in Ito (1947) are identical with T. itoi, which is shown to be different from T. sapporoensis. To complement the insufficient original description, T. sapporoensis is redescribed based on the holotype.
