Descriptions of two new endoparasitic cecidomyiids (Diptera: Cecidomyiidae) from Japan.

Abstract

Two endoparasitic species of Cecidomyiidae (Diptera) new to science are reported from Japan. Females of Endaphis psyllophaga sp. nov. lay their eggs on the wing of Calophya nigridorsalis (Hemiptera: Psylloidea: Calophyidae) on Rhus succedanea (Anacardiaceae), and newly hatched larvae bore into the adult body. The six nominal species of the genus Endaphis are endoparasitoids of aphids. The genus Endopsylla, which is morphologically similar to the genus Endaphis, consists of two species whose larvae attack psyllids or tingids. Females of Endaphis muraii sp. nov. lay their eggs near colonies of host aphids and newly hatched larvae bore into the body of aphids such as Macrosiphum euphorbiae and Aphis glycines (Hemiptera: Aphididae). The two new species are described, illustrated, and compared to known congeners, and information is given for the two species on their distribution, host range and ecological traits. Now, E. muraii is considered to be a potential biological control agent against aphids.
