Contribution to the Knowledge of the Subgenus Prosapha stat. n. of the Genus Dinotrema (Hymenoptera, Braconidae, Alysiinae)

摘要

Prosapha Foerster, 1862 was described originally as a genus. Later, it was synonymized with the genus Dinotrema Foerster, 1862 by Achterberg (1988). Prosapha is resurrected here as a subgenus of Dinotrema. Three species are described from the RussianFar East: Dinotrema (Prosapha) comptum sp. n., D. (P.) pachysemoides sp. n., D. (P.) ussuriense sp. n. A diagnosis of the subgenus Pjrfjapha and a key to its five species are given. D. (P.) pachysemoides differs from D. (P.) speculum (Hal.), the type species of the subgenus Prosapha, in the long radial and the second radiomedial cells in the male. D. (P.) comptum differs from D. (P.) speculum in the mandibles widened to the apex, longer and compressed abdomen, shorter sternauli, longer discoidal cell, and wider pterostigma in the female. D. (P) ussuriense is similar to D. (P). tobiasi from Moldova and differs from it in the mesoscutum without mesoscutal pit, long antennal segments, long abdominal tergite I, and rugose propodeum without transversal carina.
