Pamphilius tibetanus (Hymenoptera, Pamphiliidae) and its Close Relatives

摘要

Pamphilius tibetanus group is defined to include four species occurring in the southeastern marginal area of the Palearctic region: P. tibetanus Shinohara, Naito & Huang, 1988, from eastern Xizang (Tibet), China, and eastern Nepal, P. himalayanus Shinohara & Singh, 1989, from Himachal Pradesh, northern India, P. foveatus n. sp. from Yunnan, southern China, and P. sinensis n. sp. from Shaanxi, central China, and Yunnan, southern China. Descriptions are given for the two new species and the previously unknown male of P. tibetanus. Pamphilius lanatus Benes 1982, from Gansu, central China, is compared with the members of the tibetanus group. A hypothesis of the relationship of the four component species as well as a key to separate them are given. This is the first record of the family Pamphiliidae from Nepal.
