review of the genus Pimpla Fabricius, 1804 (Hymenoptera: Ichneumonidae: Pimplinae) from Vietnam with descriptions of two new species

The ichneumonid wasp genus Pimpla Fabricius, 1804 is reviewed for the first time from Vietnam. Two new species are described: Pimpla lexuanhuei sp. nov. from Phu Tho Province and Pimpla chuyansinensis sp. nov. from Dak Lak Province. Five further species are recorded as new for Vietnam: P. bilineata (Cameron), P. cameronii Dalla Torre, P. ereba Cameron, P. flavipalpis Cameron, and P. laothoe Cameron. Pimpla instigator (Fabricius, 1793), a junior synonym of P. rufipes (Miller, 1759), previously recorded from Vietnam, was re-identified as P. laothoe and therefore is excluded from the ichneumonid fauna of Vietnam. A key to all ten species listed in this paper is also compiled.
