Abstract
Five species of the genus Testudobracon Quicke, 1986 in Vietnam were recognized, and four new species, viz. Testudobracon alius Long, sp. nov., Testudobracon descensus Long, sp. nov., Testudobracon imitator Long, sp. nov., and Testudobracon phiaoacus Long & PQMai, sp. nov. are described and fully illustrated. Additionally, the genus Testudobracon and one species, Testudobracon flavus Tang, Chen & He, 1997, are newly recorded for the Vietnam’s braconid fauna. A checklist of the already known of Testudobracon species is provided, a key to Vietnamese species of the genus Testudobracon in Vietnam, their in-country distribution, and differentiation of the known similar species are also given.
