First record of the genus Testudobracon Quicke, 1986 (Hymenoptera: Braconidae: Braconinae) in Vietnam, with description of four new species.

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.

The identity of Chivinia Shestakov (Hymenoptera: Braconidae, Braconinae), with description of a similar species from the Oriental region.

A peculiar new species from Vietnam (Bracon (Pseudochivinia) tobiasi Long & van Achterberg, sp. nov.) is described and illustrated. It is included in a new subgenus Pseudochivinia Long & van Achterberg, subgen. nov., because it does not fit into the superficially similar subgenus Chivinia Shestakov. The new subgenus shares with Chivinia Shestakov the absence of vein r-m of the fore wing (resulting in the absence of a closed second submarginal cell) but can be distinguished from Chivinia and other subgenera of the genus Bracon Fabricius by the deep and crenulate medio-longitudinal depression of the first metasomal tergite and the different venation. Bracon (Chivinia) zimini Shestakov, 1932 is redescribed and illustrated for the first time.

Four new species of the subfamily Braconinae (Hymenoptera: Braconidae) from Vietnam.

This paper contains descriptions and illustrations of four new species of braconine wasps from two genera Megalommum Szpligeti, 1900 and Nedinoschiza Cameron, 1911 from Vietnam, viz. Megalommum hoabinhense Long, sp. nov., M. simulatum Long, sp. nov., M. sonlaense Long, sp. nov. and Nedinoschiza khuathalinhae Long, sp. nov. Additionally, the genus Megalommum is the first record for Vietnam.

First record of the genus Trispinaria Quicke, 1986 (Hymenoptera, Braconidae, Braconinae) in Vietnam, with descriptions of two new species.

Two new species of the genus Trispinaria Quicke, 1986, from Vietnam, viz. T. seminigra Long, sp. nov. and T. vietnamica Long, sp. nov., are described and fully illustrated. Additionally, this is the first record of the genus Trispinaria in Vietnam. A checklist with distributions of previously described species of the genus Trispinaria is given. Comparative characters of the Vietnamese species are provided and modified key couplets are provided to facilitate their identification.

A new species of Zaglyptogastra Ashmead, 1900 (Hymenoptera: Braconidae: Braconinae) from Vietnam.

The moderately large genus Zaglyptogastra Ashmead, 1900 is newly recorded for Vietnam and one new species, Z. vietnamica Long sp. n., is described and illustrated. Differences between the new species and two described species, Z. aswada El-Heneidy & Quicke, 2007, from Indonesia (Sumatra) and Z. vitalisi (Turner, 1919), from Laos, are given.
