The species of six genera (Atanycolus Foerster, Craspedolcus Enderlein, Ectemnoplax Enderlein, Shelfordia Cameron, Stenobracon Szépligeti and Vipio Latreille) of the subfamily Braconinae (Hymenoptera, Braconidae) from China are revised and 29 species are recognized, including 11 new species (Atanycolus carinatus sp. nov., A. longiquus sp. nov., A. maculipennis sp. nov., A. setosus sp. nov., Craspedolcus maculithorax sp. nov., C. nigrabdominalis sp. nov., Ectemnoplax bimaculosus sp. nov., Shelfordia fulva sp. nov., S. obscuripennis sp. nov., Stenobracon (Stenobracon) longatus sp. nov. and Vipio abnormis sp. nov.), which are described and illustrated. Ectemnoplax xizanginensis Wang, Chen et He, 2006, is proposed as a syn. nov. of E. peruliventris Enderlein, 1920. Two species, Shelfordia longicaudata van Achterberg, 1993, and Vipio mongolicus Telenga, 1936, are reported from China for the first time. Keys to the Chinese species of the genera Atanycolus, Craspedolcus, Ectemnoplax, Shelfordia, Stenobracon and Vipio are provided.

Scaevola taccada (Goodeniaceae) is an important evergreen coastal plant on islands in the South China Sea, which shows excellent tolerance for salty and drought conditions. Nevertheless, the growth of S. taccada populations on these islands in the South China Sea has been threatened by a few serious insect pests. However, we know little about the biology of these pests. In this study, we surveyed and identified the parasitoids of two main pests (Herpetogramma submarginale (Swinhoe, 1901) and Ophiomyia scaevolana Shiao and Wu, 1996) of S. taccada communities on Yongxing Island in the South China Sea, with the aim to assess their potential in biological control. Dolichogenidea stantoni (Ashmead, 1904) is a gregarious endoparasitoid of the larva of H. submarginale and contributes an average 48.9% parasitism rate on H. submarginale. Opius biroi, Fischer, 1960 and Euderus albitarsis (Zetterstedt, 1838) are both solitary endoparasitoids of the larva of O. scaevolana, with a respective 5.8% and 64.4% parasitism rate on O. scaevolana. We summarize the species diagnosis, biology, and distribution of the three parasitoid species. The potential of these parasitoids used in biological control is also discussed.

The species of the genus Campyloneurus Szépligeti and Iphiaulax Foerster (Hymenoptera, Braconidae, Braconinae) from China are revised and 32 species are recognized, including 14 new species (Campyloneurus brachyurus sp. nov., C. lasiofacialis sp. nov., C. longitergum sp. nov., C. longitudinalis sp. nov., C. micromacularis sp. nov., C. nigriventris sp. nov., C. promiscuus sp. nov., C. pachypus sp. nov., C. quadraticeps sp. nov., C. robusticella sp. nov., C. rugifacialis sp. nov., C. stigmosus sp. nov., C. tergipunctatus sp. nov. and Iphiaulax longinervis sp. nov.), which are described and fully illustrated. Campyloneurus kirbyi (Cameron, 1905) is reported from China for the first time. A key to taxonomically similar genera, Campyloneurus, Craspedolcus Enderlein, Cyanopterus Haliday, Iphiaulax and Maculibracon Li, van Achterberg & Chen), and a key to the Chinese species of the genera Campyloneurus and Iphiaulax are provided.

Hemiglyptinus Shenefelt, 1978 is a monotypic genus of the subfamily Braconinae (Hymenoptera, Braconidae) with only one described species worldwide. The biology of this genus is still unknown. Up to present, Hemiglyptinus has not been recorded from China. This study reports the first record of the genus Hemiglyptinus in the Hainan Province of China; the newly-recorded species, Hemiglyptinus flavus (Ashmead, 1905), is re-described and illustrated.
