Th e few keys available for the Oriental Region are outdated (e.g., Bhat and Gupta 1977) or are limited to an island (Chou and Sharkey 1989). Th ose limited to a country (Sharkey 1996, Chen and Yang 2006) deal with a partly or completely East Palaearctic fauna. Only the genus Eu- agathis Szépligeti, 1900, has received more attention (van Achterberg and Chen 2002). Th is paper is an attempt to give an overview of the diversity of Agathidinae of Vietnam Revision of Agathidinae of Vietnam 3 and to supply keys to the taxa. For the fi rst time all available Vietnamese species are illustrated by colour photographs. Th e study of variation in most species is severely hampered by the lack of specimens, so the keys presented here are just a start to a better understanding of the diversity of the subfamily in Vietnam. Th e paper by Sharkey et al. (2009) on the Oriental genera of Agathidinae (with special attention to the fauna of Th ailand) appeared just before the present paper was fi nished and deals with a similar fauna. It is an important attempt to summarize the latest results on the phylogeny of the subfamily and deals with some recent fi nds in Th ailand. However, the number of genera found in Vietnam is higher than in Th ailand; e.g. the genus Bassus Fabricius s.s. is not recorded for Th ailand, and we found two new genera in Vietnam. Th e diff erent interpretation of some diagnostic characters, the use of additional characters, the cor- rect interpretation of a type species and the new genera are suffi cient reason to include a new key to the genera in our review. We propose another generic name (Zelodia van Achterberg gen. n.) for one genus following the correct interpretation of a type species. In addition, keys to all known species from Vietnam are presented and the 42 species new to science are described and illustrated. Th e new species represent two-thirds of the total number of species of Agathidinae known from Vietnam. Th e biology of most species is unknown, but in general agathidines are koinobiont endoparasitoids of larvae of Lepidoptera. Th e species with a short ovipositor select exposed larvae and those with a long ovipositor use larvae with a concealed way of life. Material and methods Two recent (and probably largest) collections of agathidines from Vietnam are used for this revision: the Braconidae collection in the Institute of Ecology & Biological Resources (IEBR) at Hanoi (assembled by the second author) and the NCB Naturalis collection (RMNH) at Leiden (assembled during fi ve RMNH-IEBR expeditions in Vietnam).
