Six new genera of the family Braconidae (Hymenoptera) from China are described and illustrated: two genera of the subfamily Agathidinae: Facilagathisgen. nov. (type species: F. spinulataspec. nov.) and Cremnoptoidesgen. nov. (type species: Cremnops pappiSharkey, 1994); one genus of the subfamily Hel- coninae: Mangshiagen. nov. (type species: M. elongataspec. nov.); two genera of the subfamily Pam- bolinae: Plesiocedria gen. nov. (type species: P. intermediata spec. nov.) and Apocedria gen. nov. (type species: A. nodiferspec. nov.) and one genus belonging to the subfamily Opiinae: Opiolastesgen. nov. (type species: O. heispec. nov.). In addition two new species are described: Facilagathis macrocentroides spec. nov. from Zhejiang and Cremnoptoides furcatusspec. nov. from Jilin. Introduction The knowledge of the members of the family Braconidae Nees, 1812 (Hymenoptera) in China is still limited (He et al., 2000). We are just starting to understand the diversi- ty of the family in this area. During some recent visits of the first author to the Zhe- jiang University at Hangzhou several new genera were found in the collection of the Institute of Applied Entomology, of which six are described in this paper. The biology of the new genera is unknown, but members of the subfamily Agathidinae Haliday, 1833, are koinobiont endoparasitoids of larvae of Lepidoptera. Members of the sub- family Helconinae Foerster, 1862, are koinobiont endoparasitoids of larvae of Coleoptera; of the subfamily Pambolinae Marshall, 1885, are idiobiont ectoparasitoids of larvae of Coleoptera and Lepidoptera and of the subfamily Opiinae Blanchard, 1845, are koinobiont endoparasitoids of larvae of cyclorraphous Diptera. For the identification of the subfamilies, see van Achterberg (1990, 1993, 1995, 1997) and for the terminology used in this paper, see van Achterberg (1988, 1993).

Six new Braconidae genera from China.Zool. Med. Leiden 78 (2004) Descriptions Agathidinae Haliday, 1833 Facilagathis gen. nov. (figs 1-18) Type species: Facilagathis spinulataspec. nov. Etymology.— From “facilis” (Latin for “easy”) and the generic name AgathisLa- treille, 1805, because it belongs to the Agathis-group, but is easily separable by the spiny pegs of the hind basitarsus, the very slender first metasomal tergite and the reduction of vein 2-CU of the hind wing. Gender: feminine. Diagnosis.— Length of fore wing 4.7-5.2 mm; head distinctly narrowed but not elongate ventrally, its malar space distinctly longer than basal width of mandible (figs 6, 14, 16); antenna somewhat shorter than body, with 38-40 segments, its apex acute and without apical spine (fig. 8); labio-maxillary complex not enlarged (fig. 14); area between antennal sockets without a pair of crests (fig. 6); area behind antennal sockets slightly depressed (fig. 7); frons without lateral carinae (fig. 7); temple in lateral view straight medio-posteriorly (fig. 14); mandible extremely twist- ed and plate-like in anterior view (fig. 6); prepectal carina lamelliform ventrally and incised medially; precoxal sulcus present (except anteriorly) and (largely) crenulate or costate (fig. 14); notauli complete (fig. 4); scutellum without crest-like elevation subposteriorly and with distinct depression medio-posteriorly (fig. 4); propodeal spiracle medium-sized and round (fig. 14); propodeum mainly rugose-reticulate, areola and costulae absent (fig. 4); vein 2-R1 of fore wing longer than vein 1-R1 or subequal (fig. 1); vein M+CU of hind wing shorter than vein 1-M (fig. 1); vein 2-CU of hind wing absent or nearly so; hind wing with 3 hamuli; hind coxa elongate, nearly as long as hind femur (figs 2, 17); all tarsal claws simple, and with acute lobe (fig. 8); fore tibial spur about 0.4 times fore basitarsus, without long glabrous apical spine; length of inner middle spur about 0.3 times middle basitarsus; outer face of middle tibia without submedial pegs; hind trochantellus with its lower edges rounded, without ventral carina; hind basitarsus with numerous spiny pegs latero- ventrally (figs 2, 3, 17, 18); first metasomal tergite very slender (5-6 times longer than wide apically) and largely longitudinally striate, without lateral depressions (figs 5, 15) and laterope large (fig. 14); second tergite striate and third tergite smooth; second metasomal suture wide, rather shallow and more or less striate (figs 5, 15); ovipositor narrow, without teeth and straight (fig. 13); ovipositor sheath 1.5- 1.8 times as long as fore wing, subparallel-sided, apically with short spine and ven- trally, and much longer than apical height of metasoma (figs 13, 14). Distribution.— North Oriental; two species. Biology.— Unknown. Notes.— The genus is superficially similar to a very slender member of the genus Bassus Fabricius, 1804, but can be separated by the numerous spiny pegs of the hind basitarsus ventrally, the very slender first metasomal tergite and hind coxa, and the absence of a distinct trace of vein 2-CU of the hind wing. van Achterberg & Chen.
