A NEW CHINESE RECORD SPECIES TORYMUS BEDEGUARIS (HYMENOPTERA, TORYMIDAE)

A newly recorded species Torymus bedeguaris (L.) is reported in China for the first time. The species was reared from gall of Diplolepis rosae (L.) on Rosa serrata X R. rugosa (Rosaceae: Rosa). Morphological descriptions, hosts and distributions are provided. All the specimens are deposited in the Zoological Museum, Institute of Zoology, Chinese Academy of Sciences and herbarium of Lanzhou Agro-technical Research and Popularization Center. Torymus bedeguaris (Linnaeus), 1758 New record to China (Figs 1-7) Head in front view (Fig. 1) about 1.23 times as high as wide; eye height about 3 times as long as malar space. Head in dorsal view about 2.13 times as long as wide; occipital carina distinct. Base of scutellum (Fig. 2) narrow but not pointed, frenal line absent. Propodeum (Fig. 4) reticulate without median carina. Cubital vein (Fig. 3) with row of setae basally, basal vein and costal cell with conspicuous setal rows. Fore coxae (Fig. 5) essentially green, hind coxae with dorsal setae, hind tibial spur about 1/2 shortest length of basitarsus. Ovipositor 2.11 times length of abdomen. Torymus bedeguaris is similar to T. solitarius and T. chrysochlorus. T. bedeguaris differs from T. chrysochlorus in having the hind coxae with dorsal setae and the intermalar distance 2 times as long as malar space; but T. chrysochlorus without dorsal setae on hind coxae, intermalar distance 2.5 times as long as malar space. T. bedeguaris can be separated from T. solitarius by the green fore coxae, the orange-yellow femora, the stigmal club obviously darker brown than the marginal vein, and the hind tibial spur about 1/2 the length of the basitarsus; but T. solitarius with fore coxae mostly yellow, femora pale yellow, vein concolorous light brown, and the hind tibial spur about 1/3 the length of the basitarsus (Grissell, 1976).
