摘　　要：记述了采自四川泸定的齿扁蜂属Onycholyda Takeuchi 2新种:泸定齿扁蜂 Onycholyda ludingica, sp. nov. 和刻纹齿扁蜂Ohycholyda microsculpturalis, sp. nov., 其中刻纹齿扁蜂右上颚具4齿,在该属中还是第一次报道。模式标本保存于中南林学院昆虫标本室。Two new species of Onycholyda Takeuchi are described and illustrated from Luding, Sichuan Province, China. Type specimens are deposited in the Insect Collections of Central South Forestry University, Zhuzhou, China. 1. Onycholyda ludingica, sp. nov. (Figs.1~4) Female: Body length 11.5 mm. This species is similar to O. kumamotonis, but differs from the latter by: a big teeth-like yellow mark on upper frons, malar space yellow with a black stripe medially; antenna wholly yellow, stigma brownish with basal 1/8 pale; right mandible tridentate with incision between apical and median teeth much deeper than that between median and basal teeth. In O. kumamotonis, there are two irregular yellow spots on upper frons, malar space wholly black, antenna blackish brown to black, stigma blackish brown with basal 1/2 and anterior margin yellowish; right mandible tridentate with incision between apical and median teeth much shallower than that between median and basal teeth. Male: unknown. Holotype: ♀, Hailuogou, 2 200~2 600 m, Luding County, Sichuan Province, 17-Ⅶ-2003, coll. XIAO Wei. 2. Onycholyda microsculpturalis, sp. nov. (Figs.5~8) Female: Body length 10.5 mm. This species is close to O. lucida (Rohwer), but it is different from the latter by: antenna yellow, most of each trochanter and femora wholly yellow; dense sculptures present on places of clypeus medially, upper orbit, vertex and thorax; right mandible with four teeth. In O. lucida, antenna with scape and pedicel black and flagellum blackish brown to black; each trochanter and basal 1/2 of femora black; head smooth with very sparse and small punctures, anterior part of vertex feebly coriaceous, gena and narrow anterior margin of clypeus more densely puncturated, thorax smooth; right mandible tridentate. Usually in Onycholyda, the left and right mandibles are bidentate or tridentate, but in O. microsculpturalis, the right mandible with four teeth. Male: unknown. Holotype: ♀, Hailuogou, 3 000~3 100 m, Luding County, Sichuan Province, 18-Ⅶ-2003; coll. LIU Wei-x
