Abstract(cid:1) The genusFurcadesha Quicke of the tribe Adeshini van Achterberg(Hymenoptera, Braconidae, Braconinae) isrecorded
fromChina for thefirst time. Twonew species, Furcadesha nanningensis Liu et Chen, sp. nov. and Furcadesha bimaculatus Yang et
Liu, sp. nov. are described. Akey to species ofthe genus isprovided. The type specimensare deposited in the Benificial Insects
Laboratory, College of Plant Protection, Fujian AgricultureandForestry University, China.
