Abstract

The Asian genus Acerataspis Uchida, 1934 is reviewed based on both morphology and DNA barcodes. Ten species are recognized in total, of which three species from Yunnan Province of China are described as new: Acerataspis maliae sp. nov., A. seperata sp. nov. and A. similis sp. nov. The male of A. fukienensis Chao, 1957 is described and illustrated for the first time. The genus is recorded from Thailand and Southeast Asia for the first time. An illustrated key to all known extant species is provided. With the supplement of DNA barcodes, a few diagnostic morphological characters are found useful in species identification.

Keywords: DNA barcodes; Darwin wasps; Ichneumonoidea; new species; parasitoid.
