Chilothrips hangzhouensis sp. nov. is described and illustrated in detail. This new species is similar to C. strobilus but can be distinguished from the latter by the two pairs of ocellar setae and the absent of the pore plates on abdominal sternites Ⅲ –Ⅳ（C. strobilus has three pairs of ocellar setae and abdominal sternites Ⅲ –Ⅳ have pore plates）.
Ctenothrips dissimilis sp. nov. is described and illustrated in detail. This new species can be readily distinguished by its 7-segmented antennae and inconspicuous reticulations on the abdominal segments. The male of this species is very similar to C. niger which has short rounded pore plates on sternites III and IV, but can be distinguished from the latter by the elongate elliptical pore plates. The number and the color pattern of antennal segments are also different. Type specimens are deposited in the Entomological Museum of Northwest AF University（NWAFU）.
