【Objective】To investigate the species and distribution of Melanthripidae，Thysanoptera in China.【Method】Collected thrips specimens from various host plants by flapping method，then mounted slides and identified the species.【Result and conclusion】Three species of the genusMelanthripswere found in China，of whichMelanthrips knechteliPriesner was a newly recorded species.Description and illustrations of the new record species，and an identifying key and the diagnostic features of the known species of ChineseMelanthripswere provided.

Melanthripidae is one of the eight families recognized in the suborder Terebrantia.Members of this family feed on flowers，which is also the place for their breeding［1］.The members of this family are identified by having a pair of lobes with an associated two pairs of setae on the posterior margin of the seventh sternite;a well developed pair of trichobothrium on the tergite X; transverse sensoria on the antennal segments，and a fully devleoped tentorium in the head.

This family includes 65 species in four genera，of whichMelanthripswith 36 species is the largest genus［2］.In China，the genusMelanthripswas recorded with two species：M.fuscusandM.pallidior［3］;and there is the third species：M.knechteli，which is recorded for the first time.Specimens for study were mounted with Canada balsam.Illustrations were made using a camera lucida.The specimens are now preserved in the insect museum of department of entomology，South China Agricultural University，Guangzhou(SCAU).
