An investigation of the species and distribution of parasitic wasps of Parasaissetia nigra Nietner attacking rubber trees was made in the rubber plantations and rubber holdings in the state farms, small or collective holders, and Yunnan Institute of Tropical Crops in Xishuangbanna, Yunnan Province from 2007 to 2009. Collected and identified were 2 458 individuals of parasitic wasps of P. nigra Nietner which are grouped into 12 species of 11 genera and 4 families. Diversinervus elegans and Tetrastichus murakamii were found to be the dominant species parasitizing P. nigra Nietner; Microterys rufofulvus, Coccophagus ceroplastae, Anysis saissetiae, Coccobius sp. and Marietta sp. were common species. The morphological characters of the dominant and common species are illustrated, and a key to the species of parasitic wasps of P. nigra Nietner in Xishuangbannna is provided.
