Abstract

The Oriental genus of Eurybrachidae (Hemiptera, Fulgoromorpha) Purusha Distant, 1906 is reviewed and a key to the genera of Eurybrachini is given. Two new species, P. bellissima sp. nov. and P. vietnamica sp. nov. are described from Myanmar and North Vietnam, respectively. Purusha rubromaculata Distant, 1906 is proposed as a junior synonym of P. reversa (Hope, 1843). All species are illustrated, including all type specimens and the male genitalia for the first time. Distribution maps, identification key to species and biological data are provided. The sexual dimorphism in the genus is discussed. Five species are currently placed in Purusha.

Keywords: Eurybrachinae; planthopper; Fulgoroidea; Auchenorrhyncha; sexual dimorphism
