Two new species of the genus Japananus Ball, 1931 (Hemiptera: Cicadellidae: Deltocephalinae)

摘要

Two new species of the genus Japananus Ball from China are described and illustrated: J. meilingensis sp. nov. and J. lamellosus sp. nov.. A key is given to distinguish all species of the genus. The type specimens of the new species are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC). The leafhopper genus Japananus Ball, 1931 belongs to the tribe Scaphytopiini of subfamily Deltocephalinae with Platymetopius hyalinus Osborn, 1900 as its type species. Until now, fourspecies were known (Osborn, 1900; Matsumura, 1914; Ball, 1931; Oman 1931; Bonfils, 1981; Lauterer, 1984; Viraktamath & Anantha Murthy, 1999; Xing, Dai & Li, 2008). Oman (1931) placed Platymetopius cinctus Matsumura as a junior synonym of Platymetopius hyalinus and Ball proposed the new combination Japananus aceri (Matsumura); Lauterer(1984) placed Japananus meridionalis Bonfils as a junior synonym of Japananus hyalinus. Later, Viraktamath et al (1999) described a new species Japananus nepalicus from Nepal. And Xing et al (2008) described a new species Japananus bicurvatus from China.
