Abstract

The delphacid genus Stenocranus Fieber occurring in Japan is morphologically revised, and 10 species including a new species are recognized as follows: S. niisimai Matsumura, S. tamagawanus Matsumura, S. sapporensis Matsumura, S. harimensis Matsumura, S. tateyamanus Matsumura, S. takasagonis Matsumura, S. fallax Matsumura, S. chenzhouensis Ding, S. tonghuaensis Ding, and S. kisimotoi sp. nov. The following synonymies are proposed: S. niisimai Matsumura (=S. matsumurai Metcalf syn. nov. and S. macromaculatus Ding syn. nov.); S. tamagawanus Matsumura (=S. hokkaidoensis Metcalf syn. nov. and S. koreanus Matsumura syn. nov.); S. sapporensis Matsumura (=S. ozenumensis Ishihara syn. nov.); S. harimensis Matsumura (=S. elongatus Matsumura syn. nov.); S. takasagonis Matsumura (=S. rufilinearis Kuoh syn. nov.); S. tateyamanus Matsumura (=S. sukumonus Matsumura syn. nov.). Two species are transferred from Stenocranus to a new genus, Ceratocranus gen. nov.: C. agamopsyche (Kirkaldy) comb. nov. and C. linnapallidus (Asche) comb. nov. A new species, C. aurantius sp. nov., is also described from Japan. In addition, Stenocranus formosanus Matsumura syn. nov. is regarded as a junior synonym of C. agamopsyche. Furthermore, the Japanese species of Stenocranus are morphologically classified into four species groups, and their phylogenetic relationships are discussed.
