Taxonomic review of the mirine plant bug genus Stenotus Jakovlev in Japan and adjacent regions in Asia (Hemiptera: Heteroptera: Miridae: Mirinae)

Abstract

The mirine plant bug fauna of the genus Stenotus Jakovlev in Japan, Korea, East China, and Russian Far East is reviewed. Seven species are recognized in the study area; of these, two new species are herein described, namely S. hasegawai sp.n., restricted to cool-temperate climate zones in Japan and Sakhalin, Russia and S. takaii sp.n. assumed to be endemic to Amami-Oshima Island of the Japanese Ryukyus. The Taiwanese species, S. insularis Poppius, is reported from the Ryukyus for the first time and redescribed; the other taxon, S. viridis (Shiraki), is regarded as a nomen dubium, lacking any type series. An additional new species from Nepal, S. ramduwalae sp.n., is described. A checklist of East Asia and Oriental species and a key to all known East Asian species are provided. Stenotus longiceps Poppius is transferred to Zalmunna Distant. The zoogeography of these East Asian Stenotus species is discussed.
