The plant bug tribe orthotylini in Japan (Heteroptera: Miridae: Orthotylinae)

Abstract

The plant bug tribe Orthotylini of Japan is revised: 33 species are recognized in 11 genera. Two new genera, Malacocorisella and Pseudoloxopidea, and a new subgenus of the genus Orthotylus, Yamatorthotylus, are described. Thirteen new species are described: Orthotylus (O.) fuscipennis, O. (O.) japonicus, O. (Yamatorthotylus) xanthopoda, Blepharidopterus striatus, Dryophilocoris lucidus, D. miyamotoi, Zanchius quercicola, Z. nakatanii, Z. ryukyuensis, Z. takahashii, Z. gigantoculus, Malacocorisella endoi, and Pseudoloxopidea pinicola. Other known taxa are diagnosed and/or redescribed, and three species, Orthotylus (O.) kurilensis Kerzhner, O. (Melanotrichus) parvulus Reuter and Pseudoloxops imperatorius Distant, are reported from Japan for the first time. The female of Mecomma japonica Miyamoto is also documented. Brief notes on biology are given for 26 species. Photographs of 23 species and a key are also provided.
