Three new species of Nesidiocoris Kirkaldy from Japan, with a taxonomic review of the tribe Dicyphini for eastern Asia (Heteroptera: Miridae: Bryocorinae)

Abstract

The fauna of the bryocorine plant bug tribe Dicyphini in eastern Asia (including Japan, Korea, Russian Far East and Taiwan) is reviewed, with emphasis on the genus Nesidiocoris Kirkaldy, which is rediagnosed and discussed. Twelve species in six genera are now recognized. Three new species of Nesidiocoris are described from Japan: Nesidiocoris nozakianus sp. n., N. okinawanus sp. n. and N. simotukensis sp. n. Nesidiocoris poppiusi (Carvalho) is proposed as a junior synonym of N. tenuis, and N. plebejus (Poppius) is transferred to Singhalesia China & Carvalho. An annotated checklist and a key to genera and species are also provided to aid in appreciating the east Asian dicyphine fauna.
