A revision of Japanese elasmostethus Fieber (Heteroptera: Acanthosomatidae)

Abstract

The Japanese species of the genus ElasmostethusFieber are revised. Eight species are recognized, including four new species: E kerzhneri, E. hasegawai, E. amabilis and E. rotundus. E. brevis Lindberg is recorded from Japan for the first time. The species previously recognized in Japan as E. minorHorváth is found to be the undescribed species E. kerzhneri. Host plant association is confirmed for the most species. A key to the Japanese species is provided.
