Abstract

Four new species of the genus Callistethus Blanchard, 1851, including C. sinocontinentalis Zhao, sp. nov., C. abditus Zhao, sp. nov., C. huadongensis Zhao, sp. nov. and C. setimarginatus Zhao, sp. nov., are described mainly from the Chinese mainland. The identity of C. plagiicollis (Fairmaire, 1886) is clarified, and C. impictus (Bates, 1888) is resurrected as a valid species through examination of type material. Callistethus chrysochroma (Arrow, 1917) comb. nov. and C. xanthochroma (Arrow, 1917) comb. nov. are transferred from the genus Anomala Samouelle, 1819 to the genus Callistethus. Lectotypes are designated for C. plagiicollis, C. impictus, C. xanthochroma, and C. xanthonotus (Arrow, 1917). Callistethus isidai Miyake, 1987 stat. rev. and C. planicauda Fujioka & Kobayashi, 2012 stat. nov. are elevated from subspecies to species.
