Two remarkable new species of Prothemus Champion from China and Thailand with comments on their systematic status (Coleoptera Cantharidae)

摘要

Two remarkable new cantharid species were described, Prothemus laticornis >sp. n. (CHINA: Yunnan) and Prothemus lycoceroides >sp. n. (THAILAND: Chiang Dao), and provided with illustrations of aedeagi, ultimate abdominal sternites and antennae of both sexes. Their systematic status was discussed, because they differed from all other species of Prothemus in the dilated and/or serrate antennae and elytra with distinct longitudinal costae and longer pubescence.
