Abstract

The water penny beetles (Coleoptera: Psephenidae) of the Korean Peninsula are reviewed based on their external morphology and mitochondrial cytochrome c oxidase subunit I gene sequences. Four subfamilies, four genera, and four species, including a new species described herein, are recognized: Eubrianax ramicornis Kiesenwetter, 1874 (Eubrianacinae), Homoeogenus coreanicum sp. nov. (Eubriinae), Malacopsephenoides japonicus (Masuda, 1935) (Psephenoidinae), and Mataeopsephus japonicus (Matsumura, 1916) (Psepheninae). The psephenid subfamily Eubriinae and the genus Homoeogenus Waterhouse, 1880 are here recorded from the Korean Peninsula for the first time. Analyses of the cytochrome c oxidase subunit I gene sequences of larvae and adults of the four Korean species produced a bootstrap support of 100% for each species. Descriptions, habitat data, habitus photographs, line-drawings of male genitalia, and keys to the adults and larvae of the Korean species of Psephenidae are provided.
