Taxonomic review of the predatory genus Cryptalaus Ôhira (Coleoptera: Elateridae) from Korea with a new record of C. yamato (Nakane)

Abstract

We studied the taxonomy of the predatory genus Cryptalaus Ôhira (Coleoptera: Elateridae) in South Korea, including two species, C. berus (Candèze) and C. larvatus pini (Lewis), which have been previously reported from South Korea. In the present study, a rare species, C. yamato (Nakane), which had been regarded as endemic to Japan, is discovered in the central region of South Korea for the first time with a DNA barcode (COI) sequence. A key, redescription, distribution map of three Korean species in Asia, and illustrations of the diagnostic characters of the Korean Cryptalaus species are provided.
