摘要

A new species of marine Halacaridae, Copidognathus laeuisetosus is recorded from Yeongdeok coast, Korea. In morphological aspects, the present new species is closely related to C. koreanus Chatterjee and Chang, Morphological similarities and dissimilarities between them are discussed. Copidognathus cerberoideus Bartsch is reported here for the first time from Korea and away from its type locality. Halacarid fauna is poorly known in Korea. Once a freshwater halacarid mite Soldcmellonyx chappuisi Walter, 1917 was reported from the pools in Kosi-gul cave by Imamura (1968) Quite recently, two new marine halacarid species were described by the present authors (Chatterjee and Chang, 2003, 2004): Copidognathus koreanus Chatterjee and Chang, 2003 from Yeongdeok coast and Jejudo Island, and Simognathus coreensis Chatterjee and Chang, 2004 from Yeongdeok coast. In this paper, we deal with another new species and a known species belongs to the genus Copidognathus from South Korea.
