Six new species of Copepoda (Clausiidae, Pseudanthessiidae, Polyankyliidae) associated with polychaetes from Korea

Abstract

Copepods associated with polychaete hosts are relatively rarely reported and one reason for this might be their low prevalence rates (Kim et al., 2013). Nevertheless, polychaete annelids harbor very diverse copepod associates. Eleven families of cyclopoid copepods are recorded exclusively from polychaete hosts, but several other families include one or more species that live in association with polychaetes (Boxshall and Halsey, 2004; Kim et al., 2013). In Korea, twelve species of copepods have been recorded as associates of polychaetes from the intertidal zone and shallow water. They are Hemicyclops ctenidis Ho and Kim, 1990, H. membranus Moon and Kim, 2010, H. nasutus Moon and Kim, 2010, Foliomolgus cucullus Kim, 2001, and Hemadona clavicrura Ho and Kim, 2004 in the Clausidiidae (Ho and Kim, 1990; 2004; Kim, 2001c; Moon and Kim, 2010); Clausia antiqua Kim, 2001, C. lobata Kim, 2000, Likroclausia namhaensis Ho and Kim, 2003, and Rhodinicola laticauda Ho and Kim, 2003 in the Clausiidae (Kim, 2000; 2001b; Ho and Kim, 2003); and Terebelliphilus simplex Kim, 2001, Myxomolgus invulgus Kim, 2001 and Nasomolgus firmus Humes and Ho, 1967 in the Sabelliphilidae (Kim, 1998; 2001a). In this paper six new species are described from Korean waters, three of them belonging in the family Clausiidae, one in the Pseudanthessiidae, and two in the Polyankyliidae.
