Stygocyclopia Balearica, a new genus and species of calanoid copepod (Pseudocyclopiidae) from anchihaline caves in the Balearic Islands (Mediterranean)

Abstract Stygocyclopia balearica, a new genus and species of stygobiont pseudocyclopiid calanoid copepod is described from the Balearic Islands (Mediterranean). It was restricted to anchihaline cave waters with salinities of 18 %0 or more. Its close relationship with Paracyclopia FOSSHAGEN, from anchihaline caves on Bermuda suggests a possible tethyan relict distribution. This is the first record of the family Pseudocyclopiidae SARS in Mediterranean waters.
