The kinorhynch genus Paracentrophyes currently consists of two species only: P. quadridentatus (Zelinka,
1928) from the Mediterranean Sea and P. praedictus Higgins, 1983 from Belize in the Caribbean. Both species have until
now been recorded from their type localities only. In the present contribution a new species of Paracentrophyes, P.
anurus sp. nov., is described from the Korea Strait. The species can be recognized by details in the mouth cone
morphology, absence of perispinal setae in segment 10, and absence of a midterminal process in both sexes. Female
specimens are furthermore characterized by the presence of an extraordinary long middorsal spine on segment 10,
whereas males possess a midterminal type 3 sensory spot. Besides the recording of the new species, the occurrence of P.
cf. quadridentatus is reported from two localities in the Atlantic Ocean (Faeroe Islands and Spain). The recorded
specimens are described in detail, based on combined examinations with LM and SEM, and diagnostic traits for all three
species of Paracentrophyes are discussed in light of the newly acquired information. Furthermore, an emended
terminology for positions of cuticular trunk structures is proposed.
