Acanthochondria serrani sp. n. (Copepoda: Chondracanthidae) parasitic on Serranus auriga (Perciformes: Serranidae) from Argentinean waters

Abstract

A new species of Acanthochondria Oakley, 1927 (Copepoda, Poecilostomatoida, Chondracanthidae), parasitic on Serranus auriga (Cuvier) from the Argentinean coastal zone, is described and illustrated. The new species differs from its congeners by the relative length of the neck and the protopod of leg 2. This is the second record of this genus for the South-eastern Atlantic and the first one from a serranid host.
