A new deep-sea crab, genus Chaceon, from the Austral Islands, southwestern Pacific Ocean (Decapoda: Geryonidae)

Abstract

Chaceon australis, the sixth species of the genus recorded from localities in the Pacific Ocean, is described. It most closely resembles C. poupini Manning, from the Marquesas Islands, but has a smoother carapace, shows differences in relative distances between the anterolateral teeth of the carapace, has a distal spine on the merus of the walking legs, and has a different color in life.
