Abstract

A new genus and new species of trapeziid crab, Hexagonaloides bathyalis, is described from Okinawa, Ryukyu Islands (Okinawa Prefecture), Japan, on the basis of two male specimens collected at a depth of 247 m. The new genus is unique among the Trapeziidae in having a combination of the hexagonal carapace bearing a single lateral spine and a smooth frontal margin and the unarmed anterior margin of the cheliped meri. The symbiotic association of the new taxon remains unknown.
