Abstract

A sixth species of the genus Paracrangon, P. australis sp. nov. (Crustacea: Decapoda: Crangonidae), is reported from a seamount off southern Australia. The Australian species is unique in having five teeth on the dorsal median margin of the carapace, which is associated with a distinct reticulate structure on the supraventral part. All species of the genus recorded to date have four or fewer teeth on the dorsal median margin of the carapace. The present record is the first occurrence of the genus in the southwest Pacific and greatly extends its known geographical range. A key for identification of all species is presented with data on geographical and bathymetric ranges.
