A new species of Philocheras (Crustacea, Decapoda, Caridea, Crangonidae) from southwestern Australia

A new species of crangonid shrimp, Philocheras poorei n. sp., is described and illustrated on the basis of two specimens collected from Albany, southwestern Australia, at littoral depths. Morphologically, the new species appears closest to P. acutirostratus (Yaldwyn, 1960) and P. pilosoides (Stephensen, 1927), both known from New Zealand, but is readily distinguished by the different disposition of the teeth on the carapace and the unarmed ventral margin of the merus of the first pereopod. It is the tenth species of the genus known from Australia, and the fifth possibly representing an endemic element to southern Australia. A key to the species of the genus known from Australia and a checklist of the species from the world are provided.
