Lithodidae from the Ross Sea, Antarctica, with descriptions of two new species (Crustacea: Decapoda: Anomura)
The lithodid crab fauna of the Ross Sea, Antarctica, comprises three species in two genera. Two species are new to science: Neolithodes yaldwyni sp. nov. and Paralomis stevensi sp. nov. Neolithodes yaldwyni, previously misidentified from off the Balleny Islands in the Ross Sea as N. brodiei, is morp...
