Abstract

A single ovigerous female of Parapinnixa cortesi, a new species, was collected from the calcareous tube of an unidentified serpulid polychaete on Isla del Coco, Costa Rica. The new species most closely resembles P. glasselli Garth, 1939, P. hendersoni Rathbun, 1918, and P. nitida (Lockington, 1876), but it can be distinguished from these and all other members of the genus by the morphology of the chelae and the proportions of the carapace.
