THE PORCELLANID CRABS OF THE ISLA GORGONA, PACIFIC COAST OF COLOMBIA, WITH A DESCRIPTION OF CLASTOTOECHUS GORGONENSIS SP. NOV. (CRUSTACEA: ANOMURA)

Bernd Werding, Janet Haig

Abstract


A collection of porcellanid crabs was made on the Isla Gorgona, Colombia, during a one week period, sampling as completely as possible a number of different biotopes. The majority of the 16 species in six genera that were collected occurred in the formations of pocilloporid corals and between stones in the sublittoral zone.

Clastotoechus gorgonensis sp. nov. lives in the burrows of the sea urchin Echinometra vanbrunti A. Agassiz in the intertidal zone. Seven species are new additions to the porcellanid fauna of Gorgona and two of them are new records for Colombia. A total of 18 species are now known to occur on Isla Gorgona.
