Collections of porcellanid crabs were made on the Islas del Rosario, Colombia, during a 12-day period, sampling as completely as possible all accessible biotopes. The majority of the 17 species in five genera that were collected did not occur deeper than 2 m and were found in formations of the coral Porites porites (Pallas). A considerable number of species inhabit the intertidal zone.

Petrolisthes rosariensis new species lives mainly in Porites interstices and is described. Parapetrolisthes tortugensis (Glassell, 1945), known previously from Florida, the Bahamas and some Antillean localities, is recorded for the first time from Colombia. A total of 30 species of porcelain crabs are now known to occur on the Atlantic coast of Colombia, representing 86% of the Caribbean and Antillean porcellanid fauna.
