First record of an adult Galapagos slipper lobster, Scyllarides astori, (Decapoda, Scyllaridae) from Isla del Coco, Eastern Tropical Pacific

The Galapagos Slipper lobster, Scyllarides astori, has been reported from rocky reefs along the Eastern Tropical Pacific: the Gulf of California, the Galapagos Archipelago and mainland Ecuador. Although larval stage S. astori has been found in other localities throughout this range, there are no records of adults inhabiting waters between these three locations. Here we present the first record of an adult S. astori from Isla del Coco and Costa Rican Pacific waters. The single specimen, a male, was hand-collected within a coral reef in Pájara islet. This finding increases the reported lobster species richness of Costa Rican Pacific waters to six species and expands the adult geographic range of S. astori to Isla del Coco.
