COSTA RICA: Las Gemelas Seamount, near Isla del Coco, leg. Greg Rouse, Avery Hiley, R/V Falkor , ROV SuBastian dive S0225 S7, 20.i.2019, 4.97945°N, 87.45870°W, 637 m: 1 F 14.5 mm (SIO-BIC C13948). Genetic data COI , 16S rRNA and 28S rRNA. Distribution Chile, Perú from 280- to 800-m depth and Costa Rica at 637- m depth. Remarks Munidopsis barrerai is newly recorded from Costa Rica. The general morphology of the specimen collected from Costa Rica agrees with the species described by Bahamonde (1964) and Guzman and Sellanes (2015) . Unfortunately we did not have material from Chile for genetic comparisons between populations.
