Abstract

A new species of Gecarcinidae MacLeay, 1838, Johngarthia cocoensis n. sp. from Cocos Island (Costa Rica) is described and illustrated. The new species closely resembles J. malpilensis (Faxon, 1893), from which it can be separated by the inner apical lobes of the third maxilliped meri mostly separated from each other in resting position, palp of third maxilliped merus partly exposed and epistomial carapace tooth completely exposed.
