Three species of the pinnotherid genus Dissodactylus were observed at the northern coast of the Colombian mainland and at Isla Providencia, associated with irregular sea urchins. While D. crinitichelis was previously known to occur at the continental coast of South America, D. rugatus and D. stebbingi are reported for the first time from the southern Caribbean Sea. D. calmani, previously reported from Florida, the Greater Antilles and Virgin Islands is stated to be a junior synonym of D. rugatus. For D. crinitichelis, a new host is reported.
