Introduction: The genus Leptopentacta has only been previously reported from Florida, Cuba, Colombia, Costa Rica, and Suriname. Objective: To present the first record of the genus for Nicaragua. Methods: The morphological characters of Nicaraguan material at the Smithsonian Institution (USNM 1014529), were corroborated with the original description. Results: The five specimens collected in the Nicaraguan Caribbean match the genus. Conclusions: Leptopentacta is reported for the first time from the Nicaraguan Caribbean Sea. This increases the number of Nicaraguan echinoderms to 194 species.
