New records of marine molluscs for the northeastern coast of Cuba | Nuevos registros de moluscos marinos para la costa nororiental de Cuba

English. Recently, several studies on Cuban marine molluscs have been developed. However, it is necessary to conduct studies on their distribution, particularly in the poorly studied eastern coasts. In the present work, we collected and identified marine molluscs from the northeastern coast of Cuba. A checklist with 88 species, which are new records to the area, is presented; 59 species are gastropods, 27 are bivalves and two are chitons. Conside- ring previous studies, 375 species have been recorded from this region. The localities with the higher number of recorded species are Playa Esmeralda - Playa Guardalavaca (232 species, 46 new records) and Bahía de Naranjo (107 species, 17 new records). Further stu- dies have to be conducted in other localities of the area, particularly in coral lagoons and bays, and focused on micromolluscs, sea slugs and families with a high number of local endemics (Columbellidae, Marginellidae, and Cystiscidae).   Received: 16-12-2021 Accepted: 07-06-2022 Editor: José A.

Es presentada una lista anotada de 88 especies, que son nuevos registros para el área; 59 especies son gasterópodos, 27 son bivalvos y dos son quitones. Considerando los estudios anteriores, 375 especies han sido registradas de esta región. Las localidades con mayor número de especies registradas son Playa Esmeralda - Playa Guardalavaca (232 especies, 46 nuevos registros) y Bahía de Naranjo (107 especies, 17 nuevos registros). Estudios futuros deben ser conducidos en otras localidades del área, particularmente en lagunas coralinas y bahías, y con énfasis en micromoluscos, babosas de mar y familias con alto número de endémicos locales (Columbellidae, Marginellidae y Cystiscidae).   Recibido: 16-12-2021 Aceptado: 07-06-2022 Editor: José A.
