Sea slugs (Gastropoda: Heterobranchia) from two remote reefs of the Southern Gulf of Mexico: Cayo Arenas and Cayo Arcas

Description
Summary:Two field trips were made during 2017 to Cayo Arenas and Cayo Arcas, southern Gulf of Mexico. Direct and indirect sampling methods focused on shell-less marine heterobranchs were carried out. As a result, 30 species of sea slugs are reported for the first time from these 2 remote reefs off the Yucatán Peninsula. From these, 7 species hold new distribution records for the Gulf of Mexico: Sclerodoris worki, Platydoris angustipes, Polycera odhneri, Hexabranchus morsomus, Limenandra nodosa, Petalifera ramose, and Hermaea cruciata. Hexabranchus morsomus is a considerable west geographical range extension from the known distribution range, so far restricted to the Caribbean Sea. Nine specimens were identified up to genus level: Cuthona sp., Haminoea sp., Petalifera sp. and Elysia sp. With the present contribution, the sea slug richness in the Campeche Bank increases to 94 species.
