Twenty new species of the family Marginellidae are described; one belonging to the genus Hyalina Schumacher, 1817, three Prunum Herrmannsen, 1852 and sixteen Volvalrina Hinds, 1844. This species were collected in the islands of Cuba, Martinique, Guadeloupe and Curaçao. Additionally, the holotype of Volvarina albolineata (d'Orbigny, 1842), a controversial species originally described from Cuba, is herein illustrated and seven species cryptic with it are proposed as new to science, within the sixteen new Volvarina.

From samples of EratoideaWeinkauff, 1879 collected during the MADIBENTHOS 2016 expedition, the importance of the contribution of d’Orbigny for the knowledge of the molluscs of Martinique and the difficulties for the correct taxonomic identification of E. sulcata (d’Orbigny, 1842) is discussed. Orbigny, 1842). Two new species of the genus are also proposed.

A systematic inventory of the sea slugs collected during the expedition Karubenthos-2012, in Guadeloupe island (Karukera), is herein presented. It includes a total of 117 species; 97 Opisthobranchia and 20 Sacoglossa; 85 of them are recorded for the first time. Previous records of other species not collected in the campaign are added to the catalog, which includes a total of 127 species, 42 of them illustrated. Additionally, a new species of Dendrodoris Ehrenberg, 1831, is described and specimens of Paradoris indecora (Marcus, 1970) and three different species of Doto Oken, 1815 collected for the first time in Guadeloupe, are studied in detail: Doto awapa Ortea, 2001, Doto curere Ortea, 2001 and Doto torrelavega Ortea & Caballer, 2005.

The use of the internal shell of the Cephalaspidea belonging to the Family Aglajidae is proposed as critical systematic character to distinguish taxa. The shell of 11 Atlantic species is herein illustrated.

A systematic list including 23 species of sea slugs, 18 opisthobranchia and 5 saco-glossa, recorded for the first time in Guadeloupe Island, is herein presented. These species were collected during the expedition Karubenthos-2012 (may and December 2012) hosted by the National Museum of Natural History in Paris. Additionally, 1 new genus and 8 new species (6 opisthobranchia and 2 sacoglossa) are described. With this contribution, the inventory of the sea slugs from Guadeloupe raises to 149 species, 9 of them newly described.

The synonymy of Peltodoris nayarita Ortea & Llera, 1981, from the Pacific coast of America, is discussed with its Atlantic congener P. greeleyi MacFarland, 1966. In this paper we propose to maintain both of them as separated species within the genus Diaulula Bergh, 1874.

In the most recent molecular phylogeny of the Aglajidae, the Caribbean species Aglaja felis Marcus & Marcus, 1970 was transferred to the Japanese genus Nakamigawaia Kuroda & Habe in Habe, 1961 without justification or support. The assumed N. felis was used as the only representative of the genus in the phylogeny, which did not include the type species: Nakamigawaia spiralis Kuroda & Habe in Habe, 1961. The material determined as A. felis came from Bahamas, Papua New Guinea and Philippines and the conclusion was that they were a complex of species; the Indo-Pacific ones possibly new and all of them belonging to the genus Nakamigawaia. Nonetheless, a simple comparison of shells of the type species of Aglaja Renier, 1881 and Nakamigawaia with A. felis, shows remarkable and supra-specific differences. Thus, in absence of N. spiralis, Nakamigawaia would not be represented in the phylogeny of the Aglajidae, but a distinct taxa, distributed in the Caribbean and the Indo-Pacific. Migaya Ortea, Caballer & Espinosa new genus, is proposed to relocate A. felis. This genus is characterized by bearing sensorial bristles on the head, by its internal shell and supported by the molecular phylogeny. In the same phylogeny, the genus Chelidonura A. Adams, 1850 was fragmented in several independent clades, one of them, characterized by the shell bearing a crest in the protoconch. Two new species of this clade are described in this paper. The shell can be very helpful to assign the right names in the Aglajidae and using it is recommended even in papers where the molecular techniques are applied. A visual analysis of the usefulness of the shell within the group is performed using the established phylogeny as a frame for comparison.

Three different species of the genus Lapinura Marcus & Marcus, 1970 are separated from exemplars collected in the islands of Cape Verde and insular Caribbean. One of it is associated with Lapinura divae Marcus, 1963, type specimen of the genus, and the other two are described as new: L. josemeloi, from the islands of Cape Verde, and L. aestus, from the continental Caribbean of Costa Rica. On three species, Data about their internal anatomy, outer shell, gill and coloring of living animals are provided.
