Caballer M. & Ortea J. 2014. A new sibling species of Notobryon (Gastropoda, Nudibranchia) from the Caribbean Sea. Journal of the Marine Biological Association of the United Kingdom 94(7): 1-6. DOI:10.1017/S0025315414000605
Résumé [+] [-]A new Scyllaeidae of the genus Notobryon is described from Guadeloupe, in the Lesser Antilles. Notobryon caribbaeus sp. nov. is characterized by having the anterior pair of body lobes remarkably bigger than the posterior pair, a stomach with eight triangular plates, a black and very wide ampulla, a lemon-shaped bursa copulatrix and a complex and welldifferentiated sponge-like prostate. The first Caribbean records of Notobryon were provisionally assigned to the Australian species Notobryon cf. wardi and later transferred to Notobryon panamica. However, the structure of the male genital system is one of the main morphological characters to discriminate species in the genus and the presence of a prostate in N. caribbaeus sp. nov. distinguishes it from N. panamica, which remains confined to the eastern Pacific. Of the remaining four species in the world, only Notobryon bijecurum shares this character, but its external anatomy is different: it lacks a bursa copulatrix and the deferent duct is much shorter. Notobryon caribbaeus sp. nov. was captured in the context of an intensive expedition (‘Karubenthos’) organized by the Muse´um National d’Histoire Naturelle, Paris and its description raises the total inventory of sea slugs in Guadeloupe to 150.

Caballer M. & Ortea J. 2015. A New Shallow Water Species of the Genus Philine ascanius, 1772 (Mollusca: Opisthobranchia: Philinidae) from Venezuela. Journal de Conchyliologie 42(1): 33-40
Résumé [+] [-]A new shallow water species of the genus Philine Ascanius, 1772 is described from the coastal lagoons of the Bay of Buche, Venezuela. This species is characterized by the color pattern of its body, yellowish with white dots, the cephalic shield, as long as the posterior shield, the internal shell with the rear posterior edge not surpassing the apex and the sculpture composed of 6 to 18 striking spiral lines, the innermost lateral teeth of the radula, bearing 10–19 denticles in the masticatory margin and by lacking gizzard plates. Philine buchensis new species is compared with all the species of the genus known to date in the Caribbean, particularly withthose from coastal areas (0–10m): Philine sagra (d´Orbigny, 1841) and Philine caballeri Ortea, Espinosa & Moro, 2001.

Caballer M. & Ortea J. 2015. Finishing to untangling the taxonomic knot: new species of the genus Bulbaeolidia Carmona, Pola, Gosliner & Cervera, 2013 (Mollusca: Aeolidiidae) from the Caribbean and Galapagos. Revista de la Academia Canaria de Ciencias 27: 113-123
Résumé [+] [-]The nudibranch gastropod genus Aeolidiella Bergh, 1867 has been found to be polyphyletic. It holds an unnamed clade that was named Bulbaeolidia Carmona, Pola, Gosliner & Cervera, 2013. This genus is composed by four species, two of them unnamed: Bulbaeolidia alba, from Japan,Malaysia and Philippines, Bulbaeolidia japonica, from Japan, Bulbaeolidia sp. B, from Hawaii, and Bulbaeolidia sp. A, from Brazil. Bulbaeolidia was described in the context of a molecular phylogeny, thus, no “taxonomic action” regarding to the unnamed species was taken, leaving the work incomplete, and the 50 % of the members of Bulbaeolidia undescribed. In this paper we describe the Western Atlantic member of the genus Bulbaeolidia and a Pacific species from Galapagos, both cryptic with Bulbaeolidia alba (Risbec, 1929).

Caballer M. & Ortea J. 2015. The first species of Spiniphiline Gosliner, 1988 (Gastropoda: Cephalaspidea) in the Atlantic Ocean, with notes on its systematic position. Journal of Molluscan Studies 82(1): 122–128. DOI:10.1093/mollus/eyv041
Résumé [+] [-]The Indo-Pacific genus Spiniphiline Gosliner, 1988 was erected for a rare species of Cephalaspidea characterized by an internal shell with spines. Spiniphiline kensleyi Gosliner, 1988 was until now the only known species. During the ‘Karubenthos’ expedition to the archipelago of Guadeloupe (Lesser Antilles, Caribbean Sea) coordinated by the Muse´um national d’Histoire naturelle, Paris, a small philinid was captured on a ma¨ erl bed. This specimen is here described as a new species of Spiniphiline—S. persei. Its occurrence in Guadeloupe is the first record of the genus in the Atlantic Ocean. The systematic position of Spiniphiline is discussed and evidence given for its inclusion in the family Philinidae s. s.

Fedosov A.E., Caballer gutierrez M., Buge B., Sorokin P.V., Puillandre N. & Bouchet P. 2019. Mapping the missing branch on the neogastropod tree of life: molecular phylogeny of marginelliform gastropods. Journal of Molluscan Studies 85(4): 439-451. DOI:10.1093/mollus/eyz028
Résumé [+] [-]Marginelliform gastropods are a heterogeneous and diverse group of molluscs encompassing over 1,600 living species, among which are the smallest known neogastropods. The relationships of marginelliform gastropods within the order Neogastropoda are controversial, and the monophyly of the two marginelliform families the Marginellidae J. Fleming, 1828 and the Cystiscidae Stimpson, 1865, remains unconfirmed. DNA sequence data have never been used to assess the relationships of the marginelliform gastropods, making this group the only major branch missing in our current understanding of the neogastropod tree of life. Here we report results of the first multilocus phylogenetic analysis of marginelliform gastropods, which is based on a dataset comprising 63 species (20 genera) of Marginellidae and Cystiscidae, and a wide range of neogastropod lineages. The Marginellidae and Cystiscidae form a moderately supported clade that is sister to the family Volutidae. Marginellona gigas appears to be sister to all other marginelliforms. The subfamily Marginellinae was recovered as a well-supported clade, and good resolution of this part of the tree makes it possible to propose amendments to the family-level classification of the group. The relationship between Granulina and other marginelliforms could not be resolved and requires further study. Due to poor resolution of basal relationships within the Marginellidae–Cystiscidae clade, the monophyly of the Cystiscidae was neither confirmed nor convincingly rejected. The shell morphology of most marginellid and cystiscid genera is taxonomically not very informative but, nevertheless, of the traditionally recognized genera only Gibberula and Dentimargo were shown to be polyphyletic. Although a comprehensive systematic revision of the group requires more extensive taxonomic sampling (e.g. with better representation of the type species of nominal genus-group names), our results support the superfamily Volutoidea, comprising four families (Volutidae, Cystiscidae, Marginellidae and Marginellonidae), with the placement of the Granulinidae uncertain for the time being.

Ortea J., Moro L. & Caballer M. 2014. Contribución al estudio de la familia Pleurobranchidae Gray, 1827 (Mollusca: Opisthobranchia) en la Macaronesia y las islas Galápagos. Vieraea 42: 117-148
Résumé [+] [-]All the species of the genres Pleurobranchus Cuvier, 1804 and Berthellina Gardiner, 1936 described or cited in the Macaronesia are revised. The records of Pleurobranchus areolatus Mörch, 1863 in the Canaries are transferred to Pleurobranchus crossei Vayssiere, 1896. Pleurobranchus lowei Watson, 1897, from Madeira, is synonymized with Berthellina edwardsi (Vayssiere, 1896). The name Pleurobranchus garciagomezi Cervera, Cattaneo & Edmunds, 1996 is applied to the specimens, endemic to Cape Verde, that match in the chromatic pattern of the holotype of this species. Pleurobranchus wirtzi, new species, is described to include the rest of the specimens from other islands in the Macaronesia, identified in the literature as P. garciagomezi. Two new species of Berthella Blainville, 1828 and Berthellina are described from Cape Verde and compared with two Caribbean taxa, Pleurobranchus evelinae Thompson, 1978 and Berthellina quadridens (Mörch, 1863). New anatomical data are given on the latter. In addition, the Pleurobranchidae from Galapagos obtained in the expeditions organized by the “Museo de Ciencias Naturales de Tenerife” in Tenerife is studied, given that two Atlantic species, Pleurobranchus areolatus and Berthellina engeli Gardiner, 1936, have been recorded there.

Ortea J., Caballer M., Moro L. & Espinosa J. 2014. What the shell tells in Aglajidae: a new genus for Aglaja felis (Opisthobranchia: Cephalaspidea). Revista de la Academia Canaria de Ciencias 26: 83-119
Résumé [+] [-]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.
