García J.L., Bautista-guerrero E., Cárdenas P., Cruz-barraza J.A. & Aguilar-camacho J.M. 2018. Molecular and morphological data from Thoosidae in favour of the creation of a new suborder of Tetractinellida. Systematics and Biodiversity 16(5): 512-521. DOI:10.1080/14772000.2018.1457100
Abstract [+] [-]The Thoosidae (Porifera, Demospongiae, Tetractinellida) currently includes the genera Thoosa, Alectona, and Delectona. To this date, molecular data are only available for Alectona. In this study, the phylogenetic affinities of the genera Thoosa and Alectona have been investigated with the species T. mismalolli, T. calpulli, and T. purpurea from the Mexican Pacific using morphology and three molecular loci: the mitochondrial cytochrome oxidase subunit 1 (CO1 mtDNA), 28S rRNA (fragment D2), and 18S rRNA. Morphology and embryology showed that these genera are quite different from the rest of the tetractinellids because larvae of Alectona and Thoosa have unique features in sponges, such as the presence of monaxonic discs in Thoosa and tetraxonic discs in Alectona which disappear in the adult stages. A phylogenetic analysis using selected species from the order Tetractinellida revealed that Thoosa groups with Alectona thus confirming morphological studies. The peculiarities in spiculation and embryology of the Thoosa and Alectona larvae, which are markedly different from species belonging to the suborders Astrophorina and Spirophorina and their distant phylogenetic position (based on three molecular loci), suggest that Thoosidae could be placed in the new suborder Thoosina.

Houart R., Zuccon D. & Puillandre N. 2019. Description of new genera and new species of Ergalataxinae (Gastropoda: Muricidae). Novapex 20(HS 12): 1-52
Abstract [+] [-]The recent genetic analysis of the muricid subfamily Ergalataxinae has led to a better understanding of this subfamily, but some species were left without appropriate generic assignments and the classification of others required revision. This knowledge gap is partially filled herein, with new combinations and the description of three new genera. The examination of new material, along with a careful re-examination of and comparison to existing material, resulted also in the identification of nine new species. These new genera and new species are described herein, lectotypes are designated and new combinations are given. The geographical range of all the new species is provided on maps. All new species are compared with related or similar species. The radula of Morula palmeri Powell, 1967 is illustrated for the first time.

Abstract [+] [-]Four species of Eiconaxius are known to possess a denticulate median rostral carina: E. antillensis Bouvier, 1905, E. asper Rathbun, 1906, E. cristagalli Faxon, 1893, and E. indicus (De Man, 1907). They are reviewed and two similar new species are described: E. dongshaensis sp. nov., and E. gololobovi sp. nov. A key to distinguish them is presented.

Abstract [+] [-]A collection of crabs assembled during the KUW 2009 expedition to Mayotte Island and deposited in the Muséum national d’Histoire naturelle Paris is studied. In total 202 species are recognized, 138 of them being new records for the Island and a list of brachyuran crabs is documented and illustrated with photographs. A complementary list of all crabs previously in taxonomic literature from Mayotte and its nearest Islands (Comoros Islands, Glorieuses Islands and marine banks of Zélée, Geyser and Leven) is also provided. In total 298 crabs are identified from the region, the richness of this fauna is discussed with zoogeographic considerations and the prospects for further studies are outlined.

Rodríguez-flores P.C., Macpherson E. & Machordom A. 2019. Revision of the squat lobsters of the genus Leiogalathea Baba, 1969 (Crustacea, Decapoda, Munidopsidae) with the description of 15 new species. Zootaxa 4560(2): 201. DOI:10.11646/zootaxa.4560.2.1
Abstract [+] [-]The genus Leiogalathea Baba, 1969 currently contains only two benthic species both occurring on the continental shelves and slope: L. laevirostris (Balss, 1913), widely reported in the Indo-Pacific region, and L. agassizii (A. Milne Edwards, 1880), from both sides of the Central Atlantic. A certain degree of morphological variability linked to their geographic distributions was previously noticed, mostly in L. laevirostris. In the present study, we revise numerous specimens collected from the Atlantic, Indian and Pacific Oceans, analysing morphological and molecular characters (COI and 16S rRNA). We found 15 new species; all of them are distinguished from L. laevirostris and L. agassizii by subtle but constant morphological differences and show clear genetic separation. Furthermore, L. imperialis (Miyake & Baba, 1967), previously synonymized with L. laevirostris, was found to be a valid species. All species are described and illustrated. Species of the genus Leiogalathea are morphologically distinguishable on the basis of the spinulation of the carapace, the shape and the armature of the rostrum, the shape of the propodi of the walking legs, and the pattern of the setae covering on rostrum, carapace and chelae. Some species are barely discernible on the basis of these characters but are highly divergent genetically.

Tenorio M.J., Monnier E. & Puillandre N. 2018. Notes on Afonsoconus Tucker & Tenorio, 2013 (Gastropoda, Conidae), with description of a new species from the Southwestern Indian Ocean. European Journal of Taxonomy(472). DOI:10.5852/ejt.2018.472
Abstract [+] [-]Although cone snails are among the most studied group of gastropods, new species are still regularly described. Here, we focus on Afonsoconus Tucker & Tenorio, 2013, a lineage that includes only two species from the Indo-Pacific Ocean. The analysis of molecular (partial mitochondrial cox1 gene sequences) and morphological (shell and radular tooth) characters revealed that the samples collected by dredging in deep water during a recent expedition carried out in the Mozambique Channel are different from the samples collected in the Pacific Ocean. We thus introduce here a new species, Afonsoconus crosnieri sp. nov., from the SW Indian Ocean including records from the Mozambique Channel, the Comoros and Glorieuses Islands, Madagascar, South Africa and Reunion Island.

Vacelet J. & Cárdenas P. 2018. When is an aster not an aster? A new deep-sea Discorhabdella (Demospongiae, Poecilosclerida) with asters, from the Mozambique Channel. Zootaxa 4466: 197. DOI:10.11646/zootaxa.4466.1.15
Abstract [+] [-]Discorhabdella pseudaster n. sp. is an incrusting sponge from the upper bathyal zone of the ‘Banc du Geyser’, north of Madagascar, Mozambique Channel. This new species is described only from a single specimen but it is remarkable by the presence of spicules similar to euasters, a type of microsclere unknown in Poecilosclerida. These spicules are in fact a new example of homoplasy, being derivatives of the typical Discorhabdella pseudoastrose acanthostyles, which are here reduced to the aster-like tyles. The isochelae with a large lamella on the shaft are also quite unique in Poeciloclerida.
