The genus Pradoxa Fernandes & Rolán, 1993 (Gastropoda: Muricidae) in SãoTomé, Príncipe and Annobón.
-
The genus Pradoxa is revised and all the species are described, compared and illustrated. Two new species are described from São Tomé, Pradoxa gorii spec. nov. and P. urdambideli spec. nov. The radula is illustrated for P. confirmata (Fernandes & Rolán, 1990), P. thomensis (Fernandes & Rolán, 1990) and P. gorii spec. nov. The subfamilial classification is discussed and a comparative table is added in the appendix.

New species of Muricidae (Gastropoda) and additional or noteworthy records from the western Pacific.
-
Fourteen species of Muricidae referable to the (sub)genera Promurex Ponder & Vokes, 1988, Pygmaepterys Vokes, 1978, Murexsul Iredale, 1915, Pazinotus Vokes, 1970, Prototyphis Ponder, 1972, Ponderia Houart, 1986, Gemixystus Iredale, 1929, Leptotrophon Houart, 1995 and Scabrotrophon McLean, 1996 are reported from New Caledonia, the Solomon Islands and Taiwan, to depths down to 1750 m. Five new species are described: Favartia (Pygmaepterys) lifouensis n. sp. from New Caledonia with range extension to the Solomon Islands, Pazinotus chionodes n. sp. and Gemixystus calcareus n. sp. from New Caledonia, Leptotrophon wareni n. sp. from the Solomon Islands and Favartia (Pygmaepterys) circinata n. sp. from Taiwan.

Cenozoic evolution of Muricidae (Mollusca, Neogastropoda) in the Southern Ocean, with the description of a new subfamily
-
Gastropods are among the most studied group in Antarctica, and taxa with an advanced status of systematic knowledge can be used as a model to study how oceanographic and climatic patterns shaped Recent faunal assemblages. Within the ongoing study of the muricid phylogeny, we have analysed molecular and morphological data from species traditionally ascribed to the muricid subfamily Trophoninae. Particularly, the availability of specimens collected in the Southern Ocean and surrounding basins allowed to demonstrate as the genera Pagodula, Xymenopsis, Xymene and Trophonella, which are traditionally classified in the Trophoninae, actually belong to a distinct lineage, for which the new subfamily Pagodulinae is herein introduced. We propose and discuss a possible framework for the origin and radiation of Antarctic muricids.

The Recent Typhinae (Gastropoda: Muricidae) of New Zealand.
-
The Recent Typhinae from the New Zealand region are reviewed. Four species are recognized: Monstrotyphis pauperis (Mestayer, 1916), M. montfortii (A. Adams, 1863), M. tangaroa n. sp. and Siphonochelus solus Vella, 1961. A possible fifth species, known from a single, subadult specimen, remains unidentified.

Description of Two New Species of Trophoninae s.l. and Typhinae (Gastropoda: Muricidae) from New Caledonia and Comments on Litozamia Iredale, 1929 and Siphonochelus Jousseaume, 1880
-
Abstract: Litozamia acares n. sp. and Siphonochelus (Trubatsa) wolffi n. sp. are described from New Caledonia. The radula and the operculum of Litozamia acares are illustrated and described. The classification of Litozamia in Trophoninae is maintained awaiting molecular data to either confirm or modify this decision. Litozamia longior (Verco, 1909) is reinstated as a valid species. The use of the subgenus Choreotyphis Iredale, 1936 is reinstated in Siphonochelus for a single species from eastern Australia, based on differences in shell morphology

The status of the northeastern Atlantic and Mediterranean small mussel drills of the Ocinebrina aciculata complex (Mollusca: Gastropoda: Muricidae) with the description of a new species
-
The northeastern Atlantic and Mediterranean small mussel drills of the Ocinebrina aciculata complex are here revised and consist of at least 3 species. The type species, Ocinebrina aciculata (Lamarck, 1822), characterized by a slender shell with rounded whorls and primary and secondary spiral cords of approximately similar size, lives throughout the northeastern Atlantic and Mediterranean Sea at depths usually ranging between 0 and 105 m. Its synonymy is here stabilized by a neotype selection for Murex corallinus Scacchi, 1836. Ocinebrina corallinoides Pallary, 1912 (=Ocinebrina buzzurroi Cecalupo and Mariani, 2008, new synonymy), characterized by a strongly elongate and weakly convex shell and primary and secondary spiral cords of approximately similar size, is endemic to the Gulf of Gabès and is here considered a distinct species, pending genetic studies. Ocinebrina reinai n. sp. is here described from the central Mediterranean Sea (where it is sympatric with O. aciculata) on the basis of morphological diagnostic features of shell (rarest presence of labral tooth, commoner presence of infrasutural apertural denticle, dark spots on the ribs and spiral sculpture with differently sized primary and secondary cords and smaller threads) and radula, confirmed by genetic data. Divergence in COI sequences with sympatric samples of O. aciculata (>7%), confirm their status as a distinct species. A comparative table reporting diagnostic features of the congeneric species of the complex and those with which the new species was previously misidentified is offered.
