Abstract

Four new species of Muricidae are described from New Caledonia, Papua New Guinea and Indonesia and compared with related species. One Timbellus species was collected in New Caledonia. Two other species are described from Papua New Guinea, respectively in Chicopinnatus and Dermomurex. The fourth species, also belonging in Chicopinnatus, originates from Indonesia.

... Discussion. In a discussion preceding the description of a new Dermomurex species (Houart, 2015) I pointed out the difficulty to separate Dermomurex s.s. from Dermomurex (Trialatella). ...
... Although the new species described here could fit in Trialatella with its three varices on the last whorl and a shorter spire, its siphonal canal is obviously shorter than typical Trialatella species. Therefore the decision was taken here to describe this new species as I did earlier (Houart, 2015), without any subgeneric distinction. Axial sculpture of teleoconch whorls consisting of high, narrow varices, more strongly developed on shoulder, connecting varices of previous whorls. ...

A new species of Chicomurex that was confused with C. superbus (Sowerby, 1889) in several publications is described from Taiwan and C. problematicus (Lan, 1981) is considered a junior subjective synonym of C. superbus. The holotypes of both C. superbus and C. problematicus are illustrated and C. superbus is redescribed.

Four species of Chicomurex are discussed and illustrated. Two new species are described from the Philippines, with geographical distribution extending to New Caledonia for one. Chicomurex gloriosus (Shikama, 9177) s ierinstated sa aavlid anme nad C. venustulus (Rehder & Wilson, 1975) is restricted to the Marquesas Islands. Seven species are listed from the Philippines.

Recent deep-sea explorations in the South Pacific have documented around New Caledonia the most diverse fauna of gastropods of the family Volutomitridae anywhere in the world. Fourteen species (nine new, two remaining unnamed) are recorded, all essentially confined to the 250–750 m depth range. The high number of species in the New Caledonia region does not appear to be an effect of sampling intensity, but appears to result from four factors: regional spatial heterogeneity, frequency of hard substrates, syntopy, and a historical heritage shared with Australia and New Zealand, which until now ranked as the major centre of volutomitrid diversity. In the New Caledonia region, volutomitrids show a marked preference for hard bottoms and up to three species may co-occur in the same dredge haul. Many species appear to have extremely narrow geographical distributions within the region (e.g. a single seamount or a single submerged plateau); conversely, Microvoluta joloensis, the only non-endemic volutomitrid present in New Caledonia, ranges from the Mozambique Channel to Tonga.

The Columbariinae have been represented in the fauna of New Zealand from the Paleocene until the Recent, providing the longest known continuous record for the subfamily. Seven living species, representing the genera Columbarium, Coluzea, and Fulgurofusus, are recognized, and include two species, Fulgurofusus maxwelli and Fulgurofusus marshalli that are described as new. The New Zealand columbariine fauna is unusually diverse at the generic level, and includes the largest members of the subfamily, as well as the only primarily sublittoral species. The morphology, anatomy, and distri-bution of the living species are discussed, as are their relationships to living and fossil congeners.

With over 1600 extant described species, the Muricidae are one of the most species-rich and morphologically diverse families of molluscs. As predators of molluscs, polychaetes, anthozoans barnacles and other invertebrates, they form an important component of many benthic communities. Traditionally, the classification of muricids at specific and generic levels has been based primarily on shells, while subfamilies have been defined largely by radular morphology, although the composition and relationships of suprageneric groups have never been studied exhaustively. Here we present the phylogenetic relationships of 77 muricid species belonging to nine of the ten currently recognized subfamilies, based on Bayesian inference and Maximum Likelihood analyses of partial sequences of three mitochondrial (12S, 16S and COI) and one nuclear (28S) genes. The resulting topologies are discussed with respect to traditional subfamilial arrangements, and previous anatomical and molecular findings. We confirm monophyly of each of the subfamilies Ergalataxinae, Rapaninae, Coralliophilinae, Haustrinae, Ocenebrinae and Typhinae as previously defined, but earlier concepts of Muricinae, Trophoninae and Muricopsinae are shown to be polyphyletic. Based on our phylogenetic hypothesis, a new arrangement of these subfamilies is proposed.

The present paper reports on new species and new geographical range extensions, resulting from recent expeditions conducted by ORSTOM, Nóumea, the Muséum National d’Histoire Naturelle, Paris, the Australian Museum, Sydney, the Western Australian Museum, Perth, and the Natal Museum, Pietermaritzburg. The following new taxa are described: Pterynotus stenostoma (New Caledonia), Pterynotus crauroptera (New Caledonia), Pazinotus spectabilis (Loyalty Ridge), Muricopsis charcoti (New Caledonia), Muricopsis bargibanti (Chesterfield Reefs), Muricopsis diamantina (Western Australia), Typhis westaustralis (Western Australia), Typhis trispinosus (Queensland, Australia), Typhis insolitus (New Caledonia), Siphonochelus lozoueti (New Caledonia), Trophon lacrima (New Caledonia), Trophon tirardi (New Caledonia), and ?Trophon aberrans (Queensland, Australia). Three species, Pterynotus fulgens Houart, 1988, Muricopsis auratus (Kuroda & Habe, 1971), and Siphonochelus tillierae Houart, 1986, are new records for southern Africa.

The Muricidae includes about 2500 Cenozoic and Recent species. One characteristic of this radiation is its large sculptural diversification. Therefore, the shell features were used for the supraspecific classification, until anatomical studies suggested that they represent a morphological pitfall, because of their propensity to be homoplastic. However, an overlooked problem in this reconsideration is the accuracy of the shell descriptions, which generally lack ontogenetic data and precise homologies. This paper is focused on the definition of structural homologies through the spiral cords. An analytical approach emphasizes the necessity of three preliminary tests before plausibly defining them. Three main sequences of appearance of cords differing in their mode of insertion on the shell are recognized using the ontogenetic correspondence. This powerful test demonstrates that cords may evolve independently and ontogenetic changes represent a pitfall when attempting to homologize them by using the adult morphology. The topological correspondence allows identifying cords within the two major sequences and is completed by a conjunction test in order to compare all members of the family. The related characters are divided into a cord group and a groove group. Their analysis shows that differences in the expression of cord, cord spines or nodules may exist in spite of a same topological position. It also confirms that labral spines of a same type are not always homologous. Finally, the proposed method suggests that much progress is expected in order to fully understand the morphogenesis of sculptural changes characterizing this gastropod radiation.
