Miters including Mitra chinensis are important fishery resources in China. However, the phylogenetic and taxonomic studies in Mitridae have been limited. In this study, we report the first complete ...mitochondrial genome of M. chinensis. The mitogenome has 16,238 base pairs (66.9% A + T content) and is made up of a total of 37 genes (13 protein-coding, 22 transfer RNAs, and two ribosomal RNAs), plus a putative control region. This study will provide useful molecular resources for addressing taxonomic and evolutionary issues in Neogastropoda.
We describe
sp. n. (Gastropoda: Mitridae), collected on the summit of seamounts (~200 m water depth) in the vicinity of Desventuradas Islands, Chile insular territory. Additionally, we provide some ...insight into the habitat of this new species based on underwater imagery taken with a remotely operated vehicle.
sp. n. is characterized by its small size (up to 26 mm), elongate-ovate shape, solid shell and smooth appearance. It has a base brown color, with some specimens being tan or yellow. It is morphologically related to counterparts from shallow depths on the west coast of North, Central and South America (i.e.,
,
and
), but has no affinities with species of the family reported from around Easter Island, on the far western side of the Salas y Gómez ridge (e.g.,
,
and
), or with other Indo-Pacific species. The present contribution adds to the knowledge of the poorly studied fauna of the seamounts in the southern portion of the Nazca ridge and easternmost section of the Sala y Gómez ridge, an area characterized by the high degree of endemism of its benthic fauna, and now protected within the large and newly created Nazca-Desventuradas Marine Park.
Three new species of Family Mitridae (Mollusca: Gastropoda) from the South China Sea are described in the present paper. They are Ziba aglais sp. nov. B. LI & S. ZHANG, Neocancilla daidaleosa sp. ...nov. B. LI & X. LI, and Mitra holkosa sp. nov. B. LI. Their systematic positions are also discussed.
A preliminary checklist of the marine gastropod molluscs of Moreton Bay is presented, based on the collections of the Queensland Museum, supplemented by records from the Moreton Bay Workshop (2005), ...published literature and unpublished field records. 1023 species have to date been recorded from the bay area (Caloundra to the Gold Coast including bay islands, to 50 metres depth) representing 138 families and 446 genera. Dominating, in terms of species numbers, are caenogastropod 'prosobranchs' with 672 species (65% of the faunal total) most of which are carnivorous. In contrast, patellogastropods (true limpets), vetigastropods (trochids, turbinids and allies) and neritimorphs, despite containing some of the most abundant species of bay gastropods, constituent less than 8.0% of the total species count. The larger groups of caenogastropods are the Muricoidea (murex shells and allies, 100 species or 9.8% of faunal total), Conoidea (cones, terebrids and turrids: 122 species or 11.9%), Cypraeoidea (cowries and allies), Triphoroidea (triphorids plus cerithiopsids) and Buccinoidea (true whelks) - these three groups each with just over 70 species (each approximately 7.0% of the faunal total). Next in size to the Caenogas-tropoda is the Heterobranchia (opisthobranchs sensu lato plus pulmonates) with 273 recorded species (approximately 26% of faunal total), dominated by a large nudibranch component (145 species, almost half of which are doridoideans). The number of gastropod species that actually occur within Moreton Bay is unknown and likely to remain so until the appropriate taxonomic work and supplementary collecting are carried out. Certain families, such as the Cypraeidae (cowries), Ovulidae (allied cowries), Strombidae (strombs), Mitridae (mitres), Ranellidae (tritons) and Conidae (specifically subfamily Coninae -- cone shells) are very well documented thanks largely to their popularity with collectors and/or specialists. Other groups, notably the small-shelled 'turrids', the various rissooidean families and pyramidellid heterobranchs almost certainly have significant numbers of unrecorded or undescribed species living in the bay, and hence such groups should be targeted in future studies. The impressive diversity of the bay gastropod fauna undoubtedly reflects the physical complexity of the region and the wide range of available habitats (sandflats, mudflats, seagrass areas, mangroves, rocky reefs, coral reefs).
New additions to the Japanese marine molluscan fauna are here recorded : Neocancilla kayae Cernohorsky, 1978, hitherto known only from the Hawaiian Islands, Vexillum (Costellaria) delicatum (A. ...Adams, 1853) known from the tropical Indo-West Pacific, and V. (Nodicostellaria) sauternesense Suduiraut, 1997 known from the Philippines. V. (Pusia) charlesi n. sp. was previously known only as an undescribed species from the Philippines, but has recently also been found in Japan and is here described. Thala maxmarrowi Cernohorsky, 1980, originally described from Okinawa, is recorded from the Kii Peninsula, central Honshu.
