“…Thus, molecular distinctions of two otherwise identical abalone species were made using 18S rDNA sequences, while the phylogeny of the six vetigastropod subgroups and Littorinidae were studied based on 18S rRNA sequences [15][16][17]. Using the mitochondrial 16S rRNA gene, the phylogenies of eight species of the genus Buccinum and of 35 species of the family Buccinidae were analyzed by Iguchi et al [18] and by Hayashi [19], respectively. 28S rRNA was also used to evaluate the major adaptive radiation of some buccinid life forms [20].…”

A phylogenetic analysis of members of the family Buccinidae was conducted using 18S rRNA gene, 28S rRNA gene and the mitochondrial cytochrome oxidase I gene. We studied 18 species of Buccinidae that belong to eight different genera and inhabit the China coastal seas. We analyzed the patterns of divergence between an outgroup and basal ingroup taxa, the monophyly of the genus Neptunea, and the position of one unnamed species within the Buccinidae. A phylogenetic tree (neighbor-joining (NJ) method) was reconstructed based on the sequences of 18S rRNA, 28S rRNA and COI, with Rapana venosa as outgroup. The NJ tree indicated that the 18 species could be divided into five groups. The genus Buccinum was monophyletic, whereas Neptunea was shown to be paraphyletic since it included Siphonalia subdilatata and Neptunea sp., a new species. This novel species otherwise clustered consistently with Neptunea cumingi in three other phylogenetic trees, showing a low genetic distance and divergence percentage of sequences belonging to the genus Neptunea. A smaller genetic distance and a smaller difference of 18S rRNA, 28S rRNA and COI sequences between Neptunea cumingii and Neptunea arthritica cumingii confirmed them to be the same species.

Abstract:The Sea of Japan is a marginal sea surrounded by narrow, shallow straits which became isolated from neighboring waters when the sea level fell during the Pleistocene glacial periods. In order to understand the influences of such paleoenvironmental changes on the formation of populations of marine organisms in the Sea of Japan, deep-sea whelks (genera Buccinum and Neptunea (Buccinidae)) are appropriate materials considering their low dispersal abilities through direct development. Deep-sea whelks are also important marine species for fisheries in the Sea of Japan. However, several taxonomical problems due to morphological variations and lack of knowledge about gene flows among local populations in deep-sea whelks may lead to inappropriate fisheries management. We and my collaborators examined the genetic inter-and intraspecific relationships of deep-sea Buccinum and Neptunea species by means of molecular markers with samples from various stations around Japan (mainly from the Sea of Japan). We found some intriguing genetic structures closely related to their characteristic reproductive mode and paleoenvironmental changes in the Sea of Japan. In addition, by comparing inter-and intraspecies relationships of some Buccinum species, I clarified some novel taxonomical aspects of these species. Here, I review these genetic structures of deep-sea whelks and describe the future direction of phylogeographical approaches to deep-sea organisms in the Sea of Japan.

The wide range of morphological variations in the "loxurina group" makes taxa identification difficult, and despite several reviews, serious taxonomical confusion remains. We make use of DNA data in conjunction with morphological appearance and available information on species distribution to delimit the boundaries of the "loxurina" group species previously established based on morphology. A fragment of 635 base pairs within the mtDNA gene cytochrome oxidase I (COI) was analysed for seven species of the "loxurina group". Phylogenetic relationships among the included taxa were inferred using maximum parsimony and maximum likelihood methods. Penaincisalia sigsiga (Bálint et al), P. cillutincarae (Draudt), P. atymna (Hewitson) and P. loxurina (C. Felder & R. Felder) were easily delimited as the morphological, geographic and molecular data were congruent. Penaincisalia ludovica (Bálint & Wojtusiak) and P. loxurina astillero (Johnson) represent the same entity and constitute a sub-species of P. loxurina. However, incongruence among morphological, genetic, and geographic data is shown in P. chachapoya (Bálint & Wojtusiak) and P. tegulina (Bálint et al). Our results highlight that an integrative approach is needed to clarify the taxonomy of these neotropical taxa, but more genetic and geographical studies are still required.
