Meloscaphander grandis is a little-known species missing from databases and papers on taxonomic revision phylogenetic analysis of Scaphandridae. This redescribed herein, based the type specimen specimens abyssal plain adjacent to Kuril-Kamchatka Trench. A COI, 16S, 28S markers show M. nest within Scaphander clade. Additionally, lignarius S. bathymophilus are suggested be complex cryptic species. Morphological differences between genera dubious significance and, when coupled with molecular...
A new species of the genus Tetrastemma Ehrenberg, 1831, T. freyae sp. nov., is described and illustrated from Hawaii India. The description based on light microscopy examination external internal morphology, as well two gene markers (cytochrome c oxidase subunit I histone H3 DNA).
Between the years 1995 and 2007, 48 nominal genera 128 species of nemerteans were established worldwide. During this period, taxonomic changes such as synonymization, alteration affiliation to higher taxa, resurrection formerly invalid names made for 26 69 species. The between well at genus level, are listed here with their original citations. type depositories since also mentioned. In total, 285 1275 currently recognized valid in phylum Nemertea. Their distribution among taxa is follows:...
A new nemertean species of the genus Cephalothrix from intertidal calcareous red algae off Vietnam coast is described based on histological sections, confocal laser scanning microscopy, and nucleotide sequences three nuclear (18S rRNA, 28S H3) two mitochondrial (COI, 16S rRNA) DNA fragments. suni sp. nov. characterized by a unique body colour pattern consisting transverse brown ventral side. molecular phylogenetic analysis family Cephalotrichidae using multigene approach has identified...
Background It has been suggested that statistical parsimony network analysis could be used to get an indication of species represented in a set nucleotide data, and the approach discuss boundaries some taxa. Methodology/Principal Findings Based on 635 base pairs mitochondrial protein-coding gene cytochrome c oxidase I (COI), we analyzed 152 nemertean specimens using with connection probability 95%. The revealed 15 distinct networks together seven singletons. Statistical yielded three...
Marine heterobranch slugs of the order Runcinida comprise 61 species, most which inhabit Atlantic Ocean and are referred to genus Runcina. The Pacific have been much less studied date: only 12 from genera Metaruncina Baba, 1967, Rfemsia Chernyshev, 1999, Burn, 1963, Runcinella Odhner, 1924, Pseudoilbia M. C. Miller & Rudman, 1968, Runcina Forbes [in Hanley], 1851, described region. Metaruncina, Rfemsia, found in (Baba 1954, 1967; Burn 1963; Gosliner 1991; Chernyshev 1998, 2005, 2006)....
Continued sampling of the latest Eocene to earliest Oligocene Gries Ranch Formation in Lewis County, Washington State, has yielded new heterobranch microgastropod species. Orbitestella kieli sp. nov., is third fossil species this genus and family Orbitestellidae from western North America. Two Ammonicera, A. rolani nov. danieli are together only second record Omalogyridae northeastern Pacific Ocean. New specimens two previously recorded species, O. palaiopacifica Squires & Goedert...
The Kuril Basin and the Kuril-Kamchatka Trench are two interconnected deep-sea ecosystems both located in one of most highly productive regions world’s oceans. main distinguishing features these low oxygen concentration near-bottom water Basin, high hydrostatic pressure trench. We investigated abundance meio- macrobenthic nematodes macrofauna on floor (depths 3,300–3,366 m) area 3,432–9,539 m), as well influence some environmental factors quantitative distribution bottom fauna. This was not...
The proboscis and rhynchocoel musculature of 56 nemertean species was studied using phalloidin labelling confocal laser scanning microscopy. Six types muscle layers are found in the anterior nemerteans: inner circular, diagonal, longitudinal, outer longitudinal. Only circular longitudinal present all nemerteans studied. Ten arrangement described. Three primary ('palaeotype', 'heterotype', 'hoplotype') correspond to three supergroups (Palaeonemertea, Heteronemertea, Hoplonemertea)....
Ribbon worms (phylum Nemertea) have traditionally been described and classified based on a combination of internal external morphological characters.The extent, wealth details, these descriptions vary both over time amongst authors.In addition, definitions characters character states are in many cases vague, causing problems for identification phylogenetic analyses.Here, we suggest system describing nemerteans list their with the actual description form vector state symbols.We argue that...
North Pacific specimens of M elanochlamys sea slugs were examined morphologically (including the male reproductive morphology, shell and external coloration) sequenced for three genes (mitochondrial COI 16S nuclear H3). Phylogenetic species delimitation analyses used to determine evolutionary relationships diversity among examined. Both molecular morphological data revealed an unexpected high level cryptic diversity. At least four distinct occur on Northwestern Pacific. ezoensis occurs in...
The heteronemertean genus Lineus Sowerby, 1806 has been badly in need of revision because its apparent non-monophyly. In this paper, we focus on torquatus Coe, 1901, one the species that occur commonly waters around North Pacific, as well a few other allied distributed western including alborostratus Takakura, 1898 and Cerebratulus montgomeryi 1901. Based phylogenetic analyses using 16S, COI, 28S, 18S, H3 gene ITS sequences, detected well-supported clade comprised heteronemerteans with...
A higher-level classification of Nemertea has been updated based on insights from recent phylogenetic studies.According to this classification, the phylum includes two superclasses (Pronemertea and Neonemertea), three classes (Palaeonemertea, Pilidiophora, Hoplonemertea), eight orders.The order Arhynchonemertea is considered as an incertae sedis taxon.For all taxa above family level, diagnoses synapomorphies are provided.How site article:
