Cosmopolitan or Cryptic Species? A Case Study of Capitella teleta (Annelida: Capitellidae)
TLDR
The morphology and mitochondrial COI gene sequences of Capitella specimens from two localities in Japan concluded that these characters vary intraspecifically, and COI data indicate that C. teleta actually occurs in both the NW Atlantic and NW Pacific.
Molecular Systematics of Tanaidacea (Crustacea: Peracarida) Based on 18S Sequence Data, with an Amendment of Suborder/Superfamily-Level Classification
TLDR
The molecular results strongly supported a monophyletic group composed of Neotanaidae, Tanaoidea, and ParatanaoideA, with the first two taxa forming a clade, which contradict three previously suggested hypotheses of relationships.
A novel transmission pathway: first report of a larval trematode in a tanaidacean crustacean
This study reports on the first trematode parasite observed in any species in the crustacean order Tanaidacea. Metacercariae occupying the body cavity of the host (Longiflagrum nasutus) were detected
Diverse pereopodal secretory systems implicated in thread production in an apseudomorph tanaidacean crustacean
TLDR
The inferred thread‐producing apparatus in P. tomiokaensis is very different from that in Tanaoidesa and Paratanaoidea, suggesting that kalliapseudids evolved thread production independently from the latter two groups.
Hexapleomera urashima sp. nov. (Crustacea: Tanaidacea), a tanaidid epibiotic on loggerhead sea turtles at Yakushima Island, Japan.
TLDR
Hexapleomera urashima showed two COI haplotypes differing by one substitution, but separated from representatives of four other genera by 32.2-48.4% K2P distance, indicating that COI is not useful for phylogeny reconstruction within Tanaididae.
Selfing in a malacostracan crustacean: why a tanaidacean but not decapods
TLDR
It is shown, through microscopy and breeding experiments, that the simultaneously hermaphroditic malacostracan Apseudes sp.
Two New Shallow-water Species of Agathotanais (Crustacea: Tanaidacea) from Japan
TLDR
Two shallow-water species of Agathotanais are described, A. misakiensis sp.
Phylogenetic Position of Arctotanais in the Suborder Tanaidomorpha (Peracarida: Tanaidacea)
TLDR
Molecular phylogenetic analyses strongly supported the placement of A. alascensis in Tanaoidea, and consequently the diagnoses for TanaOidea and Tanaidae were amended to include either presence or absence of the ischium on the pereiopods.
Description of a New Hamatipeda Species, with an 18S Molecular Phylogeny (Crustacea: Tanaidacea: Typhlotanaidae)
TLDR
A phylogenetic reconstruction based on the 18S sequences recovered a highly supported Typhlotanaidae clade containing H. kohtsukai and Typhlotanais mixtus, with Paranarthrura sp.
Opisa takafuminakanoi, a new species of Opisidae from Hokkaido, Japan (Crustacea: Amphipoda).
TLDR
During field survey of the marine benthic fauna of Hokkaido, Japan, one of the authors collected an undescribed species of Opisa from off the southeast of Akkeshi Bay using a sledge net, which is described and illustrated in detail.
