A new species of stygobiontic interstitial annelid, Diurodrilus kunii sp. nov., is described based on material collected from medium sand sediment (ϕ = 1.2-1.7) at groundwater level (40-100 cm in depth; 5-15 m inland from splash zone) in the intertidal beach slope on Ishikari Beach, facing the Sea of Japan, Hokkaido, Japan. The new species differs from six known congeners in the arrangement of the anterior-head ventral ciliophores, the degree of development in the primary and secondary toes… 
Interstitial Annelida
TLDR
This article provides a review of the evolution, systematics, and diversity of these interstitial families, with the exception of Parergodrilidae, which was detailed in the review of Orbiniida by Meca, Zhadan, and Struck within this Special Issue.

Structural Studies on Diurodrilus Remane (Diurodrilidae fam.n.), with Description of Diurodrilus westheidei sp.n. from the Arctic Interstitial Meiobenthos, W. Greenland *
TLDR
The ultrastructure of D. subterraneus Remane, collected in the summer at Disko Island and Ystad, Sweden, is discussed with new information on the systematic status of this aberrant genus as indicated by the cuticle, pharyngeal area, ciliophores and the spermatozoa.
Trilobodrilus itoi sp. nov., with a Re-Description of T. nipponicus (Annelida: Dinophilidae) and a Molecular Phylogeny of the Genus
TLDR
Molecular phylogenetic trees based on concatenated sequences of the three genes showed that T. itoi and T. nipponicus form a clade, which was the sister group to aClade containing the two European congeners T. axi Westheide, 1967 and T .
Is Diurodrilus an annelid?
TLDR
On the basis of the configuration of the nervous system and the cuticle Diurodrilus is regarded to belong to Spiralia, possibly close to Annelida; however, until further evidence is acquired it should be regarded as incertae sedis in this large animal clade.
Evolution of interstitial Polychaeta (Annelida)
TLDR
Three new supplementary evolutionary hypotheses for these families are here suggested: basal position of Diurodrilidae in Polychaeta, evolution of Nerillidae in mud, and evolution from meio- to macrofaunal forms of Psammodrilidae.
Pattern of morphological diversification in the Leptocarabus ground beetles (Coleoptera: Carabidae) as deduced from mitochondrial ND5 gene and nuclear 28S rDNA sequences.
TLDR
One of the possible interpretations of the present results would be that morphological transformations independently took place in the different lineages, sometimes with accompanying parallel morphological evolution, resulting in the occurrence of the morphological species belonging to the same species group (= type) in theDifferent lineages.
Molecular phylogenetic analysis of three groups of Asian epilachnine ladybird beetles recognized by the female internal reproductive organs and modes of sperm transfer
TLDR
Partial sequences of the nuclear 28S ribosomal RNA gene and mitochondrial DNA NADH-dehydrogenase subunit 2 gene of 25 species of phytophagous ladybird beetles from Asia were determined and reconstructed the phylogenetic trees for each gene by the maximum parsimony and maximum likelihood methods.
First molecular evidence for the existence of a Tardigrada + Arthropoda clade.
TLDR
The results obtained represent the first molecular evidence for a Tardigrada + Arthropoda clade and indicate the need to review those obtained solely on morphological characters.
Molecular phylogenetics of cupped oysters based on partial 28S rRNA gene sequences.
TLDR
Molecular data from domains D1, D2, and partial D3 of the 28S rDNA supply sufficient phylogenetic information to determine systematic relationships among the extant oyster taxa, from the major species groups to the family level, thus providing valuable characters that are able to supplement the paucity of morphological characters so far recognized.
Soil-dwelling polychaetes: enigmatic as ever? Some hints on their phylogenetic relationships as suggested by a maximum parsimony analysis of 18S rRNA gene sequences
TLDR
Parergodrilus heideri and Stygocapitella subterranea Knollner, 1934 are interpreted as resulting from an ancient emergence and a rapid radiation of Polychaeta, and these polytomies are corroborated by independent evidence.
