Ribbon worm relationships: a phylogeny of the phylum Nemertea
TLDR
The most extensive phylogenetic analysis to date, to the authors' knowledge, of higher–level nemertean relationships, based on sequence data from four different genes is presented, finding that well–supported clades are, in general, compatible with earlier, more limited, analyses.

Open‐ocean barriers to dispersal: a test case with the Antarctic Polar Front and the ribbon worm Parborlasia corrugatus (Nemertea: Lineidae)
Open‐ocean environments provide few obvious barriers to the dispersal of marine organisms. Major currents and/or environmental gradients potentially impede gene flow. One system hypothesized to form…

Barcoding against a paradox? Combined molecular species delineations reveal multiple cryptic lineages in elusive meiofaunal sea slugs
TLDR
This study confirms extensive, morphologically cryptic diversity among meiofauna and accentuates the taxonomic deficit that characterizes meofauna research.

Disentangling ribbon worm relationships: multi‐locus analysis supports traditional classification of the phylum Nemertea
TLDR
The phylogenetic relationships of selected members of the phylum Nemertea are explored by means of six markers amplified from the genomic DNA of freshly collected specimens, acting as a scaffold to which one could pinpoint any previously published study.

Fundamental properties of the spiralian developmental program are displayed by the basal nemertean Carinoma tremaphoros (Palaeonemertea, Nemertea).

Mutation and Selection Cause Codon Usage and Bias in Mitochondrial Genomes of Ribbon Worms (Nemertea)
TLDR
It is proposed that codons containing A or U at third position are used preferentially in nemertean species, regardless of whether corresponding tRNAs are encoded in the mitochondrial DNA.

The Necessity of DNA Taxonomy to Reveal Cryptic Diversity and Spatial Distribution of Meiofauna, with a Focus on Nemertea
TLDR
Diversity of nemertean species is analyzed by considering the barcode region of the mitochondrial gene Cytochrome Oxidase subunit I (COI) and different species delineation approaches in order to infer evolutionarily significant units and results are consistent across different DNA taxonomy approaches.

Statistical Parsimony Networks and Species Assemblages in Cephalotrichid Nemerteans (Nemertea)
TLDR
Statistical parsimony network analysis provides a rapid and useful tool for detecting possible undescribed/cryptic species among cephalotrichid nemerteans based on COI gene and should be combined with phylogenetic analysis to get indications of false positive results.
