The salivary transcriptome of Limnobdella mexicana (Annelida: Clitellata: Praobdellidae) and orthology determination of major leech anticoagulants

TLDR
The phylogenetic analyses suggest that the ancestral leech was able to inhibit factor Xa and that some hirudins that have been reported in previous studies on leech anticoagulants may not be orthologous with the archetypal hirUDin.

Phylogenomic Analysis of a Putative Missing Link Sparks Reinterpretation of Leech Evolution

TLDR
The phylogenomic resolution of early-diverging leeches provides a useful framework for illuminating the evolution of key adaptations and host–symbiont associations that have allowed leeches to colonize a wide diversity of habitats worldwide.

An integrative taxonomic study of the genus Theromyzon (Hirudinea: Glossiphoniidae), with description of a new North American species

TLDR
This study sheds light on the discriminatory power of select morphological characters and the distribution of phenotypes within the genus Theromyzon, and provides a comprehensive classification framework for the known species inside the genus designed to facilitate identification and minimise future taxonomic confusion.

Unrecognized diversity of Trocheta species (Hirudinea: Erpobdellidae): resolving a century-old taxonomic problem in Crimean leeches

TLDR
A new species from the Crimean Peninsula is described based on a phylogenetic analysis of cox1 gene sequences and a reassessment of morphological characters such as colouration, annulation, size and arrangement of papillae, and genital anatomy and suggests close relationships of T. blanchardi sp.

Mitogenome of a stink worm (Annelida: Travisiidae) includes degenerate group II intron that is also found in five congeneric species

TLDR
This study determined the first mitogenome from the family Travisiidae (Travisia sanrikuensis), analyzed its mitogenomic features, and reconstructed a phylogeny of Sedentaria.

A new deep-sea fish leech of the bipolar genus Pterobdellina stat. rev. (Hirudinea: Piscicolidae) parasitic on the Antarctic toothfish Dissostichus mawsoni (Perciformes: Nototheniidae)

TLDR
The molecular phylogenetic analysis based on mitochondrial cox1, nad1 and tRNA Leu genes revealed sister relationships of P. vernadskyi sp.

A new species of Orobdella (Hirudinida: Arhynchobdellida: Orobdellidae) from Primorye Territory, Russian Far East

TLDR
Phylogenetic analyses showed that O. ghilarovi forms a fully supported clade with a monophyletic lineage comprising two species, O. kawakatsuorum and O. koikei, inhabiting Hokkaido, Japan.

Comparative Transcriptomic Analyses of Three Species of Placobdella (Rhynchobdellida: Glossiphoniidae) Confirms a Single Origin of Blood Feeding in Leeches

TLDR
Results show that an ortholog of the archetypal, single-copy, anticoagulant hirudin is present in at least 2 of 3 species examined, corroborating the notion of a single origin of blood feeding in the ancestral leech.

New data about the functional morphology of the chaetiferous leech‐like annelids Acanthobdella peledina (Grube, 1851) and Paracanthobdella livanowi (Epshtein, 1966) (Clitellata, Acanthobdellida)

TLDR
The digestive and the reproductive systems of leech‐like annelids were analyzed for the first time in such a high number of specimens and support the taxonomic division of the order Acanthobdellida into the families AcanthOBdellidae and ParacanthobDellidae.

Lumbriculids, branchiobdellidans and leeches: an overview of recent progress in phylogenetic research on clitellates

TLDR
A preliminary manually drawn cladogram based on re-evaluated characters supports Lumbriculidae, Branchiobdellida, Acanthobdella and Euhirudinea as a monophyletic taxon and before any nomenclatural changes are proposed, a resolution of the apparently paraphyletic Oligochaeta is necessary.

Morphological reinvestigation and phylogenetic relationship of Acanthobdella peledina (Annelida, Clitellata)

TLDR
The main emphasis is laid on the evaluation of the position of the taxon within the Clitellata, including a discussion of the Branchiobdellida, and the cladograms presented show the Acanthobdella peledina to be the sister group of the Euhirudinea.

18S rDNA phylogeny of Clitellata (Annelida)

TLDR
The analysis supports an earlier hypothesis based on morphological features that Capilloventridae represents a basal clade of Clitellata; in the 18S tree it shows a sister‐group relationship to all other clitellates.

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.

Validating Livanow: molecular data agree that leeches, Branchiobdellidans, and Acanthobdella peledina form a monophyletic group of oligochaetes.

TLDR
Results provide support for the hypotheses that leeches and branchiobdellidans are sister groups, that acanthobdella peledina are sister to them, and that together with the family Lumbriculidae they all constitute a clade within Oligochaeta.
