“…Later, the Northeast Asian populations of what was thought to be Hemiclepsis marginata (O. F. Müller, 1774) sensu lato [1,2] were reconsidered as belonging to several separate species such as H. schrencki Bolotov et al, 2019 and H. tumniniana Bolotov et al, 2019 [19,59]. The former Holarctic taxa Helobdella stagnalis (Linnaeus, 1758) and Alboglossiphonia heteroclita (Linnaeus, 1761) [1,2] were also subdivided into several species with narrower ranges [8,29]. A similar biogeographic pattern was recovered in the fish leech Piscicola geometra (Linnaeus, 1758) (Piscicolidae), which was thought to have a Holarctic range [60].…”

Freshwater leeches belonging to the genus Glossiphonia Johnson, 1816 are fairly common benthic annelids in freshwater ecosystems throughout Eurasia, but the taxonomy of this group remains poorly resolved, and the species content of some local faunas is unsatisfactorily known. For example, it was thought that the only widespread species, Glossiphonia complanata (Linnaeus, 1758), dwells in Northeast Asia. Here, we revise the Northeast Asian Glossiphonia leeches with an integrative taxonomic approach. This revision is based on the largest DNA-sequence and morphological datasets collected to date. Two Glossiphonia species are recorded from the region. First, Glossiphonia koreaensissp. nov., a putative regional endemic species, was discovered in South Korea. Second, a valid name and complete description are provided for Glossiphonia mollissima Moore, 1898 (non-Grube, 1871). The latter name was wrongly applied through misidentification and, according to ICZN (Article 49), is unavailable. Hence, we propose a new name, Glossiphonia mooreisp. nov., in memory of Dr. J. Percy Moore, who discovered this leech. It is a prospective trans-Beringian species, ranging through Eastern Siberia, the Russian Far East, and Alaska (although Alaskan records are based on nonsequenced samples), showing a significant proportion of melanic individuals in samples north of the Arctic Circle. The latter pattern may reflect substrate-induced cryptic coloration (camouflage), but this hypothesis needs to be statistically checked in the future. Finally, a complete checklist of Glossiphonia species is presented.

The fish leech Acipenserobdella volgensis (Hirudinea: Piscicolidae) is a rare and poorly known freshwater species, which is thought to be an obligate parasite of sturgeons. This leech has a disjunctive range in Europe and eastern Siberia. Here, we estimate the phylogenetic affinities and host range of A. volgensis using a set of DNA sequences (COI and 18S rRNA gene fragments), field observation data, and a review of the body of literature. Based on a time-calibrated Bayesian phylogeny, we show that the European and Siberian lineages of A. volgensis have been separated since the latest Pliocene (mean age = 2.7 Ma). The analysis of available host records indicates that this leech is characterized by a broader host range as it was collected from fish belonging to four families (Acipenseridae, Cyprinidae, Salmonidae, and Esocidae). Conversely, only a few suitable primary hosts (six sturgeons, one cyprinid, and one salmonid fish) were confirmed by earlier research. Moreover, this leech could be considered a facultative mussel-associated species that uses bivalves (duck mussel Anodonta anatina; Unionidae) as shelter. Globally, three other piscicolid leeches have been recorded from the mantle cavity of bivalve molluscs, that is, the freshwater taxa Caspiobdella fadejewi and Alexandrobdella makhrovi, and the marine species Austrobdella coliumicus.
