“…Most prior molecular phylogenetic work on A. peledina has focused on COI and 18S sequence data. However, more recent studies, such as our prior study, have incorporated other loci, such as 12S, 16S, and 28S (Tessler et al, 2018a;Bolbat et al, 2019). In addition to the Sanger data, a mitochondrial genome (Bolbat et al, 2020), ultraconserved element (UCE) data (Phillips et al, 2019a,b), and a transcriptome (Iwama et al, 2020) have recently been sequenced.…”

“…However, the other studies have tended to use smaller datasets, have different foci, or are poorly supported or unresolved (Erseus & Kallersjo, 2004;Rousset et al, 2008;James & Davidson, 2012;Bolbat et al, 2019); see Table 1 of our prior work for more details (Tessler et al, 2018a).…”

“…It would be most useful to add samples from central and eastern Russia. Unfortunately, a 12S sequence for A. peledina in the Baikal region of Russia from a recent publication was not made publicly available (Bolbat et al, 2019).…”

Acanthobdellida gnaw into the sides of salmonid fishes in frigid Arctic lakes and rivers, latching on with fearsome facial hooks. Sister to leeches, they are an ancient lineage with two described species. Unfortunately, Acanthobdellida are rarely collected, leading to a paucity of literature despite their unique morphology. Populations range from Eurasia to Alaska (USA), but few specimens of Acanthobdella peledina are represented in molecular studies, and no molecular data exist for Paracanthobdella livanowi, making their taxonomic position difficult to assess. We use phylogenetics and morphology to determine whether allopatric populations of A. peledina are distinct species and assess the current classification scheme used for Acanthobdellida. We produce a new suborder, Acanthobdelliformes, to match the taxonomy within Hirudinea. Scanning electron micrographs indicate species-level differences in the anterior sucker and facial hooks; molecular phylogenetics mirrors this divergence between species. We assign both species to the family Acanthobdellidae and abandon the family Paracanthobdellidae. Alaskan and European A. peledina populations are morphologically similar, but appear phylogenetically divergent. Our data strongly suggest that members of the order Acanthobdellida diverged relatively recently in their ancient history, but based on genetic distance, this divergence appears to pre-date the most recent cycles of glaciation.
