The complete mitochondrial genome of Alboglossiphonia lata (basionym: Glossiphonia lata ), sourced from a biodiversity hotspot of China, has been determined and reported in this study. It was 15,236 bp in length and consisted of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and three control regions. The mitogenome was deposited GenBank under the accession number PP165800. A. lata and other species within the Glossiphoniidae family were clustered together with high bootstrap values. The mitochondrial genome of A. lata provides valuable molecular data for further phylogenetic research on the Glossiphoniidae family.

“…Ironically, the Arctic Glossiphonia ‘ complanata ’ sensu earlier authors 13 – 16 , 22 , 25 includes several other species but does not contain G. complanata (Linnaeus, 1758) as such (see below). The taxonomic concept of several other taxa such as Hemiclepsis marginata (O. F. Müller, 1773) has also been shifted recently from a species having a nearly pan-continental distribution 2 , 10 , 15 to a composite taxon, which contains several species with more restricted ranges 56 , 57 .…”

“…Furthermore, we prepared a series of longitudinal slices of the body of several target (new to science) taxa. In particular, the leeches were processed using hematoxylin and eosin (H&E) stain 57 as described below. After fixation, the tissues were dehydrated through a graded alcohol series and embedded in paraffin.…”

The family Glossiphoniidae is a diverse and widespread clade of freshwater leeches, playing a significant role in functioning of aquatic ecosystems. The taxonomy and biogeography of leeches from temperate, subtropical, and tropical regions attracted much attention of zoologists, while their taxonomic richness and distribution in the Arctic are poorly understood. Here, we present an overview of the Eurasian Arctic Glossiphoniidae based on the most comprehensive occurrence and DNA sequence datasets sampled to date. This fauna contains 14 species, belonging to five genera and three subfamilies. One genus and five species are new to science and described here. The world’s northernmost occurrences of glossiphoniids are situated on the Taymyr Peninsula at 72° N, although further records at higher latitudes are expected. Most Arctic leeches are characterized by broad ranges crossing several climatic zones (e.g., Glossiphonia balcanica and G. nebulosa), although the distribution of two new species may be confined to the high-latitude areas. The Taymyr Peninsula with the nearby Putorana Plateau represents the most species-rich area (totally 9 species), while the European Arctic, Iceland, Kolyma Highland, and Chukotka Peninsula house depleted faunas (2–4 species per subregion). Finally, we show that the high-latitude melanism is a common phenomenon in glossiphoniid leeches.

“…To contribute to the understanding of mitogenomic evolution in annelids, and generate data for future taxonomic and phylogenetic studies, in this study, we sequenced and characterized the complete mitochondrial genome of a very recently discovered and described new leech species Hemiclepsis yangtzenensis Yang & Bolotov 2021 (Rhynchobdellida: Glossiphoniidae) (Xu et al. 2021 ). The specimen was collected from the skin of a Monopterus albus host in a fish breeding pond at the Aquatic Economic Animal Research Center of Yangtze University, 30.3590°N, 112.1376°E, Jingzhou, Hubei Province, China.…”

We present the complete mitochondrial genome sequence of a recently described new leech species named Hemiclepsis yangtzenensis Yang & Bolotov 2021 collected in central China. The mitochondrial genome is 14,984 bp in length and consists of 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes, all of which are encoded on a single strand. It exhibited a strong A + T bias of 72.87%. There is a large non-coding region (614 bp) located between the tRNA-Arg and tRNA-His genes, wherein we identified 40 short dispersed repeats, 13–22 bp long, 8 of which were direct, 20 inverted, and 12 palindromic. Phylogenetic analysis of 20 Hirudinea mitogenome sequences resolved monophyletic Glossiphoniidae, and H. yangtzenensis formed a sister lineage with Glossiphonia concolor.
