“…Thus, the diagnostic characters of G. complanata fit almost any varieties of the Siberian Glossiphonia , with the exception of G. concolor (Apathy, 1888) found in Lake Baikal (Kaygorodova & Pronin, 2013), and Glossiphonia sp. from Lake Gusinoe (Kaygorodova, Mandzyak, Petryaeva, & Pronin, 2014). Taxonomic uncertainty persists at the species level of the genus Glossiphonia , especially Palaearctic species, despite the efforts of previous researchers.…”

The study of biodiversity is a priority task of biological science. The structural unit of biodiversity is a species that has a clear identification in a taxonomic system. Morphological features are traditionally the main criteria for species discrimination in zoological studies. However, the presence of inter‐ and intraspecific polymorphism and phenotypic plasticity makes it difficult to identify species in many groups of invertebrates. To solve this problem, in this research, we analyzed morphological and genetic data in combination to delimit species among the Eastern Siberia Glossiphonia leeches using different approaches. Morphology analysis revealed phenetically distinct groups, suggesting the existence of at least two species in the region, G. verrucata, a rare Palaearctic species, and a potentially new species Glossiphonia sp. Moreover, sequence‐based species delimitation methods congruently supported eight distinct species groups (including two Siberian species) within the available molecular dataset of the Glossiphonia world fauna, using phylogenetic (ML and BI), coalescent (ABGD and GMYC) methods, and pairwise analysis of sequences. The detected p‐distances (modal value of 0.11) between these 8 groups and the level of genetic polymorphism (max. 0.0041) within groups indicate that the groups are 8 independent species according to the DNA barcoding. Our results once again proved the usefulness of molecular systematics. At the same time, we detected several inaccuracies in the leech species identification, as well as many ambiguous sites in sequences uploaded on GenBank, which affects the analysis and impedes progress of DNA barcoding technology.

“…Other species, which occurs in Siberia and the Far East, was tentatively assigned to Alboglossiphonia cf. papillosa (Braun, 1805) based on a darker pigmentation of its dorsum 37 , 38 but it represents a separate North Asian species, which is described here.…”

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.

Most of these sequences were presented in published works (Apakupakul et al 1999;Oceguera-Figueroa et al 2010;Kaygorodova et al 2014;Saglam et al 2018;Bolotov et al 2019;Iwama et al 2019;Behrens-Chapuis et al 2021).…”

Helobdella stagnalis (Hirudinea: Glossiphoniidae), the first facultative mussel-associated leech in Europe

et al. 2022

The ecological group of mussel-associated freshwater leeches (Hirudinea) contains facultative and obligate inhabitants of the mantle cavity of freshwater mussels (Unionida) from Asia, Africa, North America, and South America. Here, we report on the record of a mussel-associated leech in Europe and present a list of its freshwater bivalve hosts. The widespread leech species Helobdella stagnalis (Glossiphoniidae) was recovered as a facultative inhabitant of the mantle cavity of the native Anodonta anatina, Unio pictorum, and U. tumidus, and the non-native Sinanodonta woodiana (Unionidae). Globally, the freshwater mussel-associated leech assemblage contains 17 species, including four Helobdella representatives: H. lineata and H. modesta in North America, H. adiastola in South America, and H. stagnalis in Europe.
