Euglesa hinzi (Kuiper, 1975) View in CoL ( Fig. 9F View Figure 9 )

Pisidium hinzi Kuiper, 1975 : text 27–31, figs 1–6, 28, 30.

Type series: Holotype: SMF No. 192849, and 10 paratypes ZIN, nos 1, 2 in the systematic catalogue.

Type locality: Norway, ‘ Buetjörni (=Davggeluobal), 147 m NN, Flachsee (tiefste Stelle 9 m), Varangerhalbiusel im NO Norwegens’ .

Material examined: Russia: Yakutia , Ust-Kuiga , Yana River Basin , VIII.2019, Zubrii leg., one specimen (lot no. RMBH MSph-572- 2); Gydan Peninsula VII.2017, Sokolova & Shevchenko leg., 25 specimens (lot nos RMBH MSph-361, MSph-366, MSph-374), VashutkinylakesVIII.2016, Aksenova, Aksenov, Bespaliy, Sokolova & Shevchenko leg., one specimen (lot no. RMBH, MSph-161) .

Description: The mean shell length ± SD is 2.4 ± 0.2 mm (N = 15), shell is rounded in shape ( Fig. 9F View Figure 9 ). The beaks are rounded, slightly prominent, offset to the posterior edge of the valves ( Fig. 10A View Figure 10 ). The cardinal tooth of the right valve is curved, with a branched posterior end. The cardinal teeth of the left valve are slightly curved, almost parallel to each other ( Fig. 10A View Figure 10 ).

Distribution: Northern Europe and Siberia.

Comments: We analysed the original descriptions and type specimens of some nominal species described from Eurasian localities where our speciments were found or from closely situated localities: Euglesa jacutica (Starobogatov & Streletzkaja, 1967) , Euglesa jamalensis Dolgin & Starobogatov, 1973 , Euglesa johanseni Dolgin & Korniushin, 1994 , Euglesa hinzi Kuiper, 1975 , and Euglesa obensis Starobogatov, Anistratenko & Dolgin, 1990 (Supporting Information, Fig. S1 View Figure 1 ). The molecular genetic data (16S rRNA sequences) obtained have no analogues in GenBank, with Euglesa parvula (Clessin in Westerlund, 1873) being the closest ally. Morphologically, nominal species in this group have similar conchological features with the E. hinzi group, i.e. the section Hinziana Dolgin & Korniushin, 1993 ( Korniushin 1996). Thus, according to morphological features and molecular-genetic analysis, this species shoud be classified as E. hinzi ( Fig. 9F View Figure 9 ). The species status of E. jacutica , E. jamalensis , E. johanseni , and E. obensis needs to be clarified and cannot be solved here, since molecular studies of the topotypes of these species are necessary.
