Geographic distribution.

Palaearctic region. Previously mentioned as Holarctic species. However, recent molecular studies confuted its findings in North America ( Williams et al. 2013; Kaygorodova et al. 2019). In tundra zone of Russia: some lakes in the Korotaikha River basin ( Zaloznyj 1978), the Yamal Peninsula ( Stepanov 2016, 2017).

Location.

Small nameless lakes near Syattey-ty (67°33'46.2"N, 62°41'32.8"E; 67°33'11.6"N, 62°46'5.4"E; 67°33'13.6"N, 62°42'50.8"E; 67°32'27.9"N, 62°43'40.9"E); Lake D1 (67°36'2.2"N, 62°54'8.2"E; 67°35'52.8"N, 62°53'52.6"E).

This eurytopic species is numerically dominant in stagnant waters. Samples were collected from the shore; leeches were found in a free-living state on aquatic vegetation or on the underside of stones.
