REMARKS. The species was mentioned from Tuva for the first time by Stebaev (1964).

The only know locality was near the mouth of the Chaa-Khol River (the left tributary of the

Ulug (or Upper Yenisei) River), 30 km W Shagonar City. There is an evident erratum in the original text (30 km E Shagonar City), because actually this river valley is to the west of

Shagonar City (and the Shagonar River). Unfortunately, this point has been inundated by the

Sayano-Shushenskoye Reservoir.

DISTRIBUTION. Tuva: UH (?). – S Siberia from the Altay Mts. and the vicinities of

Novosibirsk (Sergeev, 1991, 2007; Benediktov, 2006) to Tuva, the southern part of the Far

East, including S Kurile Islands, NE China, Korea, Japan. Probably the larvae of this species were recorded from W Siberia as Pteronemobius sp. by Bey-Bienko (1925).

ECOLOGY. According Stebaev (1964) the abundant population of this small cricket was observed in typical habitats: wet open plots of flood-plains with sand and stones between meadows and willows. The crickets actively sang during warm nights and cloudy days. No new populations of this small cricket were found in Tuva during last decades, despite some opportunities for the species to use anthropogenic habitats (in the southeastern part of W

Siberia, the species often occurs in wet habitats with gravel, especially along roads).
