Remarks

The species was previously known only for the male holotype: ‘Khabarovsk Territory, Amur basin, Lyanchli River, confluent of Gorin River, 5.ix.1975, O.N. Kabakov leg.’ (ZIN). Based on the new material, I regard it as being widely distributed across the Russian Far East, except the southernmost territories.
