Diagnosis. Psammostiba kamtschatica can be recognized by smooth posterior margin of male tergum 8, and by the distinct shape of the aedeagus ( Figs. 35 , H­K: Yosii & Sawada 1976) and spermatheca ( Fig. 26 : Brundin 1943)

Psammostiba kamtschatica differs from P. comparabilis and P. k e n a i i by lack of crenulation of the posterior margin of male tergum 8.

Distribution. Psammostiba kamtschatica is known from Russia (Kamchatka Peninsula, Kuril Islands) and northern Japan (Hokkaido).
