Palpal tibia with two unciform frontal apophyses S. producta Holm Carapace with two subsequently disposed cephalic elevations carrying AME and PME, respectively. Posterior cephalic elevation more or less vertical. Anterior cephalic elevation in lateral view almost as long as posterior one S. borea sp. n. Anterior cephalic elevation in lateral view almost twice as long as posterior one S. yasudai (H. Saito) Posterior cephalic elevation extended more or less horizontally anteriad. PME situated in distal third of posterior cephalic elevation S. zero sp. n. PME situated in middle part of posterior cephalic elevation. Posterior cephalic elevation thick, its apex in lateral view equal to 4-5 diameters of AME, with a distinct constriction in distal half. Constriction of posterior cephalic elevation almost half as deep as latter's own diameter; carapace 1.00-1.10 mm long „ .. , . . . r * S. birostrum (Chamb. et Iv.)

Posterior cephalic elevation directed strictly horizontally, its apex reaching to that of anterior cephalic elevation _ Savignya s p. Posterior cephalic elevation directed obliquely ventrad at an angle of ca. 25°, its apex not reaching to that of anterior cephalic elevation Females *. Carapace 0. 82-0. 93 mm long. Lateral plates of epigyne separated in their posterior parts by a distance over a width of each of them S. producta Holm Lateral plates of epigyne closer to each other, in their posterior parts almost contiguous S. borea sp. n. Carapace 0. 50-0. 80 mm long. Inner corners of epigynal lateral plates broadly rounded S. ussurica sp. n. Inner corners of epigynal lateral plates rectangular.
