Amka River, mouth of Khetana Spring, Sphagnum hillocks in valley forest of Betula and Larix dahurica (leg. VZ). Description. Total length of male/female 1.68-1.78/1.78-1. 85. Carapace yellowishbrown; its length/width 0. 78-0. 80/0. 55-0. 58 in male, 0. 78-0. 80/0. 58-0. 63 in female; male carapace as in Fig. 47. Chelicerae with 4 promarginal teeth. Legs dark yellow; length of joints of legs I/IV 0. 55/0. 63+0. 18/0. 18+0. 48/0. 53+0. 40/0. 43+0. 35/0. 35 in male, 0. 63/ 0. 70 + 0. 20/0. 20+0. 50/0. 58+0. 43/0. 48+0. 35/0. 35 in female; tibial spines 2211, Id of joint in female, 1/4 d of joint on male; Tm IV - 0. 47, Tm IV absent. Abdomen dark grey. Genitalia of both male and female as in Figs 48-52. Comparison. By the shape of the male carapace, the new species seems closer to D. latifrons (O. Pickard-Cambridge, 1863), but is well distinguishable by the vertically elongated palpal tibia devoid of apophysis and practically rectangular lateral plates of the epigyne (cp. WIEHLE 1960). Distribution. Siberia: Putorana Plateau, Middle-Siberian Tableland, upper Kolyma River, northern and western coasts of Okhotsk Sea. Savignya basarukíni sp.n.

Carapace greyishbrown, its length/width 0.83-0.85/0. 60-0.63 in male, 0. 70-0.75/0. 50-0. 55 in female; male carapace as in Fig. 53. Chelicerae with 4 promarginal teeth. Legs brownish-yellow, length of joints of legs I/IV 0. 58/0. 65+0. 20/0. 20+0. 48/0. 58+0. 43/0. 45+0. 35/0. 35 in male, 0. 53/0. 58+0. 18/0. 18+0. 43/0. 53+0. 38/0. 43+0. 30/0. 30 in female; tibial spines 2211, 1 d of joint in female, 1/4 d of joint in male; Tm I - 0.43, Tm IV absent. Abdomen dark grey, almost black. Genitalia of both male and female as in Figs 54-59. Comparison. By the shape of the male carapace, the new species seems to be especially closely related to S. frontata Blackwall, 1833, but differs by the form of both embolic division and suprategulum (cp. WIEHLE 1960; TANASEVITCH 1985). By the epigyne S. basa- rukini sp. n. is related to S. birostrum (Chamberlin et Ivie, 1947), S. nenilini Marusik, 1988 and S. saitoi sp.n., but differs by the contiguous lateral plates of the epigyne (cp. MARUSIK 1988 and figs. 72-75). Distribution. Far East: Sakhalin Island and lower Amur River. Etymology. The new species I am glad to name after the collector of this material. Dr. Anatoliy M.

The record of this species in the Polar Urals by TANASEVITCH (1985) is erroneous (s. about S. nenilini MARUSIK 1988). Savignya borea sp.n.
