Description. Male. Total length 2. 18. Carapace 1.00 long, 0.75 wide, pale brown, with a darker margin. Chelicerae 0.58 long. Legs pale brown. Chaetotaxy: Fel: 0-1-0-0; Til, III, IV: 2-1-1-0, II: 2-0-1-0; Mtl-IV: 1-0-0-0. Tml - 0. 22. Leg I - 4. 07 long (1.05+ 0.30 + 1.03 + 0. 98 + 0. 71), IV - 3. 98 long (1. 05 + 0. 28 + 1. 00 + 1. 00 + 0. 65). Palp (Figs. 10-13): Patella with a large spine surmounting a conical knob. Tibia with a thick curved dorsal spine directed forward. Paracymbium toothless. Lamella characteristica distally split into two narrow, sharp, subequal rami. Abdomen 1. 18 long, 0.80 wide, pale grey. Female. Total length 2.21. Carapace 0. 98 long, 0. 78 wide. Chelicerae 0. 50 long. Tml -0.21 (another specimen - 0.21). Leg I - 3. 90 long (1. 00 + 0. 30 + 1. 00 + 0.90 + 0. 70), IV - 3. 64 long (1.03 + 0. 28 + 0. 83 + 0. 90 + 0. 60). Abdomen 1. 25 long, 0. 80 wide. Epigyne as in Figs 14-15. Body and leg coloration, chaetotaxy as in male. Diagnosis: The new species is especially close to the Siberian L. karpinskii (O. Pickard-Cambridge, 1873), but differs . from it by the shape of the spines on the male palpal tibia, more bifid lamella characteristica, shorter and broader scape of the epigyne, and presence of a dorsal spine on the metatarsus IV.

Carapace 0.98 long, 0.78 wide, pale brown, with vague grey short radial stripes and a darker margin. Chelicerae 0. 48 long. Legs pale brown. Chaetotaxy: Fel: 0-1-0-0; Til: 2-1-1-0, 11:2-0-1-0, III-IV : 2-0-0-0; Mtl-IV: 1-0-0-0. Tml - 0. 19. Leg I - 3.71 long (0. 98 + 0. 25 + 0. 93 + 0. 90 + 0. 65), IV - 3. 75 long (1. 00 + 0.25 + 0.95 + 0.95 + 0. 60). Palp (Figs 16-18): Patella as a dorsally elongated cone carrying a large curved spine. Tibia with a stout spine surmounting a knob and a small sharp tooth in front of it. Cymbium in the middle with a small comb-shaped outgrowth and a very small sharp tooth. Lamella characteristica well sclerotized, dark, terminally serrate. Abdomen 1. 15 long, 0.63 wide, grey. Female. Total length 2.25. Carapace 0.80 long, 0. 65 wide. Chelicerae 0.40 long. Tml - 0. 22 (in the series 0. 20-0. 21). Leg I - 3.18 long (0. 83 + 0. 25 + 0. 80 + 0.75 + 0. 55), IV - 3. 19 long (0. 88 + 0, 23 + 0. 80 + 0. 75 + 0. 53). Abdomen 1. 00 long, 0. 70 wide. Epigyne as in Figs 19-20. Body and leg coloration, chaetotaxy as in male. Diagnosis: The new species has a peculiar structure of the male palpal tibia, a conspicuous shape of both paracymbium and lamella characteristica. By the genital structure it resembles both L. ussuricus sp. n. and L. karpinskii (O. Pickard-Cambridge, 1873) (s. TANASEVITCH 1986), particularly in the female sex: the epigyne of both latter species has a long, slender scape and well-developed lateral walls, though only in L. karpinskii the base of the scape is covered with the anterior wall of the epigyne.
