Mongolicosa lizae sp. n. Figs 8–9, 12–13, 46–53, 69–71, 75–76 Types. RUSSIA: Tuva Republic : holotype ♂ (ISEA, 001.8661), Eastern Tannu-Ola Mountains, watershed of Pravyi Shalash River and Choza River, 10 km NNE from Argalyg-Kozhagar Mt., 50°58’N, 92°26’E, mountain stony tundra and scree, 2700–2900 m, 05.06.2017, A.A. Fomichev; paratypes: 7♂ 3♀ (ISEA, 001.8662), 1♀ (ISEA, 001.8723), together with the holotype; 5♂ 3♀ (ZMMU), same locality, alpine meadow with scree, 2600–2700 m, 05.06.2017, A.A. Fomichev. Etymology. The specific name is a matronym in honor of my wife, Elizaveta A. Nepaeva (Barnaul, Russia), who helped in spider collection for this project. Diagnosis. Mongolicosa lizae sp. n. is most similar to M. buryatica in having a tegular apophysis ( Tg ) with arms equal in length to each other, a smoothly curved embolus ( Em ) without a basal spine, and lips of the epigyne ( Li ) the same height as septal base arms ( Sa ). The males of the new species can be distinguished from those of M. buryatica by an elongated terminal apophysis ( Ta ), which surpasses the embolus tip, and thinner basal part of the embolus (cf. Figs 46, 50 and fig. 187–188 in Marusik et al. 2004). The females can be distinguished from those of M. buryatica by having distinct apical pocket ( Ap ) composed by two separate hoods (cf. Fig. 69 and fig. 213 in Marusik et al. 2004). Description. Male (holotype). Total length 8.2. Carapace: 4.2 long, 3.25 wide. General appearance as in Fig. 8. Coloration. Carapace dark brown, almost black. Eye field black. Sternum dark gray. Labium and endites yellowgray. Chelicerae dark brown. Palps: Fe–Pt dark brown, Ti and cymbium black. Coxae yellow-gray with yellow spots. Legs dark brown dorsally, yellow-gray ventrally. Fe of all legs darker than others segments. Abdomen dark gray dorsally, almost black. Cardiac mark dark brown. Venter of the abdomen gray. Spinnerets black. Spination of leg I: Fe d1-1-1 p0-1-2 r1-1-1; Pa p1 r1; Ti d1-0-1 p1-0-0 r1-0-1 v2-2-2-1-2; Mt p0-1-0 r1-1-0 v2-2-0. Leg measurements: I 3.3, 1.6, 3.0, 3.1, 1.65 (12.65); II 3.3, 1.6, 2.85, 3.15, 1.6 (12.5); III 3.35, 1.55, 2.7, 3.7, 1.6 (12.9); IV 4.15, 1.7, 3.6, 5.55, 2.15 (17.15). Palp as in Figs 12–13, 46–53. Tibia and cymbium covered with dense black setae. Tegular apophysis with two arms, of which the apical arm ( Aa ) sharply pointed and basal arm ( Ba ) rounded in ventral view. Palea ( Pl ) without developed apophysis but with a small sclerotized part retrolaterally. Terminal apophysis long, thin, and slightly curved. Embolus relatively narrow, almost 3 times longer than wide. Embolic tip rounded. Sperm duct ( Sd ) runs closer to the inner (dorsal) margin of embolus. Female. Total length 8.8. Carapace: 4.4 long, 3.55 wide. General appearance as in Fig. 9. Coloration. Carapace dark brown. Sternum, labium and endites yellow-gray. Chelicerae brown. Coxae yellow-gray with yellow spots. Palps brown. Legs yellow-brown. Fe of all legs darker than other segments. Abdomen dark gray dorsally, almost black. Cardiac mark dark brown. Venter of the abdomen yellow-gray. Spinnerets black. Spination of leg I: Fe d1-1-1 p0-1-2 r1-1-1; Ti p1-0-0 r1-0-1 v2-2-2-1-2; Mt p0-1-0 r0-1-0 v2-2-0. Leg measurements: I 3.65, 1.8, 3.3, 3.05, 1.7 (13.5); II 3.7, 1.75, 3.1, 3.1, 1.7 (13.35); III 3.65, 1.65, 2.95, 3.8, 1.7 (13.75); IV 4.6, 1.8, 4.0, 6.0, 2.35 (18.75). Epigyne and internal genitalia as in Figs 69–71. Fovea ( Fo ) pear-shaped, as wide as long. Apical pocket deep. Septal stem ( Ss ) thickened posteriorly. Septal base ( Sb ) anchor-shaped, 3 times wider than high, posterior edge triangular. Lips of the epigyne closely spaced. Receptacles ( Re ) clavate, clearly delineated from copulatory ducts ( Cd ). Copulatory ducts as long as receptacles, smoothly curved. Distribution.
