description: <i>Mongolicosa lizae</i> sp. n. Figs 8–9, 12–13, 46–53, 69–71, 75–76 <b>Types.</b> RUSSIA: <b>Tuva Republic</b>: holotype &amp;male; (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&amp;male; 3&amp;female; (ISEA, 001.8662), 1&amp;female; (ISEA, 001.8723), together with the holotype; 5&amp;male; 3&amp;female; (ZMMU), same locality, alpine meadow with scree, 2600–2700 m, 05.06.2017, A.A. Fomichev. <b>Etymology.</b> The specific name is a matronym in honor of my wife, Elizaveta A. Nepaeva (Barnaul, Russia), who helped in spider collection for this project. <b>Diagnosis.</b> <i>Mongolicosa lizae</i> <b>sp. n.</b> is most similar to <i>M. buryatica</i> in having a tegular apophysis (<i>Tg</i>) with arms equal in length to each other, a smoothly curved embolus (<i>Em</i>) without a basal spine, and lips of the epigyne (<i>Li</i>) the same height as septal base arms (<i>Sa</i>). The males of the new species can be distinguished from those of <i>M. buryatica</i> by an elongated terminal apophysis (<i>Ta</i>), which surpasses the embolus tip, and thinner basal part of the embolus (cf. Figs 46, 50 and fig. 187–188 in Marusik <i>et al.</i> 2004). The females can be distinguished from those of <i>M. buryatica</i> by having distinct apical pocket (<i>Ap</i>) composed by two separate hoods (cf. Fig. 69 and fig. 213 in Marusik <i>et al.</i> 2004). <b>Description.</b> 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 (<i>Aa</i>) sharply pointed and basal arm (<i>Ba</i>) rounded in ventral view. Palea (<i>Pl</i>) 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 (<i>Sd</i>) 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 (<i>Fo</i>) pear-shaped, as wide as long. Apical pocket deep. Septal stem (<i>Ss</i>) thickened posteriorly. Septal base (<i>Sb</i>) anchor-shaped, 3 times wider than high, posterior edge triangular. Lips of the epigyne closely spaced. Receptacles (<i>Re</i>) clavate, clearly delineated from copulatory ducts (<i>Cd</i>). Copulatory ducts as long as receptacles, smoothly curved. <b>Distribution.</b> Known only from the type locality in the Tannu-Ola Mountains (Figs 75–76).
