| Summary: | 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, ... |
