Type material.
Holotype ♂ (TRU-XZ-ANY-0001), China: Xizang Autonomous Region, Linzhi City, Chayu County, Cibagou National Nature Reserve (28°36.03′N, 97°4.01′E, ca 2200 m), 14 Aug. 2023, C. Wang and H. Yao leg. Paratypes 1♀ (TRU-XZ-ANY-0002), same data as for holotype; 1♀ (TRU-XZ-ANY-0003), Cibagou National Nature Reserve (28°41.43′N, 97°2.86′E, ca 2570 m), 25 Jun. 2023, C. Wang leg.
Etymology.
The specific name is a noun in apposition and refers to the type of locality, Cibagou National Nature Reserve.
Diagnosis.
The species is closely similar to that of A. linzhi sp. nov., in habitus and copulatory organs, but it can be easily distinguished by the following: 1) the main portion of the median apophysis is almost oval, and slightly longer than wide in ventral view (Fig. 2B View Figure 2 ), vs elongate-oval, more than two times longer than wide in A. linzhi sp. nov. (Fig. 3B View Figure 3 ); 2) the conductor is acutely narrowed distally (Fig. 4A View Figure 4 ), vs almost tapered at distal half in A. linzhi sp. nov. (Fig. 4B View Figure 4 ); 3) the atrium is wider than long, and the median septum has a pair of laterally extended lamellar processes (Fig. 2D View Figure 2 ), vs atrium is longer than wide, and the median septum lacks similar processes in A. linzhi sp. nov. (Fig. 3D View Figure 3 ); 4) the accessory glands are located terminally on copulatory ducts (Fig. 2E View Figure 2 ), vs located medially in A. linzhi sp. nov. (Fig. 3E View Figure 3 ); and 5) the spermathecae are elongate-oval (Fig. 2E View Figure 2 ), vs almost spherical in A. linzhi sp. nov. (Fig. 3E View Figure 3 ). The male also somewhat resembles that of A. tibet Lin & Li, 2021 in having similar palp, especially the invert L-shaped conductor in retrolateral view, but it can be easily distinguished by the retrolateral tibial apophysis, which has a dorsal ramus about one-fifth the ventral ramus length and with a blunt end in retrolateral view (Fig. 2C View Figure 2 ), vs the dorsal ramus more than half the ventral ramus length and with a somewhat pointed tip in A. tibet ( Lin et al. 2021: fig. 7C), and by the smooth conductor (Figs 2C View Figure 2 , 4A View Figure 4 ), vs serrated on the inner margin in A. tibet ( Lin et al. 2021: fig. 13B).
Description.
Male (holotype; Figs 1A, B View Figure 1 , 2A-C View Figure 2 , 4A View Figure 4 ). Total length 6.72. Carapace 3.20 long, 2.78 wide. Abdomen 3.53 long, 2.35 wide. Clypeus 0.15 high. Eye sizes: AME 0.12, ALE 0.15, PME 0.17, PLE 0.18. Legs: I 9.84 (2.24, 0.79, 3.06, 2.49, 1.26), II 8.48 (2.39, 0.75, 2.66, 1.90, 0.78), III 5.99 (1.95, 0.65, 1.62, 1.26, 0.51), IV 8.67 (2.46, 0.64, 2.34, 2.41, 0.82). Carapace pale yellow to brown, with sub-oval thorax, slightly elevated cephalon, and big, irregular, brown markings; fovea longitudinal, dark red. Chelicerae red-brown, with four promarginal and seven retromarginal teeth. Endites yellow, longer than wide, bearing dense dark setae on inner portion of anterior margins. Labium darker than endites, bearing dark setae at distal margin. Sternum yellow to red-brown, covered with dense short setae, and with three pairs of anteromedian yellow spots laterally. Legs yellow to red-brown, with triangular ventral apophyses on base of coxae. Abdomen elongate-oval, dorsum red-brown to dark brown, spotted, with longitudinal, anterior pale band, irregular, median, dark patch, and two pairs of medium muscle depressions; venter pale to red-brown.
Palp (Figs 2A-C View Figure 2 , 4A View Figure 4 ): patella slightly longer than wide, with short, sclerotized distro-prolateral apophysis less than one-tenth its length; tibia about 1.5 times longer than wide, with half-round, base-ventral apophysis and bifurcated retrolateral apophysis, which has long, bar-shaped ventral ramus directed towards ca 11:30 o’clock position apically in retrolateral view, and short, lamellar dorsal ramus; cymbium setose, bearing two distro-prolateral macro-setose; bulb almost oval; tegulum swollen; subtegulum elongated, prolaterally located; median apophysis originates from the medium of retrolateral side of bulb, the main portion almost oval, and with rather pointed tip slightly curved dorsally; embolus thin, weakly sclerotized, partly hidden by conductor in ventral view; conductor anterior to the base of median apophysis, curved into invert L-shape in retrolateral view.
Female (TRU-XZ-ANY-0002; Figs 1C View Figure 1 , 2D-F View Figure 2 ). Total length 8.32. Carapace 3.05 long, 2.36 wide. Abdomen 5.59 long, 3.54 wide. Clypeus 0.17 high. Eye sizes: AME 0.11, ALE 0.15, PME 0.16, PLE 0.17. Measurements of legs: I 11.15 (3.03, 1.09, 3.20, 2.48, 1.35), II 9.78 (2.75, 0.93, 2.76, 2.17, 1.17), III 7.56 (2.28, 0.88, 1.74, 1.79, 0.87), IV 10.49 (3.04, 0.92, 2.51, 2.92, 1.10). Habitus (Fig. 1C View Figure 1 ) similar to that of male except having broad, longitudinal, pale band extending across the whole surface, only with sex retromarginal cheliceral teeth and lacking ventral apophysis on the base of coaxe.
Epigyne-vulva (Fig. 2D-F View Figure 2 ): wider than long, with anteriorly located, oval atrium more than half the epigynal width; median septum medially located on atrium, with strongly sclerotized, laterally extended lamellar processes; copulatory openings invisible; copulatory ducts strongly curved at base and then gradually thickened to connected to the anterolateral portions of elongate-oval, touched spermathecae, with short, terminal accessory glands; fertilization ducts lamellar, originate from the inner-base of spermathecae.
