Figs 74–78
Type material. Holotype ♁, CHINA: Sichuan Province: Aba Tibetan and Qiang Autonomous Prefecture, Mao County, Mountain Ecosystem Positioning Station (31°41.539´N, 103°53.809´E, 1885 m a.s.l.), 26 May 2015, leg. Luyu Wang.
Paratypes: 11 ♀, with same data as holotype.
Etymology. This specific name is derived from the type locality; noun in apposition.
Diagnosis. This new species resembles Punctus taibai sp. nov. in having a similarly shaped embolus, but can be recognized by: 1) the thin retroventral tibial apophysis, tapering from the base to the tip, with a smooth prolateral margin and bifurcated tip (vs retroventral tibial apophysis wide, with a triangular apophysis on the prolateral margin, and wide, not bifurcate tip, compare Fig. 76B–C with Fig. 71B–C), 2) the short dorsal tibial apophysis (vs long, compare Fig. 76E with Fig. 71C, E), 3) the arc-shaped tegular apophysis (vs blunt triangular-shaped, compare Fig. 76B with Fig. 71B), 4) copulatory openings concealed in anterior margins of concavities (vs directed mesally, towards each other, compare Fig. 77A with Fig. 72A), 5) the oval bursa (vs round, compare Fig. 77B with Fig. 72B).

Coloration. Carapace brown, oval, with several markings resembling flowing water droplets beside fovea and sparse iridescent scales in dorsal view. Abdomen darker in color than carapace, with large dorsal scutum covering nearly entire abdomen and sparse iridescent scales dorsally (Fig. 74A, B). Legs yellow to black; all tibia tips with nearly white annuli.
Palp as in Figs 76, 88A–D. Femoral apophysis protruding, with several setae, near tip of femur. Retroventral tibial apophysis wide, tapering from base to tip, tip bifurcated, short branch triangular; dorsal tibial apophysis short, strong, tapering from base to tip. Tegulum narrower than cymbium, oval; tegular apophysis small, arc-shaped. Sperm duct distinct, covering more than half length of tegulum, tapering from retrolateral side of tegulum to embolus. Embolus short, slanting posteriorly. Conductor thin, transparent.

Epigyne as in Figs 77, 78E–F. Epigynal plate sclerotized. Copulatory openings large, anterior margin sclerotized, towards posteriorly, located at middle of plate. Copulatory ducts and connecting tubes short. Bursa oval, at middle of plate. Spermathecae small, globular, close to each other. Fertilization ducts located at anterior margin of spermathecae.
Distribution. China (Sichuan Province).
