The specific epithet refers to the montane habitat of the species.


This species differs from other congeners by the epigynal plate being wider than long (vs. longer than wide in the remaining species) and the short septum (as long as receptacle length and as long as wide vs. a long septum that is longer than wide and longer than receptacle) (Figs 3d, e).


Female (holotype). Total length 10.95. Carapace 4.1 long, 1.65 wide. Eye sizes and interdistances: AME: 0.14, ALE: 0.20, PME: 0.21, PLE: 0.17, PME-PME: 0.05. Carapace, sternum, labium, chelicerae, and maxillae light brown without any distinct patterns, with scattered short setae and darkening in the ocular area. Chelicerae with one anterior tooth and bifurcated posterior keel. Abdomen light grey with short grey setae and scattered dark patches dorsally. Anterior lateral spinnerets dark brown, relatively short, 3.7 x longer than wide, spaced by less than two diameters of a single ALS, with long spigots of the piriform glands. Legs yellow. Leg measurements: I: 12.85 (3.55, 1.7, 2.7, 2.7, 2.2), II: 12 (3.2, 1.50, 2.55, 2.6, 2.15), III: 11.4 (3.05, 1.45, 2.25, 3.0, 1.65), IV: 14.9 (3.9, 1.55, 3.15, 4.1, 2.2).
