Diameters of eyes: AME 0.28, ALE 0.26, PME 0.26, PLE 0.27. Eye interdistances: AME–AME 0.15, AME–ALE 0.07, ALE–ALE 0.85, PME–PME 0.26, PME–PLE 0.31, PLE–PLE 1.30, ALE–PLE 0.09. OAW 1.58, CRW 2.15, OAW/CRW = 0.73. MOA 0.56 long, front width 0.70, back width 0.74. Clypeus height 0.30, 1.07 times AME diameter. Chelicerae with three promarginal and five retromarginal teeth.

Subtegulum with several staggered grooves on prolateral surface. Embolus shaped like bird’s head, longer than embolar apophysis, with digitiform, blunt tip; embolar apophysis short, flaky and truncated at tip, with file-like grooves on prolateral surface.
