Fovea nearly pit-shaped, dark and distinct. Clypeal height 0.08. Eye diameters: AME 0.07, ALE 0.10, PME 0.08, PLE 0.08. Eye interdistances: AME–AME 0.05, AME–ALE 0.05, PME–PME 0.10, PME–PLE 0.10; MOA 0.18 long, front width 0.13, back width 0.25. Chelicerae with three promarginal and two retromarginal teeth.

Two large atria anteriorly, nearly oval; two triangular impressions posteriorly implying the inner muscular attachment. Bursa situated medially of copulatory openings, teardropshaped; spermathecae globose, larger than bursa, situated in the posterior part of epigynum, connecting with the copulatory ducts through thinner and longer ducts; fertilization ducts short, arising from the posterolateral ends of the spermathecae.
