Male (holotype). BL 5.96, CL 2.90 (2.73–2.90), CW 2.00, CapW 1.10, EGW 0.82, LL 0.39, LW 0.41, SL 1.39, SW 1.29. Legs: 1243 (I: 17.00; II: 14.25; III: 11.83; IV: 14.00); ratio tibia I length:CW = 1:0.37. Male Palp: ( Fig. 11a,b View Fig ). Deeply bifurcate RTA with large, thin, widely divergent and dissimilar processes, (ventral processlong, tapering; dorsal process shorter, plate-like). RVTA with a small, acute retroapical ridge.
