TmI 0.57 and TmIV 0.53. Opisthosoma 1.25 long, 0.76 wide, oval, pale, mid dorsally with pale broad band followed by three transverse cheveron posteriorly, ventral side pale.

Palp ( Figs 291A–D View FIGURE 291 , 292A, B View FIGURE 292 , 293A, B View FIGURE 293 ): Femur unmodified, almost longer than both patella and tibia. Patella shorter than tibia, ventrally grooved. Tibia one and half the length of cymbium, with one reterolateral and one dorsal trichobothria, reterolateral tibial apophysis (RTA) somewhat triangular with blunt tip, dorsal tibial apophysis (DTA), small, horn shaped with blunt tip; cymbium unmodified; paracymbium (PC) sclerotized, distal tip C-shaped; tegulum (T) sclerotized, with long transparent protegulum (PT) covering the embolus. Convector (CV) elliptical, transparent extending forward to form projection; embolus (E) filiform, running along the retrolateral margin of the convector, distal end curved, bifurcated, protruding above the apex of cymbium.
