Metatarsus III with three prolateral spines. Femur III thickest. Scopulae and claw tufts absent on trasi of all palp and legs. Palpal claw with a single branched tooth; legs each with three tarsal claws, paired claws with two denticles. Leg formula: 4123. Measurements of palp and legs: palp 7.35 (2.80 + 1.25 + 1.75 + 1.55), leg I 8.30 (3.10 + 1.55 + 1.75 + 0.95 + 0.95), leg II 7.50 (2.50 + 1.25 + 1.75 + 1.05 + 0.95), leg III 7.35 (2.50 + 0.90 + 1.65 + 1.10 + 1.20), leg IV 9.70 (3.25 + 1.25 + 2.00 + 1.90 + 1.30).
