Leg chaetotaxy: I — femur d 1–1–1, pl 1, rl 1–1–1; patella pl 1, rl 1; tibia pl 1–1–1, rl 1–1, v 2–2–2a; metatarsus pl 1–1–1a, rl 1–1–1a, v 2–2–3a. II — femur  d 1–1–1, pl 1–1, rl 1–1–1; patella pl 1; tibia pl 1–1,  rl 1–1, v 2–2–2a; metatarsus pl 1–2a, rl 1–1–1a, v 2–2–2a. III — femur d 1–1–1, pl 1–1, rl 1–1–1; patella pl 1,  rl 1; tibia d 1–1, pl 1–1, rl 1–1, v 2–2–2a; metatarsus  d 1–1–1a, rl 1–1–1a, v 2–2–3a. IV — femur d 1–1–1, pl 1–1, rl 1;patella pl 1, rl 1; tibia d 1–1, pl 1–1, rl 1–1, v 2–2–2a; metatarsus pl 1–1–1a, rl 1–1–1a, v 1–2–2–3a. Palp — femur d 1–1–2, pl 1, rl 1; patella pl 1. Eye diameter and distances between the eyes: AM 0.30;  AL 0.26; PM 0.75; PL 0.60; AM–AM 0.09; AM– AL 0.08; PM–PM 0.30; PM–PL 0.60; AM–PM 0.15; AL–PL 1.26; AL–PM 0.18. Distances from eyes of the anterior row to the anterior clypeus margin: AM–clypeus 0.18; AL–clypeus 0.15. Anterior margin of chelicera groove with 3 denticles, posterior margin with 2 denticles.

Palp unusually large. Cymbium apically without spines but with hairs that are thicker than in other parts of cymbium. Maximum width of cymbium more than twice the width of its free portion. Bulbus with huge, dark, heavily chitinized tegular apophysis, bearing long ventral outgrowth. Owing to the outgrowth, tegular apophysis of bulbus longer than bulbus width. Dorsal surface of tegular apophysis with canal opening at its retrolateral margin, probably accommodating embolus during copulation. Embolus dark, chitinized, extending latero-apically from under the palea. Heavily chitinized synembolus, also extending from under the palea, lies above the embolus and probably serves for directing the embolus into the dorsal groove of  the tegular apophysis during copulation. Ends of embolus and synembolus resting in tegular depression. Retrolateral margin of tegular depression with membranous lobe.
