Male. Measurements (in mm): Body length 1.30; carapace 0.70 length, 0.50 width; abdomen 1.00 length, 0.50 width. Leg measurements: I 2.73 (0.80, 0.40, 0.60, 0.61, 0.32), II 2.55 (0.70, 0.30, 0.60, 0.65, 0.30), III 2.35 (0.70, 0.30, 0.55, 0.55, 0.25), IV 3.17 (0.90, 0.50, 0.70, 0.65, 0.42). Leg formula: 4> 1> 2> 3.

Cephalothorax. Carapace yellow-grey; chelicerae yellow to brownish-yellow; sternum yellow; legs and abdomen light yellow. Sides of carapace with reticulate veins, dorsal area without hairs. Margin of carapace without distinct setae or denticle. Eyes six in two rows, rather large, nearly equally-sized, compactly arranged, ALE slightly separated, posterior eyes in slightly retrocurved row, touching each other (Fig. 8 A and, C). Base of fang with two plumose hairs on lateral sides (Fig. 8 D and E). Labium wider than long, endites with membranous tip (Fig. 8 B).

Legs. Leg I: femur with 2 rows of setae; patella without setae; tibia with 2 ventral setae, 2 dorsal setae and a dorsal trichobothrium; tarsus without setae. Leg II, III and IV similar to leg I.

Abdomen. Dorsal scutum oval-shaped, covering nearly entirely abdominal length. Lobes on anterolateral corners of petiolar tube distinct, ridges developed, but without forming a scutal cove; opercula large, oval-shaped.

Male palp. Cymbium separated from bulb, with two robust spurs. Bulb with numerous membranous outgrowths on terminal part (Fig. 9 A, B).

Female. As in male, except as noted. Tibiae with three trichobothria. Measurements (in mm): Body length 1.75-1.90; carapace 0.78-0.90 length, 0.65-0.70 width; abdomen 1.10-1.35 length, 0.45-0.60 width. Leg measurements: I 2.33 (0.60, 0.32, 0.50, 0.48, 0.43), II 4.48 (0.60, 0.30, 0.50, 0.50, 0.25), III 2.01 (0.55, 0.27, 0.50, 0.45, 0.24), IV 2.80 (0.80, 0.31, 0.65, 0.65, 0.39).
