Fovea slightly behind posterior border of PLE, at a depression ( Fig. 1 View FIGURES 1–5 ). Anterior half of thoracic region at the same level of cephalic region, then with an abrupt decline, becoming almost vertical ( Fig. 2 View FIGURES 1–5 ), with a narrow marginal stripe of yellowish setae, interrupted in the middle.

Palpal femur with a series of seven dorsal spines. Dorsal tip of femur and dorsal patella with abundant yellow hairs. Palpal tibia with RTA and RvTA ( Fig. 7 View FIGURES 6–9 ); Bulb with long embolus ( Fig. 6 View FIGURES 6–9 ). Legs with internal bump on coxae, more prominent on I ( Fig. 4 View FIGURES 1–5 ). Trochanters also with ventral bump. Leg I robust. Patellae are narrow at their base and dilated in the middle. Leg III longer and more robust than IV. Tibiae III and IV distally dilated. Tarsi slightly dilated. Leg spination: femur I, II d1-1-1, p1di, III d1-1-1, p0-1-2, IV d1-1-1; patella I 0, II p1, III, IV r1; tibia I v2-2 -2, II v1 r-2-2, p1, III p1-1, r1-1, v1 rdi, IV p1, r1-1, v1 rdi; metatarsus I, II v2-2, III p1-2, r1-2, v1 r-1r, IV p1di, r1-2, v1 p-2.
