The legs are orange-brown; the femur is somewhat light, the remaining segments yellow. The distal half of the patella bears triangular marks. A smoke-colored band is recognizable in the proximal and distal parts of the tibia. Leg Spination: Femur I and II with 1.1 dorsal and 1 anterior spine. Femur III with 1.1 dorsal, 1.1 antero-dorsal, 1.1 postero-dorsal spine. Femur IV 1.1 dorsal, 1 posterior spine. Tibia I and II at the tip with 1 antero-ventral spine. Tibia III 1.1 ventral, in the basal half with 1 anterior (near the center), 1.1 antero-ventral, 2.2.2 ventral, 1.1 posterior, 1 postero-ventral spine. Tibia IV 2.2.2 ventral, 1.1 antero-ventral, 2.1.1 posterior spines. Metatarsus I and II with 2 antero-ventral (long) spines, with scopula. Metatarsus III and IV without scopula.
