Legs: P I —femur with 4 bands, tibia with 5 bands, third band small and incomplete; P II, P III —femora with 4 bands, tibiae with 4 bands. Ratio of bands, related tibiae and tarsomeres 1 follow table 50. Hypopygium yellow.

P II —apex of tibia 63 µm wide and with 2 apical pectinated spurs 45 and 55 µm long, spur ratio 0.72 and 0.50 respectively; tarsomeres 1–3 with 1 or 2 pseudospurs 44–55 µm long. P III —apex of tibia 65 µm wide and with 2 apical pectinated spurs 66 and 46 µm long, spurs ratio 0.47 and 0.57 respectively; tarsomeres 1–3 with 2 pseudospurs 62–74 µm long.
