Cercus and proctiger hairs shorter than epandrium hairs. Lobes of hypandrium vestigial but with long hairs ( Figs 16 & 18 ). Legs yellow apart from brown tips to hind femora ( Fig. 13). Dorsal hair palisade of mid tibia extends about 0.6 times its length. Hairs below basal half of hind femur longer than those of anteroventral row of outer half ( Fig. 19 ).
