Foretibia with 4 dorsal setae. Foretarsomeres slender, elongate. Midcoxa dark brown. Hind coxa yellowish-brown. Hind coxal lobe light brown, short, with ventral, dorsally curved, bare digitiform process. Posterior face of hind femur with peglike setae forming dorsal line and ventral group to short line; more distally with slight ventral bulge and distal sinuous carina ( Figs 105–106).
