Hind femur armed with 7–8 spines on each side of ventral surface, hind tibia with 6–7 internal and 6-7 external spines on dorsal surface. 9 th abdominal tergite split into two spine-like lobes ( Fig. 28 View FIGURES 27–29 ); subgenital plate short, broader than long; styli almost as long as subgenital plate, cylindrical.
