Palp as in Fig. 17 View FIGURE 17 . Femoral apophysis weakly protruded, near middle part of femur. Tibia with large, round apophysis ventrally. Retrolateral tibial apophysis absent; prolateral tibial apophysis pronounced, round; dorsal tibial apophysis with wide base, tip curved, goose neck-shaped.Cymbium with an arc-shaped apophysis at retrolateral base.
