Palp: the tibia is a little shorter than the patella; the paracymbium is short, bluntly pointed at its apex and has a chitinized knob near the distal end; the conductor and embolus are finely attenuated at their tips (Figs. 92-94). One of the most distinctive features in this species is the complete absence of spines from the legs. The hair is coarse, however, and there are many bristles. Female hypotype.
