spines, the three proximal pairs the largest, the apical pair minute. 

 Caudal femora unarmed on the inferior keels; caudal tibiae with 

 23-26 external and 26-28 internal black teeth on the dorsal keels, with 

 the apical pair the largest ; central keels unarmed. Cerci bifurcate, 

 with a long, incurved outer arm and a much shorter straight internal 

 basal prong. Subgenital plate small, triangular, with a minutely 

 notched apex and two closely placed apical styli.
