 length of the tibiae. Median limbs similar to the cephalic but slightly 

 larger and more compressed. Caudal femora moderately robust, 

 length equal to that of the head, pronotum and tegmina, greatest width

 present on the external margin, no apical spine, eight spines present on 

 the internal margin including the apical spine; tarsi elongate, the joints 

 slender.
