Two males, Durban, Natal, 1914 (W. Haygarth). 
The ventral aspect of the hypopygium was not described nor figured 
by Edwards (Plate XIII, figs. 46, 47). The pleurite has a swollen 
ventral lobe that is armed on the cephalic face with a sharp chitinized 
tooth. The ninth tergite (Plate XIII, fig. 46) is produced into a rather 
slender lobe that is squarely truncated at the apex, on each angle with 
a small papilla bearing a stout spine.
