This species is distinguished from F. clavitarsus , Boh, 
by the angulate character of the lateral lobes, which are 
devoid of spines. In clavitarsus the lateral lobes are armed 
with hooked spines. It is the female only that presents 
the clavate tarsi, and this fact misled me in describing 
planotarsus as a Mazarredia , the type being a male.

stature than the type form, but evidently belongs to this 
species.
