PANGONIA. 
The sucker is short and stout, hardly exceeding the length of the 
head ; the body is stout and square-shaped ; the stump on the angle of 
the tip cross-yein is rudimentary or none; the posterior submarginal 
areolet is closed in both sexes.

Tactna. 
Seems to connect Fidena with Pangonia: the mouth is more slender 
than that of Pangonia, and full twice the length of the head: the body is 
more slender and rounded: the stump on the angle of the tip cross-vein 
is rather long.
