Fig. 3

Flint 1963: 475.

This species is similar to P. cristula , n. sp., and P. rota Mosely 1937 in the possession of horn­like processes or “ cornuti ” projecting from the phallicata. Protoptila bicornuta differs from either of those species in that the ventral margin of sternum VIII is shorter and less deeply bifurcate apically, and the ventral processes of the phallicata are much shorter.
