Diagnosis: Oplognathus is distinguished from other Rutelinae and Areodina by the following combination of characters: (1) clypeal apex (ventral view) extending beyond apex of labrum (males and females) and weakly trilobed (males), (2) mesosternum not produced and forming a forward-projecting process, (3) male parameres asymmetrical (Jameson 1990; pers. obs. Jameson).


Distribution: Oplognathus occurs in Brazil from Bahia south to Sao Paulo.


Composition: The genus Oplognathus contains three species: O. bahianus Ohaus, 1912; O. helmreicheni Ohaus, 1914; O. kirbyi MacLeay, 1819.
