I have not seen either of the two species in this genus, 

 and can therefore give only a free translation of the general 

 characters of the genus. It is, however, closely related to 

 Ereniotyhis.

* Since the generic type is not designated the case is governed by 

 the International Code, Art. 30, according to which preference should 

 be given to the best described, best figured, best known, most easily 

 obtained species or one of which a type can be obtained. Following 

 this recommendation I indicate O. curvinervis Cam. as generic type.
