Hyogonia is known only from the type-species, which occurs in 

 Venezuela, Brazil, Peru, and Bolivia. It is closely related to Oncometopia 

 from which it differs in its reticulate-veined forewings, its lack of 

 dorsomedian granulations on the clypeus, its more produced male 

 pygofer and the distincdy striated posterior portion of the scutellum. 

 The head is more broadly produced than in Oncometopia, with the 

 anterior margin more broadly curved. Schroder (1959a;43) indicated 

 that he had seen the type of the type-species, but no lectotype was 

 found in any of the European collections visited by me. The present 

 interpretation of H. reticulata (Melichar) is based on a male specimen 

 determined by Melichar in HNHM which varied slightly from the 

 accompanying illustration in that the pygofer is shorter and the more 

 dorsal of the aedeagal processes are slighdy longer.
