Type species: Zefevazia rosascostai Martínez, 1954 by original designation.

  ......
  Gender: feminine.
   

 

Diagnosis. The following characters will separate Zefevazia from all other South American Bolboceratini: head in the males with only one horn; females without horns, only with a tubercle situated near of the frontoclypeal region or in the frons and with an elevated ridge basal to clypeal apex. Antennal club semicircular. Pronotum in males with paired anteromedian excavations on either side of midline, dorsally with basal transverse ridge parallel to basal margin; females with a small concavity or depression located immediately behind of the apical margin of the pronotum. Scutellum triangular. Elytron with basal margin, with 7 striae between medial suture and humeral swelling. Prosternal process greatly reduced or absent. Mesocoxae distinctly separated. Metasternum pyriform, bulbous, with long, median metasternal carina; metasternal process wide, convex between mesocoxae. Protibial spur not extending to apex of protibia. Mesotibia and metatibia of variable shape in lateral view, with lobed transverse carina located subapically. Male genitalia: aedeagus subcylindrical, parallel-sided; parameres short, subrectangular, basally not membranous, with apex wide distally, truncate.

Remark. The elevation of Zefevazia to the generic level creates the following new combinations: Zefevazia cantisanii (Martínez), Zefevazia peruana (Boucomont), and Zefevazia quinquedentata (Felsche).  The species Zefevazia rosascostai Martínez is a revised combination.
