– Antennomere IV more than 4 times as long as wide ............................................ 7

5 Longitudinal sulcus on pronotum smooth, well-defined; triangular tooth of mesofemora large, occupying almost half of femoral length, spines on mesotibiae more distant from apex .................................................................................................. 6

– Longitudinal sulcus on pronotum almost absent, rugose; triangular tooth of mesofemora smaller, located more basally, spines on mesotibiae closer to apex ........... ............................................................................................... braunsi (Wasmann)

6 Rostrum prominent, acute, head with rough reticulate structure on whole surface, mesofemora in male normally developed, with shallow groove from middle to apex ......................................................................................... majusculus (Péringuey)

– Rostrum roundly acute, head with rough reticulate structure only on base and evanescent on rostrum, mesofemora in male swollen, with large and deep groove from middle to apex ..................................................................... joncooteri sp. n.

7 Posterior part of elytra with high prominence bearing setae (trichomes) adjacent to abdominal prominences ...................................................... gibbiventris (Raffray)
