Dr. Melicliar thus differentiates this genus. "Tibife compressed 

 and moderately widened. Differs from Oxyrhacliis by the absence 

 of the lateral processes to the jH-onotum, while the posterior 

 process is broad at base, narrowed like an awl behind and 

 straight. In this respect the genus comes near Garr/ara, while 

 in OA')jrh(cMs the hinder portion of the posterior projection is 

 strongly laterally compressed with the apex directed either up or 

 down."
