This genus is distinguished from Guhiceps by the shape of 

 the body, which is ovate and strongly compressed, by the 

 absence of teeth on the tongue and vomer in the young, by 

 the ventrals inserted below the pectorals, and by the coracoids, 

 which are not dilated and do not form an elongated symphysis ; 

 so that the thorax does not appear cultrate in this genus.
