 Type : Uaru amphiacanthoides Heckel. 



This genus is readily distinguished from related genera by the 

 enlarged scales in the lateral line. In this respect it resembles those 

 species of Crenicichla having a large number of scales, but differs 

 from them widely in shape, dentition, and preopercular margin.
