We retain A. laticlavia as a species distinct from A. regia, because 

 the specimens at hand and the various published descriptions of the two 

 forms indicate that the Peje-rei of Chile has the head proportionately 

 smaller than the very similar fish from Peru (A. regia). It is not 

 improbable that the two will be found to intergrade. 



The records of laticlavia from southern Chile (Smitt), Falkland 

 Islands (Giinther), and Argentina (Berg, etc.) probably all refer to 

 other species of the genus.
