Although I have not seen specimens of this species from either Ecuador or Peru, 

 I very much doubt whether they are subspecifically the same, for the reason that 

 the Costa Rican specimens are clearly different from those of Panama and northern 

 Colombia. It will doubtless prove necessary to distinguish the form from Colombia 

 and Panama as Celeus loricatus mentalis (Cassin).
