I am not able to detect any differences of coloration according to geographic area 
except that specimens from Sinaloa, Colima, and Yucatan average slightly paler, 
those from Guerrero and Costa Rica slightly deeper in coloration, these latter ap- 
proaching in intensity of coloration specimens of A. r. corallirosiris from western 
Chiapas and western Guatemala.
