Hah. S. Mexico, Central America, Ecuador, Peru, and Bolivia. 



The strong olivaceous colour below and large triangular spots 

 render this species at once distinguishable from all its congeners 

 except D. triatiijidaris, from which it only differs in its lower back 

 being ferruginous red like the tail. In Costa Rica and Veragua the 

 dorsal spots are usually evanescent {D. puHdiinda), but reappear in 

 specimens from Panama and S. America.
