Chiapas specimens are quite identical with those from Vera Cruz, Puebla, and 

 Oaxaca; Guatemalan examples (of which none of the nine specimens examined are 

 sexed) are somewhat brighter colored above, the back more chestnut (but less so 

 than in Costa Rican examples, H. p. piitieri), though the pileum is grayish brown, 

 as in Mexican specimens.
