Confined exclusively to the southwestern portion of Costa Rica and 

 almost exclusively to the Terraba Valley, although two specimens are 

 known to have been taken farther north, at Pozo Azul de Pirris and 

 Guaitil. I found it most abundant at Boruca, in the second-growth scrub

 other members of the genus and closely allied genera. No nests were 

 observed, I having reached Boruca at the end of the breeding season.
