Neotropical Region: Americas, Central America, Costa Rica

Distribution Notes:

Costa Rica: Cordillera de Tilar‡n, upper Pe–as Blancas Valley.


Natural History:

This species occurs in wet forest habitat. I know it from three Winkler samples of sifted leaf litter, from Refugio Eladio and vicinity, 800-1000m elevation, in the Pe–as Blancas Valley.


These collections are curiously similar to P. austroccidua. They have the shagreened face, but the coloration is different and there is no blue reflection. Could this be a local "microspecies" parapatric with the abundant austoccidua just up the hill? Are they the result of hybridization at the edge of the range of austroccidua?
