Natural History

In Costa Rica I have collected this species twice. Both collections were from seasonal dry forest habitats, in Winkler samples of sifted leaf litter from the forest floor. One collection was from Finca La Pacifica, in a patch of riparian forest, and the other was from Santa Rosa National Park, in the "bosque humedo."


The Costa Rican specimens closely match specimens I collected from the Santa Marta area of Colombia. The type locality of bugnioni is Colombia.
