Psocopterans are insects that have been recorded from all zoogeographic regions but have more species in the tropics. We studied their diversity of in four habitats (Beaches, Village, Trails and Arboreal strata) at the Gorgona National Natural Park, Colombia, from samples collected during November 2009 and October 2010. We added the arboreal Psocoptera collected by canopy fogging in November 2007. The specimens collected were identified to genus and/or to species or morphospecies level. Comparisons were made of the richness and diversity among sites. Although there was no significant difference in the diversity estimated by the Shannon-Wiener index, high species richness and abundance were recorded for the Beaches and Village habitats. The psocid community of Gorgona occurs mainly where vegetation cover is low. Rev. Biol. Trop. 62 (Suppl. 1): 257-264. Epub 2014 February 01.
