Dendrobates nubeculosus Jungfer and Böhme, 2004

Only known from its type locality, on the Essequibo River, Guyana. May be an arboreal inhabitant that has been completely overlooked. As many colleagues have commented (see Guayasamin et al. 2006 for a resumé), the next realm for exciting discoveries is the exploration of the rainforest high canopy.
