Summary. – The large-nosed wood turtle, Rhinoclemmys nasuta (Family Geoemydidae), is a small to medium-sized aquatic turtle (carapace length to 228 mm) found in a variety of northwestern South American water bodies, including small streams and rivers. It has a restricted distribution in the Chocoan rain forest of Pacific coastal Colombia and Ecuador. The species is known to have a primarily herbivorous diet, but small invertebrates are also eaten. Females lay one large egg per clutch. Adults exhibit female-biased sexual size dimorphism, and growth to maturity is protracted, with estimates varying from 12 to 14 years for males and females, respectively. Although its conservation status has not been studied thoroughly, the species is eaten on a subsistence basis, but it is not thought to be threatened by commercialization. Deforestation within the species range has not been studied with respect to its effect on this highly aquatic species. This species occurs in one protected area in Ecuador and may occur in others in Colombia. Distribution. – Colombia, Ecuador. Confined to the Chocoan rainforest area in Pacific coastal drainages of northwestern Ecuador and western Colombia, and the middle and upper portion of the Caribbean-draining Río Atrato basin in northwestern Colombia. Synonymy. – Nicoria nasuta Boulenger 1902, Geoemyda nasuta, Geoemyda punctularia nasuta, Rhinoclemmys punctularia nasuta, Rhinoclemmys nasuta, Callopsis punctularia nasuta, Callopsis nasuta. Subspecies. – There are no recognized subspecies. Status. – IUCN 2009 Red List Status: Near Threatened (LR/nt) (assessed 1996, needs updating); CITES: Not Listed; Colombian Red Data Book: Data Deficient.
