The Western Amazonian Dwarf Porcupine, Coendou ichillus Voss & Da Silva, 2001, is poorly known in South America. The species is known only from eight localities in the Amazon and Orinoquia regions of Brazil, Colombia, Ecuador, and Peru. In Colombia, it is known from one locality in the Orinoquía region, based on a specimen collected in 1956. We present a new distribution record which adds information about the presence of C. ichillus in the Napo Moist Forests ecoregion, in the Department of Putumayo, Amazon region of Colombia. We suggest that C. ichillus is more widely distributed in the Amazon region of the country. However, based on the number of known records to date, C. ichillus is the rarest species of porcupine.
