Range DescriptionNeomorphus radiolosus is found on the Pacific slope of the West Andes in south-west Colombia (Valle, Cauca, Nariño) and north-west Ecuador (Esmeraldas, Imbabura, Pichincha). It was recorded only rarely until 1988, since when it has been found in three areas in Colombia and at least six in Ecuador (Leck et al. 1980, Best et al. 1996, Hornbuckle et al. 1997, López-Lanús et al. 1999, Jahn et al. 2002, Krabbe & Nilsson 2003, B. Palacios verbally 2005, A. Solano verbally 2007, P. Mena Valenzuela in litt. 2007, Jahn in press a). Hunters in the Junín area, Nariño, reported in the 1990s that they saw it every few months, but it is evidently a low-density species (López-Lanús et al. 1999) and very rare and local (Ridgely and Greenfield 2007).
