Range DescriptionThis species was until recently only known from the vicinity of the type-locality, Cerro Charguayaco, north-east of Cerro Munchique on the Pacific slope of the west Andes in Cauca, south-west Colombia. It was known from four specimens (collected in 1967) and two observations (one doubtful), before being rediscovered at the type-locality in 1997. It appears to be uncommon and incredibly localised, and perhaps difficult to detect; despite not being found further than 300 m from the type-locality during extensive searches within a c.3 km radius at various altitudes (Mazariegos and Salaman 1999), it has now been found elsewhere in Munchique National Park (L. Mazariegos in litt. 2007, T. Donegan in litt. 2008) and at Cerro Charguayaco, Munchique (O. Cortes in litt. 2012). I. It has now also been discovered in the Serrania del Pinche (2,800-3,000 m, with c500 ha of suitable habitat), c.30 km south of the type locality (L. Marzariegos in litt. 2007), and at El Planchón in the Cordillera Occidental, Cauca Department (López-Ordóñez et al. 2008). Males have been observed in April, June-August and November, and females in February-April, July and November (Mazariegos and Salaman 1999, J. Penhallurick in litt. 1999). Other areas of suitable habitat do exist in less accessible areas of the west Andes (Mazariegos and Salaman 1999).
