Paratype : IAvH-A(INDERENA)-6425 ( Fig. 9 ). Juvenile male. Colombia , Nariño , Barbacoas , 5 km NW of Altaquer , at Rio Ñambí. Elevation 1400 m . Original collector Paul G. W. Salaman. No collector´s number. 25 August 1991 . Remarks: The original locality published had no specific geographical coordinates for the specimen other than the general survey area at 1°18'N , 7°85'W at 1350 m a.s.l., but the original label had geographical information as 6 km NE road from Altaquer, near the rio Ñambi and coordinates 1°42'N ., 78°55'W ., 1300 m . Both geographical coordinates must be in error since the Rio Ñambi Reserve main cabin is located at 1°18'N ., 78°05'W at 1300 m . The skin was prepared by Guillermo Cantillo, and the paratype specimen label includes morphological information different from the published measurements, which are weight 11g ; exposed culmen 11.2 mm ; bill depth at nostril 3.4 mm , wing chord 54 mm , tail 34.9 mm , and tarsus length 19 mm . Skull ossification 30% and in molt. Soft part colors in the original description. The specimen was partially destroyed by ants in the field after preparation and has the tail detached, and the head almost totally torn.
