Range Description

Central and eastern Panama extending into Colombia. The exact western limit is not clearly defined, but marked by Reid (1997) at just a little west of the Canal Zone. Their range it seems is restricted to the east of the Azuero peninsula.

In discussing habitat preference in Panama, Moynihan (1970) stated that “Rufous-naped tamarins are abundant in some parts of the Pacific coastal region, and also occur in some central areas approximately equidistant from both coasts. To my knowledge, however, they are completely absent from the whole of the Atlantic coast of the isthmus, except for one small, highly modified or “unnatural” area.” (p.2). The exception he mentioned is around the Canal Zone, the city of Colón, and Lake Gatún where the original forest has been almost entirely destroyed, and Moynihan (1970, 1976) argued that their occurrence there is the result of a recent range extension. The map of localities provided by Hershkovitz (1977, p.915) confirms Moynihan’s observation, with only two records on the Atlantic side of the isthmus except in the vicinity of the Canal Zone. The two outlying Atlantic coast records listed in the gazetteer (p.925) are: Locality 6c, San Blas, Mandinga, 9º27'N, 79º04'W, C. O. Handley, Jr., May 1957, a series of six specimens in the American Museum of Natural History, New York; and locality 6d, San Blas, Armila, Quebrada Venado, 8º40'N, 77º28'W, C. O. Handley, Jr. February-March 1963, a series of 12 specimens, also in the US National Museum. Moynihan (1970, 1976) suggested that their absence from the Atlantic coast was related to a preference for drier forests (“of moderate humidity”) typical of the Pacific coast. Skinner (1985) confirmed their occurrence in San Blas and reported the presence of S. geoffroyi in 21 sites all in moist tropical forest from the western Río Chagres basin to the Darién, from the Atlantic to the Pacific coasts.

In Colombia it occurs along the Pacific coast, south as far as the Río San Juan. The Río Atrato was believed to be the eastern limit to its range (Hernández-Camacho and Cooper 1976; Hershkovitz 1977), but Vargas (1994, cited in Defler 2003) found the species occurring around the National Natural Park of Las Orquídeas in the vicinity of the village of Mandé, Antioquia, at elevations as high as 1,000 m, extending its range to the west of the upper Río Cauca. Barbosa et al. (1988, in Mast et al. 1993) also recorded the species at Quibdo, a town just east of the upper Río Atrato.
