Atractus attenuates — WALLACH et al. 2014: 68
|Distribution||Colombia (Sabanalarga, Antioquia: northern end of the Cordillera Central), 1000 m elevation.|
Type locality: at Sabanalarga, on Cauca River, [6°51’N, 75°49’W, Department of Antioquia], Colombia. The type locality, Sabanalarga (Nicéforo María, 1942: 87, map), lies on the east bank of the Río Cauca at an elevation of about 1000 m (Paynter, 1997: 372), in the northern end of the Cordillera Central.
|Types||Holotype: AMNH R-19998, an adult male obtained by Hermano Nicéforo Maria on May 16, 1921|
|Diagnosis||DIAGNOSIS: Atractus attenuatus is distin- guished by its exceptionally slender, drawn- out habitus, combined with 17 scale rows, a high ventral + subcaudal count (226), and an extremely vague pattern of numerous, closely spaced, indistinct crossbars. The most relevant comparison is with Atractus sanguineus, which has fewer, more widely spaced crossbars that are distinctly darker than the ground color and that are connected by a vertebral dark line. In life, the dorsal ground color of A. attenuatus is probably brown, whereas A. sanguineus is red. See Comparisons.|
|Comment||Description: Atractus attenuates is a slender, exceptionally attenuated snake 420 mm in total length (adult male holotype), with 17 scale rows. a high ventral + subcaudal count (226), and an extremely vague pattern of numerous, closely spaced, indistinct dark crossbars on a brown ground color.|
|Etymology||ETYMOLOGY: The species name attenuatus is the passive past participle of the Latin verb attenuo (to stretch or make thin), and also (as used here) a derived adjective meaning stretched out and slender.|
