Abstract

We report additional specimens of Atractus titanicus from three municipalities in the western slope of the Central Cordillera of Colombia. Our reports fill a distribution gap of about 200 km (airline) between Sonsón and Tuluá. This findings support the previous suggestion that A. titanicus is apparently endemic of the western versant of the Central Cordillera and reinforce the idea that boundaries of elevation ranges may constitute an effective barrier to vertical dispersal of some Andean Atractus.

Figures

  • Figure 1. General view of Atractus titanicus (Herpetos-UQ 0413) from Minas del Chaquiro, municipality of Santa Rosa de Cabal, department of Risaralda, Colombia. Photo by Julian Henao.
  • Figure 2. Geographical distribution of Atractus titanicus. Black dots represent previous localities and red dots represent new records.
  • Table 1. Summary of the quantitative morphological variation (meristic and morphometric characters) for known specimens of Atractus titanicus. We use “|″ when the counts were different on both sides of the body, otherwise this character is represented by a single value. Institutional abbreviations of the specimens examined are as listed in Sabaj Pérez (2013), except for Herpetos-UQ which represents the Herpetological Collection of the Quindío University, Armenia, department of Quindío, Colombia. V = ventrals; SC = subcaudals; D2SC = Dorsal on the level 2nd subcaudal; T = temporals; IL+CS = Infralabials contacting chinshields; G = Gular scale rows; SVL = Snout-vent length.
