SALAZAR-BRAVO, Jorge; VARGAS, Julieta; JIMENEZ-RUIZ, Agustín y SAVAGE, Jay M.. A new record of Atractus boettgeri (Serpentes: Colubridae), with notes on taxonomy and natural history. Rev. Mex. Biodiv. [online]. 2010, vol.81, n.3, pp.925-929. ISSN 2007-8706.
We report a range extension of Atractus boettgeri, a rare snake endemic to Bolivia. This species differs from Atractus taeniatus by a higher segmental count (well outside the range for A. taeniatus) and by having only 6 maxillary teeth as opposed to 8-9 in A. taeniatus. In addition, A. boettgeri differs from A. emmeli in having 6-6 supralabials (versus 7-7) and fewer ventrals (175-177 versus 181-189 in females). All known records of A. boettgeri indicate an association between this species and the Cerrado vegetation of central Bolivia. This report is also unique in that the specimen reported herein was found in the stomach of a Common Long-Nosed Armadillo (Dasypus novemcinctus).
