VAN DER HEIDEN, Albert M.  e  FLORES-VILLELA, Oscar. New records of the rare Sinaloan Long-tailed Rattlesnake, Crotalus stejnegeri, from southern Sinaloa, Mexico. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.4, pp.1343-1348. ISSN 2007-8706.  https://doi.org/10.7550/rmb.35729.

Three specimens of the rare Sinaloan Long-tailed Rattlesnake, Crotalus stejnegeri, were obtained from Concordia, southern Sinaloa, Mexico. Morphometric and scalation data were compared with information available from recent literature, and aspects of geographical distribution, legal protection, activity patterns, coloration, and rattle sound are briefly discussed. These new records extend the lowest elevation limit for this species to 400 m and the maximum known total length to 79.0 cm.
