IRCF REPTILES & AMPHIBIANS • 19(1):1–10 • MARCH 2012 among six continental subspecies, suggested that two distinct clades existed, and proposed a division into at least two addi- tional species, Boa constrictor from mainland South America east of the Andes and Boa imperator to the north and west of the Colombian Andes through Central America and México. Their conclusions, however, must be considered tentative, since they were based solely on a partial mitochondrial gene obtained mostly from captive animals. The Argentine Boa Constrictor (Boa constrictor occiden- talis) represents the southernmost taxon in this complex, inhabiting the Great Chaco region from Paraguay to central Argentina and presumably Bolivia (Waller et al. 1995, Di Cola et al. 2008). Chébez et al. (2008) suggested that, due to morphology, distribution, and ecology, this subspecies should be re-elevated to full species status as originally described (Philippi 1873). This subspecies did exhibit the most distinct haplotype within the South American Boa constrictor clade in the study by Hynková et al. (2009). With a maximum size of about 3 m in total length, the Argentine Boa Constrictor is undoubtedly the most conspic- uous terrestrial snake in Argentina. It is present in the cul- ture of the local human communities that share its habitat. Traditionally hunted by local inhabitants for its fat, to which medicinal properties are attributed (Bolkovic 1999), it also The Argentine Boa Constrictor (Boa constrictor occidentalis) can attain total has been exploited on a large scale due to the high value of lengths to 3 m and masses to 18 kg; Guadalcazar, Province of Formosa. its skin, which is used in manufacturing fine leather goods Photograph by Tomás Waller.
