Species Description

The Guerreran Long-tailed Rattlesnake was discovered in 2008 from a small population in the municipality of Técpan de Galeana in the Sierra Madre del Sur mountain range. Long-tailed rattlesnakes are considered lower montane habitat specialists and reside in the ecotone of tropical deciduous to pine-oak forests. They are likely a nocturnal species, as the first specimen was collected at night; however, further research into its ecology is needed.

Of the discovered species, the Guerrocan Long-tailed Rattlesnake possesses the longest tail proportional to its body length. The tail length of this rattlesnake is 15% of its total body length! Additionally, the Guerreran long-tailed rattlesnake possesses one of the smallest rattles of the rattlesnakes.
