Crotalus lepidus maculosus, the Durangan rock rattlesnake, is a Mexican subspecies of the rock rattlesnake, a venomous species of pit viper.[1]
The Durangan rock rattlesnake can be distinguished from its sister subspecies as it displays an average of 29-31 small oval spots on its sides which the other subspecies lack, with the ground colour between the spots being heavily pigmented. It also has a difference in numbers of specific scales, as well as being smaller than its adjacent subspecies.[2]
