Crotalus transversus is a venomous pit viper species found in central Mexico, known from less than 20 specimens.[2] No subspecies are currently recognized.[3]


Adults grow to a maximum recorded length of 46.5 cm (18.3 in) (for a female). The length of the tail represents 10.5% of total body length in males and 7.1-7.9% in females.[2]

Geographic range[edit]

It is found in central Mexico in the Sierra Ajusco and the Sierra de Monte Alto of the Transverse Volcanic Cordillera in the states of México and Morelos at elevations exceeding 2,900 m (9,500 ft) in temperate boreal forests. The type locality given is "about 55 km. SW México (city), near Tres Marías (Tres Cumbres), Morelos [Mexico], elevation about 10,000 ft." (3,000 m)[1]

Conservation status[edit]

This species is classified as Least Concern on the IUCN Red List of Threatened Species (v3.1, 2001).[4] Species are listed as such due to their wide distribution, presumed large population, or because they are unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend was stable when assessed in 2007.[5]
