Description

Adults usually attain a length of 64-90 cm, with some growing to 96 cm. The subspecies has a heavy body and a relatively long tail: 16-19% of total body length in males and 13-18% in females.[4]

Geographic range

Found in Mexico in the northeastern states of Nuevo Leon, San Luis Potosí and Tamaulipas.[2] The type locality is "21 km north of Villagrán, Tamaulipas, Mexico."[1]

Conservation status

This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[5] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is unknown. Year assessed: 2007.[6]

Feeding

Feeds primarily on rodents and amphibians. Juveniles are known to employ the yellowish tip of their tail as a lure to attract small insectivorous vertebrates. The yellowish tip fades as the animals mature, as does this behavior.

Taxonomy

Elevated it to species status by Parkinson, Zamudio and Greene (2000) based on mitochondrial DNA sequences.
