The Texas spotted whiptail (Aspidoscelis gularis) is a species of long-tailed lizard, in the family Teiidae. The species is endemic to the south central and southwestern United States and northern Mexico. Six subspecies are recognized as being valid.
Geographic range
A. gularis is found in New Mexico, Oklahoma, and Texas, and in the Mexican states of Aguascalientes, Campeche, Coahuila, Guanajuato, Hidalgo, Jalisco, Michoacán, Nuevo León, Querétaro, San Luis Potosí, Tamaulipas, and Veracruz.[1]
Description
The Texas spotted whiptail grows to Script error: No such module "convert". in total length (including tail). It is typically a tan brown or green-brown in color, with a pattern of seven distinct grey or white stripes that run the length of the body, and stop at the tail, with light colored spots along the sides. The underside is uniformly white in color. Males often have a red-colored throat, blue belly, and black or blue patches on the chest, while females have only a pink-colored throat. The tail is long compared to the body, usually close to three times the body length. The tail is usually a uniform peach or tan color.Script error: No such module "Unsubst".
Behavior and habitat
A. gularis is diurnal[2] and insectivorous. It is highly active and found in a wide variety of habitats, from grassland and semi-arid regions, to canyons and rocky terrain, typically not far from a permanent water source.Script error: No such module "Unsubst". Like many other whiptail lizards, it is capable of tail autotomy, shedding its tail to escape predation.[3]
Reproduction
Breeding of sexually mature A. gularis occurs in the spring, and a clutch of 1-5 eggs is laid in the early summer.Script error: No such module "Unsubst".

Etymology
The subspecific name, rauni, is in honor of American zoologist Gerald George Raun (born 1932).[4]
