The Chihuahuan spotted whiptail (Aspidoscelis exsanguis) [1] is a species of lizard native to the United States in southern Arizona, southern New Mexico and southwestern Texas, and northern Mexico in northern Chihuahua and northern Sonora. [2]

Contents

The species is believed to be the result of extensive hybridization between the little striped whiptail, Aspidoscelis inornatus , the plateau spotted whiptail, Aspidoscelis septemvittatus , and the western Mexico whiptail, Aspidoscelis costatus . It is one of many lizard species known to be parthenogenetic. [2]

Description

The Chihuahuan spotted whiptail grows from 9.5 to 12 inches in length. It is typically a reddish-brown in color, with six lighter colored stripes that run the length of the body, with spotting between the stripes. The underside is white or sometimes pale blue. It is slender-bodied with a tail nearly three times its body length.

Biology

Like most whiptailed lizards, the Chihuahua spotted whiptail is diurnal and insectivorous.

This species can be found in many kinds of mostly arid habitat, including desert, desert grassland, dry basin forests, and oak, pine, and juniper woodland, where it lives in washes and canyons. It digs holes to lay eggs. [3]

Conservation

This is not considered to be a threatened species. [3]

Aspidoscelis is a genus of whiptail lizards in the family Teiidae.

<span class="mw-page-title-main">Western whiptail</span> Species of lizard

The western whiptail is a species of lizard in the family Teiidae. The species ranges throughout most of the southwestern United States and northern Mexico. Most of its populations appear stable, and it is not listed as endangered in any of the states comprising its range. It lives in a wide variety of habitats, including deserts and semiarid shrubland, usually in areas with sparse vegetation; it also may be found in woodland, open dry forest, and riparian growth. It lives in burrows. Major differences between this species and the checkered whiptail include the lack of enlarged scales anterior to the gular fold and the presence of enlarged postantebrachial scales. It was previously known as Cnemidophorus tigris, until phylogenetic analyses concluded that the genus Cnemidophorus was polyphyletic. Since it does not migrate, a number of forms have developed in different regions, several of which have been given subspecific names – for example the California whiptail, Aspidoscelis tigris munda.

<span class="mw-page-title-main">Desert grassland whiptail lizard</span> Species of lizard

The desert grassland whiptail lizard is an all-female species of reptiles in North America. It was formerly placed in the genus Cnemidophorus. A common predator of the whiptail lizard is the leopard lizard, that prey on A. uniparens by using ambush and stalk haunting tactics. These reptiles reproduce by parthenogenesis. In this process, eggs undergo a chromosome doubling after meiosis, developing into lizards without being fertilized. However, ovulation is enhanced by female-female courtship and "mating" (pseudo-copulation) rituals that resemble the behavior of closely related species that reproduce sexually.

Aridoamerica denotes an ecological region spanning Northern Mexico and the Southwestern United States, defined by the presence of the culturally significant staple foodstuff Phaseolus acutifolius, a drought-resistant bean. Its dry, arid climate and geography stand in contrast to the verdant Mesoamerica of present-day central Mexico into Central America to the south and east, and the higher, milder "island" of Oasisamerica to the north. Aridoamerica overlaps with both.

The Laredo striped whiptail is a species of lizard found in the southern United States, in Texas, and northern Mexico in Coahuila, Nuevo Leon, and Tamaulipas. Some sources believe it to be the result of extensive hybridization between the Texas spotted whiptail, Aspidoscelis gularis and the six-lined racerunner, Aspidoscelis sexlineatus. It is one of many lizard species known to be parthenogenic.

<span class="mw-page-title-main">New Mexico whiptail</span> Species of reptile

The New Mexico whiptail is a female-only species of lizard found in the southwestern United States in New Mexico and Arizona, and in northern Mexico in Chihuahua. It is the official state reptile of New Mexico. It is one of many lizard species known to be parthenogenetic. Individuals of the species can be created either through the hybridization of the little striped whiptail and the western whiptail, or through the parthenogenetic reproduction of an adult New Mexico whiptail.

The plateau spotted whiptail is a species of lizard found in the southern United States in Texas, and in northern Mexico in Chihuahua and Coahuila. It is known to hybridize with the Eastern Spotted Whiptail, Cnemidophorus gularis, but is considered to be a distinct species due to phenotypic characteristics.

<span class="mw-page-title-main">Common checkered whiptail</span> Species of lizard

The checkered whiptail is a species of lizard found in the southwestern United States in Colorado, Texas and New Mexico, and in northern Mexico in Chihuahua and Coahuila. Many sources believe that the species originated from the hybridization of the marbled whiptail, Aspidoscelis marmorata, the plateau spotted whiptail, Aspidoscelis septemvittata, and possibly the six-lined racerunner, Aspidoscelis sexlineata. It is one of many lizard species known to be parthenogenic. It is sometimes referred to as the common checkered whiptail to differentiate it from several other species known as checkered whiptails.

<span class="mw-page-title-main">Little striped whiptail</span> Species of lizard

The little striped whiptail is a species of lizard found in the southwestern United States and in northern Mexico. A significant amount of research was done on the species during the mid-1990s, with several new subspecies being added, many of which some sources consider to be distinct enough to warrant full species status, and the research is ongoing. It is called little to distinguish it from many other species known as striped whiptails and to indicate that it is the smallest of those species.

The Trans-Pecos striped whiptail is a subspecies of the little striped whiptail lizard. It is found in the semiarid, sandy habitats of the Chihuahuan Desert, in the United States from West Texas across southern New Mexico to Arizona, as well as northern Mexico. It is sometimes referred to as the Arizona striped whiptail or seven-striped whiptail.

<i>Aspidoscelis costatus</i> Species of lizard

Aspidoscelis costatus, also known as the western Mexico whiptail, is a species of whiptail lizard endemic to Mexico, including Guerrero, Morelos, and Puebla in southern Mexico, as well as other Mexican states. Its range spans both temperate and tropical habitats, and even densely populated urban areas. Its common name, the Western Mexico Whiptail, can easily be confused with the Western Whiptail, which refers to a different lizard, Aspidoscelis tigris.

Aspidoscelis sackii, known commonly as Sack's spotted whiptail, is a species of lizard in the family Teiidae. The species is endemic to Mexico. There are three recognized subspecies.
