Thorius narisovalis is a species of salamander in the family Plethodontidae. It is endemic to Mexico and only known from near its type locality, Cerro San Felipe, Oaxaca. [2] Its natural habitats are cloud forests and mixed forests. It lives under bark or under fallen trees. [1]

Salamander order of amphibians

Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All present-day salamander families are grouped together under the order Urodela. Salamander diversity is most abundant in the Northern Hemisphere and most species are found in the Holarctic ecozone, with some species present in the Neotropical zone.

Mexico country in the southern portion of North America

Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.

Oaxaca State of Mexico

Oaxaca, officially the Free and Sovereign State of Oaxaca, is one of the 31 states which, along with Mexico City, make up the 32 federative entities of Mexico. It is divided into 570 municipalities, of which 418 are governed by the system of usos y costumbres with recognized local forms of self-governance. Its capital city is Oaxaca de Juárez.

The species is negatively impacted by habitat loss caused by logging, agriculture, and human settlement. It has, however, declined even in suitable habitat. [1]
