Meet Apnoctomys conicetorum: A Newly Described Mammal
Scientists have officially described a new mammal species in Argentina, named Apnoctomys conicetorum. This rodent was found less than 130 kilometers from the city of Córdoba. Belonging to the Octodontidae family, it has been classified into its own genus, Apnoctomys. The animal inhabits the rocky slopes of the Chaco forests and occupies a narrow range stretching roughly 120 kilometers in length.
Physical Traits and Habitat
The new species measures about 32–36 centimeters in total body length including its tail, which can reach up to 18 centimeters. Weighing between 115 and 120 grams, Apnoctomys conicetorum features a grayish-brown back and a lighter belly. Its habitat consists of steep, rocky hillsides covered in Chaco woodlands, where bromeliads grow—these plants also form the core of its diet.
The species' range is quite limited, spanning just a few kilometers in width. Part of this area falls within the protected boundaries of a national park and nature reserve. Over three field expeditions, researchers managed to capture only two specimens of Apnoctomys conicetorum, using apple slices as bait. The scientific paper detailing the discovery was published on July 16.
An image of an adult male Apnoctomys conicetorum is available at vertebrate-zoology.
This discovery represents a significant contribution to understanding Argentina's biodiversity. The species' restricted range and specialized habitat point to potential ecological threats, underscoring the need to preserve natural environments. Studying newly identified species like this one can also deepen our knowledge of Chaco ecosystems and their role in global biodiversity.
