Coffee Grove Salamander

The Coffee Grove Salamander (Aquiloeurycea cafetalera) is a small, fully terrestrial plethodontid salamander in the family Plethodontidae, endemic to the cloud forests and coffee agroforestry zones of the Sierra de Juárez in the Mexican state of Oaxaca. Like all plethodontid salamanders, it is lungless, relying entirely on cutaneous gas exchange through its moist skin, making it exquisitely sensitive to desiccation and temperature changes. Adults are slender, with a reddish-brown dorsum and light-coloured venter, typically measuring 5–8 centimetres in total length. The species inhabits cool, humid cloud forest floor environments and the leaf litter and bark of shade-grown coffee plantations at elevations approximately between 1,500 and 2,500 metres—an association that gives it its common name. The presence of this salamander in coffee agroforestry systems highlights the biodiversity value of traditional shade-grown cultivation compared to sun-grown monocultures. The Coffee Grove Salamander is classified as Vulnerable by the IUCN due to its restricted distribution, estimated extent of occurrence below 5,000 square kilometres, and ongoing threats from habitat loss through deforestation, conversion to sun-grown coffee cultivation, and climate-driven changes to cloud forest conditions. No ex situ conservation programmes are known to be in place.
