). The region where this species was found is undergoing an intense process of urbanisation, and many areas are occupied by livestock and agriculture activities, leaving few areas with natural conditions. In addition, neighbouring streams are under intense environmental decline caused by new roads and urban pollution, making the habitat of the new species highly vulnerable.
