This is an endemic species of central Panama, where it is known from a single locality near Altos de Pacora (Myers 2003). The holotype was collected at an elevation of 700 meters (Jaramillo et al. 2010).
This species is known only from the holotype, which was collected in 1964 (Myers 2003).
Range extension and natural history observations of a rare Panamanian snake, Geophis bellus Myers, 2003 (Colubridae: Dipsadinae)
The fossorial snake Geophis bellus is a small Panamanian endemic previously known only from the holotype. Here we report additional specimens, which greatly expand the known range of the species ca. 200 km from the type locality into western Panama. Furthermore, we provide information on sexual dimorphism in some scalation counts and in body and tail size. Finally, we provide information on natural history, including activity period, habitat usage, and reproductive cycle. Such discoveries are important for the development of conservation plans for this species in Panamá.
