A. minutus ranges from Panamá to Cauca. In fact, minutus southern record is south from this new reserve. Honestly Im not so excited about this new reserve, but maybe this is not the place to discuss it...
Only will say Phyllobates terribilis is maybe the more common of all colombian Phyllobates, living in a big area of well conserved forests. Its a loud secret here, but its real distribution is a lot bigger than the literature says. So, the new reserve, in my opinion, has a strong comercial interest, and ignores the local traditional owners of the land, the afro american communities from Timbiqui. The pacific lowlands are by law a reserve (reseva del pacifico), so buying some hectare in this specific issue wont save the specie, but will work more as a private tourism iniciative, with conservation money.
