ResumoA new species of the colubrid genus Geophis is described from the Cordillera Occidental, Departamento del Valle del Cauca, Colombia. This new species is most similar to members of the championi group. It is diagnosed from this group and all other species in Central and South America by the presence of two postocular scales. It is easily distinguished from all other species of Geophis by combinations of features of scalation and by color pattern. This new species occurs sympatrically with the only other species known from South America, G. nigroalbus of the sieboldi group. In the course of herpetofaunal investi- gations in the Departamento del Valle, Co- lombia, numerous specimens of two species of Geophis have been collected. One of these is an undescribed species that differs mark- edly from the more common and sympatric Geophis nigroalbus as well as from all other species in the genus. We describe this dis- tinct taxon as:
