A new species of Geophis (Dipsadidae) from Veracruz, Mexico, with comments on the validity of related taxa

A new species of the Geophis dubius group is described from the cloud forests in the mountains north of Xalapa, Veracruz. This new species is most similar to G. turbidus and G. lorancai, from which it differs genetically as well as by a very unique color pattern, morphological characters, and habitat use. The validity of G. fuscus, which was described from central Veracruz, is discussed. With the description of the new species and our assessment of G. fuscus, the number of species in the Geophis dubius group increases to 14 and the number of species of Geophis to 52.
