The new species is most similar to G. duellmani and G. turbidus, which are endemic to the mountains of northern Oaxaca and the Sierra Madre Oriental of Puebla and Hidalgo, respectively. However, the new species differs from G. duellmani by the presence of postocular and supraocular scales and from G. turbidus by having a bicolor dorsum. With the description of the new species, the species number in the genus increases to 50 and to 12 in the G. dubius group. Additionally, a key to the species of the G. dubius group is provided.
