Crotalus intermedius gloydi is a venomous pitviper subspecies found in Mexico in the states of Oaxaca and Puebla.[3]


The subspecific name, gloydi, is in honor of American herpetologist Howard K. Gloyd.[4]


This subspecies can be identified by its scalation. It is characterized by having the postnasal scale in broad contact with the first supralabial scale. Also, the postnasal is usually not in contact with any other supralabial scale.[2]
