| Diagnosis | Diagnosis (ehecatl): A rattlesnake belonging to the Crotalus durissus species complex, characterized as other species by a prominent vertebral process and conspicuous scale tuberculations. The distribution range of C. ehecatl closely approaches to those of C. culminatus and C. simus, and to a lesser extent to C. mictlantecuhtli. Crotalus ehecatl can be distinguished from all members of the Crotalus durissus species complex by exclusive combination of the following characters: paravertebral stripes of two scale rows, usually paravertebral stripes with light center on the nape, length of paravertebral stripes of 22 scales, 31 dorsal body blotches, intercanthal scales in 18.7% (n=16) of specimens, interpreocular scale in 50% (n=16) of specimens, first infralabial scale divided in 18.7% (n=16), postrostral scale in 12.5% (n=16), usually 1 postsupraloreal scale, contact between lacunal and supralabial scales in 56.2% (n =16) of specimens, postocular stripe of three scales, usually with light center, contact between paravertebral stripes and supraocular scales in 68.7% (n=16) of specimens, and a dark prefrontal bar interrupted in 93.7% (n=16) of specimens.

| Comment | Synonymy: partly from CARBAJAL-MÁRQUEZ et al. 2022 (description of C. ehecatl). Reyes-Velasco et al. 2022 strongly suggested to synonymize C. ehecatl with culminatus although they did not explicitly do that, probably because all their ehecatl samples form a monophyletic clade (which is closely related to culminatus). Species group: Crotalus durissus complex, which includes durissus, simus, culminatus, and tzabcan. Habitat: open dry areas with rocky outcrops in tropical deciduous forest and seasonal rain forest. |
| Etymology | The specific epithet “ehecatl”, derives from the Nahuatl word “Ehēcatl” and means “The wind” or “Lord of the wind”. In Mexican mythology (Aztec), Ehécatl is the god of the wind. It is usually interpreted as one of the manifestations of Quetzalcóatl, the feathered serpent, taking the name of Ehécatl-Quetzalcóatl, appearing in the breath of living beings and in the breezes that bring the clouds with rain for the sowings. His breath starts the movement of the Sun, and brings life to what is inert. Also, he clears the way for Tláloc. The species name is used as an invariable noun in apposition to the generic name. |
