DiagnosisDIAGNOSIS. A mainland Mexican geographic segment of C. hemilopha with a long middorsal crest reaching to groin and usually with 8 or more whorls of enlarged caudal scales separated from adjacent such whorls by no more than a single intercalary row of scales at any point. (Smith 1972)


Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about between half a page and a page) are available for collaborators and contributors. Please contact us if you need any of this material. 
CommentDistribution: Rorabaugh et al. (2015) mention a report of this species from Nogales, Arizona, which apparently was brought from adjacent Sonora in Mexico. Not in Durango fide Lemos-Espinal (2018). 
EtymologyNamed after Greek makros (μακρός), large, long + Greek lophos (λόφος), neck, crest of hill, ridge, crest of a helmet. [“...A mainland Mexican geographic segment of C. hemilopha with a long middorsal crest reaching to groin...”].
