Type locality: Not given in original description; given as "Canon Prieto, a locality near Fort Whipple [Yavapai County], Arizona" by Coues In Wheeler 1875: 608, and as "Canyon Prieto, Yavapai County, Arizona" [USA], by Klauber, 1956, Rattlesnakes, 1st ed., 1:708 pp.[38].

Reproduction | viviparous. |
Types | Holotype: USNM 6606 (pyrrhus) Holotype : SDNHM = SDSNH 37447; paratypes SDNHM = SDSNH [muertensis] |
Diagnosis | |
Comment | Venomous!
Synonymy: Grismer (1999) elevated angelensis and muertensis to full species status based on aspects of coloration, squamation, and size using an evolutionary species concept. However, he provides details only on some body measurements which are of little use without a larger number or specimen. Meik et al. 2015 found that muertensis nested within pyrrhus and thus considered both as synonymous. Listed as synonym of Crotalus mitchellii by WALLACH et al. 2014: 194.
Nomenclature: Hoser’s 2009 classification and nomenclature has been rejected as unnecessary and unavailable by WÜSTER & BERNILS 2011.
