ABSTRACT Ongoing studies of the iconic Rattlesnakes (Crotalinae) identified a number of reproductively isolated populations worthy of taxonomic recognition. Prior to this paper being published, they were as yet unnamed. These studies and taxa identified and formally named herein are following on from earlier papers of Hoser in 2009, 2012, 2016 and 2018, Bryson et al. (2014), Meik et al. (2018) and Carbajal Márquez et al. (2020), which besides naming new genera and subgenera, also named a total of 9 new species and 3 new subspecies. The ten new species and eight new subspecies identified as reproductively isolated and named in accordance with the International Code of Zoological Nomenclature (Ride et al. 1999) are as follows: 1/ Two north-central Mexican populations of Crotalus (Sayersus) scutulatus (Kennicott 1861) are named as new species in line with the populations identified in earlier studies including Watson et al. (2019). 2/ A population until now treated as a form of Uropsophus armstrongi Campbell, 1979 from the mountains of southern Nayarit and adjacent Jalisco, Mexico, that is geographically and morphologically divergent is formally named as a new species. Another population from Michoacán, Mexico, is formally named as a subspecies of U. armstrongi. 3/ Five Mexican populations previously assigned to either Uropsophus lepidus (Kennicott 1861) or U. lepidus klauberi (Gloyd, 1936) are formally named as new species, with both the preceding taxa also treated as separate species. A further Mexican population is formally named as a subspecies. 4/ Cottonus pricei (Van Denburgh, 1895) of Mexico is formally split three ways with a new species being named and another form resurrected from synonymy. 5/ Three subspecies in the Matteoea mitchelli (Cope, 1861) complex are formally named for the first time, two from the USA and one from Baja California Sur, Mexico. 6/ A southern population of Piersonus brunneus Harris and Simmons, 1978 from Mexico is herein identified and named as a new subspecies, P. brunneus bartletti sp. nov.. 7/ One new species and two new subspecies within Caudisona Laurenti, 1768 are formally named. Scientific recognition of relevant forms is the most important first step in ensuring the long-term conservation of these potentially vulnerable native forms as previously outlined by Hoser (2019a, 2019b).
