TypesHolotype: MZFC 29654 (field number UOGV 1438), adult male, collected 9 September 2007 by U.O. García-Vázquez, M. Trujano-Ortega, and A. Contreras-Arquieta. Paratypes. 15 specimens; all from the municipality of Cuatro Cie ́negas, Coahuila, Mexico:13 (MZFC29655–66, 29669) from the same locality as the holotype and two (MZFC 29667–68) from Pozas Azules, Rancho Pronatura (26849032.90 0N, 102801020.90 0W; datum 1⁄4 WGS84), 714 m elevation. 
DiagnosisDiagnosis: Gerrhonotus mccoyi sp. nov. can be distinguished from its congeners by a combination of characters which includes the presence of a cantholoreal scale (72%; n = 16), a dark mark extending anteriorly from the lower temporal scales through the lower border of the orbit to the preocular or cantholoreal scales, keeled dorsal scales, usually (75%; n = 16) 7–9 dorsal cross-bands mostly interrupted or barely discernible on middorsum (few cross-bands continuous, noticeable across middorsum in some specimens; midsection of cross-bands paler, narrower than the lateral sections), usually indiscernible vertical dark bars on the lateral fold (few, faint bars occasionally present), and black flecks scattered on the venter.
