DistributionMexico (Sonora ?, Nayarit)

Type locality: San Blas near Mazatlan, Sinaloa, Mexico (probably in error and actually San BIas, Nayarit, Mexico).  
TypesHolotype: MDUG (Museo Alfredo Duges, Guanajuato, Mexico), juvenile female, collector unknown 
DiagnosisDEFINITION. A subspecies with usually 20 or fewer large black body blotches, with white centered scales on the lateral surface. The bands are separated by narrow red and white interspaces, which generally have more red dorsally and more white laterally. The venter is white mottled with black, with the edges of the primary blotches extending laterally to the edges of the caudals. At midbody the interspaces are normally one-third the length of the body blotches. (Medica 1975) 
CommentSubspecies: The species status of antonii is contested. Dahn et al. 2018 don’t even mention it. See also Rhinocheilus lecontei.

Distribution: not in Sonora fide Lemos-Espinal et al. 2019 although Heimes 2016 mentions it for S Sonora. Not in Sinaloa (Lemos-Espinal & Smith 2020).
