Distribution. — Low, moderate, and intermediate elevations of the Atlantic versant from 

 central Nuevo Leon, Mexico, to western Guatemala; also on the Pacific versant in Oaxaca, 

 Mexico. 



Systematic references. — Dixon et al. (In press). 



Remarks. — This taxon was recently revised by Dixon et al. (In Press), who synonymized 

 Tantilla miniata Cope, 1863, and T. morgani Hartweg, 1944, with it. Given the priority of the 

 name miniata over rubra, application will be made to the International Commission on 

 Zoological Nomenclature to conserve the name rubra. Also see the T. cucullata account.
