ResumoThe taxonomic placement of cantils from Veracruz and Hidalgo, Mexico, has remained uncertain based on the small number of samples available from these areas. We examined the scutellation and color pattern of three new specimens of Agkistrodon taylori from northeastern Hidalgo and adjacent Veracruz and compared these results with the morphology of other A. taylori and the single specimen of Agkistrodon bilineatis lemosespinali from the coastal area of central Veracruz. Our results indicate very little morphological deviation from the range of variation previously reported for A. taylori. In addition, the single specimen of A. b. lemosespinali does not appear to represent A. taylori, contrary to a previous report. However, whether or not it deserves formal recognition as a subspecies distinct from other Agkistrodon bilineatus remains questionable. The presence of A. bilineatus along the eastern coast of Mexico in Veracruz provides support for a previous hypothesis of transcontinental dispersal of A. bilineatus.
