Anterior dorsal head scales large and regular, consisting of paired or both paired and azygous scales; posterior edge of head with a projecting series of enlarged, flattened, conical scales (Fig. 4); body scales of middorsal row much enlarged and pointed, forming a serrate dorsal crest (McCoy 1968).

CommentDistribution: erroneously reported by Smith & Laufe 1945 from “Guanajuato: Huasteca Potosina” which is actually not in Guanajuato but in San Luis Potosí and neighboring states (V. Mata-Silva, pers. comm. 26 March 2018). 
EtymologyThe specific epithet is derived from the Latin words serratus, meaning "toothed like a saw," in reference to the serrated posterior edge of the head casque (Lemos-Espinal & Dixon 2013).
