Distinguished from E. cenchria and E. alvarezi by having barely conspicuous parietal crest, and reduced alary process of vomer; from E. alvarezi by having inverted hemipenis bifurcates after 7th subcaudal; from E. assisi by having lobes slightly smaller than hemipenial body, approximately twice longer than wide, lobes slightly clavate, ventrals generally , 245 scales. Refer to Tables 6–7 for additional diagnostic features of the continental Epicrates. 
CommentSynonymy mostly after PASSOS & FERNANDES 2008.
