Comparisons [conditions for other Epictia species in brackets]: By having 10 midtail scale rows this species differs from E. albipuncta, E. striatula, E. unicolor and E. weyrauchi [all having 12]. The presence of a frontal scale differentiates the new species from E. ater (including E. nasalis) and E. bakewelli. The number of 211–221 mid–dorsal scales, distinguishes it from E. alfredschmidti [267–279], E. antoniogarciai [195–208], E. australis [233–282], E. bakewelli [225–262], E. borapeliotes [256–282], E. clinorostris [240–256], E. collaris [155–166], E. columbi [242–265], E. goudotii [224–260], E. hobartsmithi [191–208], E. melanura [395–396], E. peruviana [185–199], E. rufidorsa [256–270], E. septemlineata , E. subcrotilla [318–333], E. teaguei [223–259], E. tesselata [261–273], E. tricolor [276–310], E. unicolor , E. vanwallachi , and E. vellardi [224–255]. The number of 17–19 subcaudal scales differentiates this species from E. alfredschmidti [14–16], E. clinorostris [10– 16], E. columbi [22–25], E. munoai [10–14], E. nasalis , E. rubrolineata , E. septemlineata , E. vanwallachi , and E. vellardi [13–16]. By the presence of a yellow dorsal blotch on the rostral this species further differs from E. columbi, E. rufidorsa, E. vanwallachi, and E. weyrauchi, and the presence of a yellow terminal spine distinguishes it from E. columbi, E. melanura, E. munoai, E. rufidorsa, and E. septemlineata. By lacking a striped dorsal color pattern the new species can be distinguished from E. albifrons, E. albipuncta, E. alfredschmidti, E. amazonica, E. australis, E. bakewelli, E. borapeliotes, E. clinorostris, E. diaplocia, E. fallax, E. goudotii, E. magnamaculata, E. melanoterma, E. munoai, E. phenops, E. rubrolineata, E.rufidorsa, E. septemlineata, E. subcrotilla, E. striatula, E. teaguei, E. tenella, E. tesselata, E. tricolor, E. undecimstriata, and E. vellardi. The color pattern where each body scale is black on the anterior half and yellow on the posterior half, with black margins dorsally and yellowish margins ventrally differentiates the species from E. antoniogarciai [dorsal body scales black, each scale with yellowish-white or bright yellow outlines], E. ater [blackish-brown to blackish above; ventral surface a lighter brown], E. collaris [color brown, dorsally slightly darker than ventrally; all scales with a dark-brown area at the base and a light-brown posterior edge], E. columbi [dorsal scales very dark brown in solid color without lines, punctuations or light borders], E. melanura [general color brown, a little lighter beneath, the outlines of the scales lighter], E. nasalis [above light brown, the color lighter on the ventral surface], E. peruviana [dorsum and venter uniformly dark reddish, each scale with thin white outlines], E. signata [dorsal scale rows uniformly brown, ventral scales light brown], E. unicolor [reddish-brown, each scale edged light-colored], and E. vanwallachi [dorsal scales brown with thin white or yellowish outlines].
|Etymology||The species name venegasi is a noun (genitive case) and a patronym for Pablo Venegas, Peruvian herpetologist, in recognition of his important contributions to the systematics of amphibians and reptiles from his home country.|
