Comparisons [conditions for other Epictia in brackets]: By having 188 mid-dorsal scales, the new species has a higher number than E. collaris [155–166] and a lower number than E. albipuncta [213–285], E. alfredschmidti [267–279], E. borapeliotes [256–282], E. columbi [240–265], E. diaplocia [205–233], E. subcrotilla [318–333], E. melanura [395–396], E. rufidorsa [255–270], E. septemlineata , E. striatula [216–265], E. teaguei [232–259], E. tenella [198–299], E. tesselata [258–283] and E. tricolor [285–310]. By having 16 subcaudal scales it further differs from E. columbi [22–25], E. melanura [18–20], E. munoai [10–14], E. nasalis  and E. tricolor [18–23]. By lacking a yellow dorsal blotch on the anterior region of the head this species differs from Epictia septemlineata, E. alfredschmidti, E. borapeliotes, E. clinorostris, E. collaris, E. diaplocia, E. goudotii, E. magnamaculata, E. nasalis, E. peruviana, E. rubrolineata, E. signata, E. striatula, E. subcrotilla, E. teaguei, E. tenella, E. tesselata, E. tricolor, E, undecimstriata and E. vellardi. It further differs from E. septemlineata [dorsum with seven black longitudinal stripes] and E. rubrolineata [dorsum red with 5 longitudinal black stripes] by having a color pattern with grayish-brown dorsal scales with thin white or yellowish margins.
This species does not have striped pattern and multiple colors as mentioned by Adalsteinsson et al. (2009) as diagnostic characters for the genus Epictia, but it shares all other diagnostic characters with its congeners.
|Etymology||This species name is a patronym for Van Wallach, American herpetologist, in recognition of his outstanding contributions towards systematics of the snake family Leptotyphlopidae.|
