Holotype. USNM 54760, collected by F.J. Dyer in April 9, 1916, from Útila Island (16o 06’N, 0 86o 55’W), Honduras.

Diagnosis. Epictia magnamaculata is distinguished from all congeners by the following combination of characters: snout slightly truncate in dorsal and ventral view, rounded in lateral view; supraocular present, not in contact with first supralabial; first supralabial longer, reaching eye level; rostral scale subtriangular in dorsal view; ocular hexagonal with straight shape at the eye level; supraocular longer than frontal scale; temporal indistinct; fused caudals absent; two supralabials (1+1); four infralabials; 245–262 middorsal scales; 237–246 midventral scales; 15–18 subcaudal scales; 10 scales around the middle of tail; seven dorsal scale rows dark brown in the centre of scales with paler border forming longitudinal zig-zag lines; seven lateroventral scale rows brown in the centre of scales with border lighter forming soft zig-zag lines; gular region paler than venter.

Variation. Middorsal scales 245–262 (x¯ = 252.6 ± 4.9, n = 12); midventral scales 237–246 (x¯ = 240.3 ± 4.0, n = 4); subcaudal scales 15–18 (x¯ = 16.8 ± 1.1, n = 13); TL 98–195 mm (x¯ = 154.5 ± 28.3, n = 12); TL/TAL ratio 14.1–21.0 (x¯ = 16.9 ± 1.8, n = 12); TAL 4.8–7.1% of TL (x¯ = 6.0 ± 0.0, n = 12); TL/MB ratio 52.7–61.5 (x¯ = 57.9 ± 3.7, n = 4); TAL/MT ratio 2.8–4.0 (x¯ = 3.5 ± 0.6, n = 4); relative eye diameter 1.3–2.5 (x¯ = 1.9 ± 0.5, n = 4); rostral width 0.4–0.5 (x¯ = 0.4 ± 0.0, n = 4).

Distribution. In Colombia, known form the Archipelago of San Andrés, Providencia y Santa Catalina in the Providencia (13º20’56”N 81º22’29”) and San Andrés (12º35’N 81º42’W) islands (Fig. 3).
