Fig. 12 in Systematics of Snakes Referred to Dipsas variegata in Panama and Western South America, with Revalidation of Two Species and Notes on Defensive Behaviors in the Dipsadini (Colubridae)
Fig. 12. Comparison of head shapes and color patterns in Dipsas andiana and Dipsas oreas at equivalent magnifications. Top: D. andiana (KU 132503, 622 mm total length). Bottom: D. oreas (KU 142803, 629 mm total length). Dipsas andiana has a stereotypical Πshaped pattern on the dorsal surface and is relatively unmarked otherwise, whereas D. oreas has irregularly and heavily pigmented dorsal and lateral surfaces of the head. Dipsas oreas also has angular canthal and supratemporal regions and a relatively longer postorbital region than does D. andiana.
