FIGURE 4. Preserved males of Allobates paleovarzensis showing variation in the dorsal pattern from dark brown head and back to dark brown head changing to light brown back; none of the specimens has dorsal markings. All specimens have a dorsolateral stripe that begins behind the eye in some specimens but on the snout in others. All specimens have a half-moon-shaped paracloacal mark. (Photograph by A.P. Lima)
