Description.
"Geoplana caraguatatuba" is a flatworm around 60 mm in length and 4 mm in width. The body has parallel margins; the front tip is rounded and the back tip is pointed. The dorsal side has an orange-ochre band running down the middle, bounded on each side by a black line, which joins at the back end; the line is bordered by a white stripe, which is in turn bordered by a black stripe that merges into a grey band with white mottling. A black line borders the margin. The ventral side is a whitish color with black margins.
Along with its coloration, it can be distinguished from other members of "Geoplana" by the penis bulb extending anteriorly 0.8 mm from the penis papilla and the walls of the female atrium not being folded.
