Geoplana pulchella

Geoplana pulchella is a flatworm around 30 mm in length and 3 mm in width. The body is elongate and has parallel margins; the front tip is rounded and the back tip is pointed. The front third of the dorsal side of the body is a pure orange color, while the rest of the dorsal side has a light grey band running down the middle, flanked on each side by a black band. The entire dorsal side is speckled with white. The front third of the ventral side is a traffic white color, while the rest is squirrel grey.^[2]

Along with its coloration, it can be distinguished from other members of Geoplana by a 1 mm anterior extension of the penis bulb from the penis papilla, papilla with a length 7–9 times its diameter with a thin tip, and a conspicuous circular muscle fibre mass around the posterior female atrium.^[2]
