Description
Cratera picuia is a flatworm around 30 mm in length and 3 mm in width. The body is elongated, with parallel margins and a pointed back tip. The dorsal side of the body has two pearl-orange paramedian bands separated by an ivory midline band and two oyster-white marginal bands. Each marginal band is divided in half by black-gray spots that become denser towards the back of the body, forming irregular longitudinal stripes. The ventral side of the body is a white color.Aside from its coloration, it is distinguished from other members of Cratera by having a canalicular prostatic vesicle located inside the penis bulb, and an ejaculatory duct that is not distally dilated.
