The head, or cephalic region, is distinguished by a rolled up and dilated "neck" with the ventral surface facing outwards, with glandular cushions.

The dorsal side of the body is a light ivory base color, with several sepia brown spots that are generally merged with each other.

A light ivory midline can either extend the length of the body or be exclusively in the front region.

[2] It is distinguished from other members of Choeradoplana by its ivory color and brown spots, its red-orange front tip, part of the longitudinal cutaneous musculature being sunken in the ventral parenchyma, the prostatic vesicle having a paired extrabulbar dish-shaped portion, the vesicle also having an elongated intrabulbar portion with an irregular epithelium, a short copulatory apparatus, and an equal size between the male and female atria.

[2] The specific epithet, riutortae, was given in honor of Professor Marta Riutort, for her "contributions to understanding the evolution of flatworms".
