Description
Choeradoplana eudoxiae is a flatworm around 38 mm in length and 1.5–2 mm in width. It has a slender, subcylindrical body that narrows as it approaches the front tip of the body, with a convex dorsal side and a slightly convex ventral side. The front tip is rounded, and the back tip is pointed. The head region is rolled up. The creeping sole is 75.5% of the body width. The dorsal side of the body is a pastel yellow base color with fawn brown spots; in the paramedian regions of the body, these spots are denser. The ventral side is a cream color. The front tip is a greyish color dorsally and ventrally.It is distinguished from other members of Choeradoplana by its yellow color and brown spots, a lack of any lateral dilations or "neck" separating the head from the rest of the body, the ventral side of the head being concave, a lack of glandular cushions, the extrabulbar portion of the prostatic vesicle having paired branches and an unpaired, rounded section, the intrabulbar portion of the vesicle being a dilated vertical duct, and a lack of a penis papilla.
