Cratera imbiri is a species of land planarian belonging to the subfamily Geoplaninae.

[1] It is known from specimens found in Campos do Jordão State Park in Brazil.

The front of the body fades into a coral red color on both the dorsal and ventral side.

[2] Aside from its coloration and length, it is distinguished from other members of Cratera by having marginal eyes, a cylindrical pharynx with the dorsal insertion posteriorly shifted at about a fifth of the pharynx's length, a pharyngeal pouch that is very close to the prostatic vesicle, the epithelium of the penis papilla being underlain by a circular muscle fiber layer, a female atrium that is 3.2 times longer than the male and gradually narrows at its posterior, and the presence of a long common glandular ovovitelline duct.

[2] The specific epithet is derived from the former name of Campos do Jordão State Park, Vila de São Matheus do Imbiri, the type locality of the species.
