Cratera cuarassu is a species of land planarian belonging to the subfamily Geoplaninae. [1] It is known from specimens found in Desengano State Park, Brazil. [2]
Cratera cuarassu is a flatworm around 11 cm in length and 0.6 cm in width. It has parallel body margins. The front end of the body is rounded, while the back end is pointed. The dorsal side of the body is a black-blue color, with a submarginal zinc-yellow stripe on each side of the body, running almost from end to end. The ventral side is a light ivory color, becoming a brown-beige at the front end. [2]
It is distinguished from other members of Cratera by its coloration along with the peculiar shape of the male organs; specifically, a short, wide penis papilla that projects vertically downwards from the male atrium roof, and the possession of a large intra-penial cavity. [2]
The specific epithet, cuarassu, is derived from the Tupi language words cuara, "hole, cave", and assu, "large"; this is in reference to the species' large intra-penial cavity. [2]
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, Obama nungara has been introduced in Europe.
Luteostriata is a genus of land planarians from Brazil characterized by a yellow body with dark longitudinal stripes.
Obama is a genus of land planarians from South America. It contains several species adapted to human-disturbed environments, including the only invasive land planarian native to the Neotropical realm, Obama nungara, which has been accidentally introduced in Europe.
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
