Cratera hina is a species of land planarian belonging to the subfamily Geoplaninae. [1] It is known from specimens found in the Paranapiacaba Conservation Units Mosaic in Brazil. [2]
Cratera hina is a flatworm that can reach up to 60 mm in length. The dorsal side of the body consists of a lateral black band on each side of the body and a median orange band. The frontal margin is black. [2]
Aside from its size and coloration, it is distinguished from other members of Cratera by having a ciliated epidermis both dorsally and ventrally, dorsal eyes that initiate in the head region, a short penis bulb that extends very little anteriorly to the penis papilla, a bifurcated and extrabulbar proximal portion of the prostatic vesicle that is attached from the penis bulb, an ejaculatory duct that isn't distally dilated, a thick muscle tube surrounding the ejaculatory duct with a diameter triple that of the duct, an underlying muscularis of the penis papilla made up of two circular layers with a longitudinal layer in between, the dorsal insertion of the penis papilla being slightly anterior to the ventral one, a penis papilla that projects into the female atrium, the dorsal surface of the male atrium being pierced by several glands, and the lack of a common glandular duct. [2]
The reproductive system of planarians is broadly similar among different families, although the associated structures can vary in complexity.
