Choeradoplana longivesicula is a species of land planarian belonging to the subfamily Geoplaninae.[1] It is known from specimens found in General Carneiro, Brazil.[2]

Description

Choeradoplana longivesicula is a flatworm around 34โ€“67 mm in length and 4โ€“6 mm in width. It has an elongate body with parallel margins. The head, or cephalic region, has two glandular cushions on the ventral side, separated by a longitudinal slit. The front end of the body is expanded, while the back end is slightly pointed. The dorsal side of the body is a yellowish base color, covered densely by irregular, small, dark brown flecks. The yellowish base is visible on the head and margins, as well as on a longitudinal median stripe that runs down the dorsal side aside from the head. The ventral side is a whitish color.[2]

It is distinguished from other members of Choeradoplana by its dark brown flecks and light midstripe, a bell-shaped pharynx, sperm ducts that open laterally into the proximal wall of the prostatic vesicle, a tubular and unpaired prostatic vesicle that narrows to open through the tip of the penis papilla as an ejaculatory duct, a cylindrical, almost symmetrical penis papilla that fills the entire common atrium, and an oval-elongate, unfolded atrium with no difference between the male and female regions.[2]

Etymology

The specific epithet is derived from the Latin words longus and vesicula, literally meaning "long vesicle", in reference to the species' elongated prostatic vesicle.[2]
