Choeradoplana agua is a species of land planarian belonging to the subfamily Geoplaninae.

[1] It is known from specimens found in Desengano State Park in Brazil.

[2] It is distinguished from other members of Choeradoplana by its mottled brown dorsal spots, the proximal portion of the prostatic vesicle being outside of the penis bulb, tubular, and initially bifurcated, the intrabulbar portion being pear-shaped with a folded wall, and having no permanent penis papilla.

[2] The specific epithet of agua is derived from the Tupi language word aguá, meaning "bubble".

This is in reference to the shape of the species' prostatic vesicle.
