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

[1] It is found in areas within the Atlantic Forest in Brazil, such as Serra da Bocaina National Park and in municipalities such as Teresópolis, São José do Barreiro, Salesópolis, and Ribeirão Pires.

[2] It is distinguished from other members of Choeradoplana by the dorsal color being mottled with brown speckles, the sperm ducts penetrating the frontal-side wall of the penis bulb, a prostatic vesicle within the penis bulb with a canalicular, sinuous and back-oriented proximal half, a relatively long copulatory apparatus, and no permanent penis papilla.

Additionally, the male atrium is elongate and lined with a ciliated epithelium underlain by a spongy tissue.

[2] The specific epithet of pucupucu is derived from the Tupi language word of the same name, meaning "very long".
