Gigantea is a genus of land planarians from the Neotropical realm.
Description
Species of Gigantea have a large, broad and flat body. The copulatory apparatus has a permanent penis and the ovovitelline ducts enter the female atrium from below.[1] This definition, however, is incomplete regarding the anatomical features currently considered in the definition of planarian genera and Gigantea is certainly a heterogeneous genus.[2]
Etymology
The name Gigantea (Latin for "giant") comes from the specific epithet, gigantea, of the type-species, originally described as Geoplana gigantea due to its large size.[1]
Species
Currently, there are 14 species assigned to the genus Gigantea:
- Gigantea bistriata (Hyman, 1962)

- Gigantea idaia (Du Bois-Reymond Marcus, 1951)
- Gigantea maupoi Carbayo, 2008
- Gigantea montana (Hyman, 1939)
- Gigantea picadoi (de Beauchamp, 1912)
- Gigantea ronaldsluysi Carbayo, 2023[3]
- Gigantea sandersoni (Prudhoe, 1949)
