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. This definition, however, is incomplete regarding the anatomical features currently considered in the definition of planarian genera and Gigantea is certainly a heterogeneous genus.
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.
Species
Currently, there are 14 species assigned to the genus Gigantea:
