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]
