Girardia
Girardia is a genus of freshwater triclad belonging to the Dugesiidae family.
Until 1991 Girardia was considered a subgenus of Dugesia, then it was upgraded to the genus rank.[1] Many works are still using incorrectly the old genus for some Girardia species, mainly for Girardia dorotocephala and Girardia tigrina.[2][3][4][5]
