Dugesia sicula is a species of dugesiid triclad that lives in freshwater bodies of the Mediterranean Basin, where it is widely distributed. It has been reported from Sicily,[1] Elba and Mallorca,[2] Eivissa,[3] Sardinia,[4] Algeria,[5] Tunisia,[6] Morocco[7] and Crete.[8]

Morphology
editD. sicula individuals have an asymmetrical penis papilla, with a diaphragm at the base, separating the seminal vesicle from the ejaculatory duct. This duct is ventral and it opens subterminally. The seminal vesicle is wrapped by a thin layer of bulbar muscles. The penis papilla is weakly muscular and more parenchymatic.[8]
Reproduction
editD. sicula is known to reproduce sexual and asexually.[1]
