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

D. 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

D. sicula is known to reproduce sexual and asexually. [1]
