*Dugesia sicula* Lepori, 1948

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]

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]
