ABSTRACT
Two new species of freshwater triclads belonging to the Dugesia gonocephala species group are described, D. golanica n.sp. from northern Israel and D. libanica n.sp. from Bécharré in northern Lebanon. D. golanica is characterized by a large, solid, bilobed adenodactyl positioned dorsally and to the right of the pointed penis papilla, while D. libanica has a large, solid, conical-shaped adenodactyl situated dorsally and to the right of the asymmetrical, finger-shaped penis papilla. These two species are clearly related to each other and to D. iranica (Livanov) from Iran and Turkey.
