Abstract
This paper presents the characters (morphology and aspects of reproductive biology) of a population belonging to the genus Schmidtea, in Romania. This population shows similarities with the other Schmidtea species: with S. polychroa, the presence of cephalic sensory fossae; with S. mediterranea, the asexual reproduction by fission; with S. nova, the presence of a diaphragm of the ejaculatory duct to the secondary seminal vesicle. Set of characters make the population distinct and thus, candidate for a new species: the disposition / arrangement of the genital atria; a wide and straight / narrow and convoluted ejaculatory duct within the penis papilla; in some specimens the penis papilla has two lobes, each with own duct.
