The systematic position of Scolodonta Döring, 1875 and Scolodontidae H. B. Baker, 1925 (Gastropoda: Pulmonata)

Scolodonta semperi (Döring, 1875) from Argentina is redescribed. The aulacopod foot, the branching of the penial retractor from the columellar muscle, the elongated kidney and the lack of corneous hooks inside the penis show that Scolodonta Döring, 1875 has to be classified in the Systrophiidae Thiele, 1926. Thus, the family has to be called Scolodontidae Baker, 1925. There are only minor differences between Scolodonta semperi and Systrophia lutea Tillier, 1980, the type species of Wayampia Tillier, 1980. Thus, Wayampia Tillier, 1980 becomes a synonym of Scolodonta Döring, 1875.
