Pseudobiceros schmardae Faubel, 1984

Taxonomic remarks. The name was created to resolve confusion that resulted from the original description of Prosthecereus latissimus (Schmarda 1859). Drawings of the type material show that two different animals were described under the same name; one clearly refers to Prosthecereus (Stummer-Traunfels 1933, fig. 103a) as it was illustrated by Schmarda (1859, p. 32); and the other animal with two male gonopores (fig. 103b) shows characteristics typical for Pseudobiceros. The species was entirely put under Pseudoceros and the variation of number of gonopores was considered a plastic character (Stummer-Traunfels 1933, Marcus 1950). With the creation of the genus Pseudobiceros, Faubel (1984) created the new name to encompass the flatworm described by Schmarda and illustrated with two male gonopores. The species was not considered in Newman & Cannon’s (1994, 1997) revisions. However, we support it is a valid species (Table 1).
