Pseudobiceros wirtzi sp. nov. (Polycladida: Cotylea) from Senegal with revision of valid species of the genus Author Bahia, Juliana Author Schrödl, Michael text Zootaxa 2016 4097 1 101 117 journal article 10.11646/zootaxa.4097.1.5 4f180553-8a41-4157-902b-8f27fdabcdc2 1175-5326 267125 6149A40D-2514-41D6-ADC9-79677262AC55 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 ).
