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 Genus Pseudobiceros Faubel, 1984 Type species: Pseudobiceros strigosus ( Marcus, 1950 ) junior synonym of Pseudobiceros gratus ( Kato, 1937 ) Taxonomic remarks. The confusion about the genus Pseudobiceros begins with its type species. Pseudoceros strigosus was a name created by Marcus (1950) to solve confusion resulted from the misuse of the specific name striata (in the originally Eurylepta description (Schmarda 1859)) or striatus (after it was relocated in Pseudoceros ( Stummer-Traunfels 1933, p. 3487 and fig. 95 ) He stated a distinction between P. striatus sensu Schmarda (1859, p. 27 and fig. 62) and sensu Keelart (1858, p. 137; Keelart in Collingwood 1876 , p. 97 and fig. 25), since one is described as white with dark stripes and the other as dark with bright stripes. Hyman (1959a) solved the confusion stating P. gratus ( Kato 1937 ) is synonymous to the original Schmarda species and thus there was no need for the new name given by Marcus. Faubel (1984) followed Marcus’ opinion, while Newman & Cannon (1994) followed Hyman. We find that Hyman (1959) is right and Pseudobiceros gratus has priority over P. strigosus . However, Pseudobiceros strigosus is still the name of the genus type . There is only observation that must be done to Newman & Cannon (1994) , Pseudoceros habroptilus ( Hyman 1959 ) should not be included in Pseudobiceros gratus synonym list, as it was described without information about reproductive structures, and it was draw with two median lines instead of one, as present in Pseudobiceros gratus .
