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 periculosus Newman & Cannon, 1994 Taxonomic remarks. The species belongs to a color group showing a dark background and orange to yellow margin that should be thoroughly revised. Prudhoe (1977) reported from Queensland a species with two male gonopores which he misidentified as Pseudoceros flavomarginatus . This species was listed under single male gonopore Pseudoceros species ( Laidlaw 1902, p. 297 and 298 ), but Prudhoe’s specimen belongs to a darkbackground Pseudobiceros . The description by Prudhoe fits the species Pseudobiceros periculosus ( Newman & Cannon 1994 ) in marginal and background color, elongated cerebral eyespots group, and geographical proximity.
