Pseudobiceros undulatus ( Kelaart, 1858)

Taxonomic remarks. The species was originally described as Planaria undulata ( Kelaart 1858) and synonymized with Schmarda’s (1859) Eurylepta suberba and later mentions in different genera (Diesing 1962, Stummer- Traunfels 1933), by Marcus (1950). Stummer-Traunfels (1933) illustrated the species having two male gonopores, thus it was transferred to Pseudobiceros by Faubel (1984). There is, however, a disparity in the drawings presented by Schmarda (1859), without a clear purplish median line, and Collingwood (1876), with the median line. This species should be further studied with the examination of fresh specimens as to solve if there is such color plasticity. It is unclear why this species was left out by Newman & Cannon (1994, 1997).
