Fourteen of the 19 recorded species of neotropical Temnocephala are re-examined for new taxonomic characters and all records are tabulated. Autapomorphies found are eyespots with red, fugacious pigment, a characteristic pattern of syncytial epidermal plates and excretory pores enclosed within the boundaries of the paired post tentacular ('excretory') plates. The worms are rather homogeneous with regard to the genital structures (although T. brenesi has only one pair of testes) and appear to hold their tentacles in a consistent pattern. This suite of species is homogeneous, differing from worms from Australia currently assigned to the genus. Since the type of the taxon Temnocephalida, Temnocephala chilensis (Moquin-Tandon, 1846), has the suite of characters shown here, a new genus (Temnosewellia gen. nov.) is proposed to accommodate Australian representatives formerly in Temnocephala.
