All three were examined with light and scanning electron microscopy. The unique combination of morphological features in one of the new species prompted formal investigation of the non-monophyly of\n                    <jats:italic>Paraorygmatobothrium<\/jats:italic>\n                    relative to the morphologically similar genera\n                    <jats:italic>Doliobothrium<\/jats:italic>\n                    ,\n                    <jats:italic>Guidus<\/jats:italic>\n                    ,\n                    <jats:italic>Marsupiobothrium<\/jats:italic>\n                    ,\n                    <jats:italic>Nandocestus<\/jats:italic>\n                    ,\n                    <jats:italic>Orectolobicestus<\/jats:italic>\n                    ,\n                    <jats:italic>Ruhnkecestus<\/jats:italic>\n                    and\n                    <jats:italic>Scyphophyllidium<\/jats:italic>\n                    . Sequence data generated for part of the 28S rDNA gene were subjected to maximum likelihood (ML) analysis. The resulting tree led to the synonymization of six of these seven genera with\n                    <jats:italic>Scyphophyllidium<\/jats:italic>\n                    , and transfer of their species to the latter genus. With the new species, the number of described members of\n                    <jats:italic>Scyphophyllidium<\/jats:italic>\n                    is now 45. The diagnosis of\n                    <jats:italic>Scyphophyllidium<\/jats:italic>\n                    is revised to accommodate these species. In addition, to expedite future descriptions, eight categories of\n                    <jats:italic>Scyphophyllidium<\/jats:italic>\n                    species are circumscribed, based largely on bothridial features.\n                    <jats:italic>Scyphophyllidium timvickiorum<\/jats:italic>\n                    n. sp. is a category 1 species. Beyond being the smallest category 1 species, it bears, rather than lacks, apical suckers and lacks, rather than bears, strobilar scutes. The two other new species are members of\n                    <jats:italic>Clistobothrium<\/jats:italic>\n                    .\n                    <jats:italic>Clistobothrium amyae<\/jats:italic>\n                    n. sp. differs from its congeners in bothridial shape, elongate cephalic peduncle and tiny size.\n                    <jats:italic>Clistobothrium gabywalterorum<\/jats:italic>\n                    n. sp. differs from the two of its congeners that also possess foliose bothridia in overall size and testis number. Despite their substantial morphological differences, the ML tree indicates they are sister taxa. Both are unique among their congeners in possessing cephalic peduncle spinitriches.
