AB  - There has been confusion regarding the delineation of genera in the Flabelligeridae. Thus, it is not surprising that some genera like <i>Pherusa</i> Oken, 1807 currently include different body patterns with differing branchial and chaetal features. A revision of all materials available has allowed a standardized approach; one of its results has been the restriction of <i>Pherusa</i> to encompass species provided with eight branchial filaments and anchylosed neurochaetae. At the same time, <i>Stylarioides</i> delle Chiaje, 1831, with <i>Stylarioides monilifer</i> delle Chiaje, 1831, as its type species, which has been wrongly regarded as a junior synonym of other flabelligerid genera, is reinstated, restricted and revised. It includes species whose members have cylindrical bodies, often tapering into a distinct, thinner cauda, and their tunic includes a variable amount of sediment grains on their papillae. The branchiae are arranged in two lateral spirals, often transformed into a serpuloid branchia by having two lateral branchial peduncles, each with filaments arranged in spiral; the body papillae are short, and their chaetae include fine, short, multiarticulate notochaetae, and short, anchylosed neurohooks. <i>Coppingeria</i> Haswell, 1892, a monotypic genus defined by the presence of two branchial peduncles with spiral filaments, is regarded as a junior synonym of <i>Stylarioides</i>. The species included are <i>S. monilifer</i> from the Mediterranean Sea, <i>S. bengalensis</i> Fauvel, 1932, from India, <i>S. granulosus</i> Caullery, 1944, from the Java Sea, <i>S. grubei</i> n. sp. from the Red Sea, <i>S. hirsutus</i> Lo Bianco, 1893, from the Mediterranean Sea, <i>S. longisetosa</i> (Haswell, 1892) n. comb., from Australia, <i>S. muiri</i> n. sp. from Tristan da Cunha, <i>S. plantei</i> n. sp. from Madagascar, <i>S. saldanha</i> (Day, 1961) n. comb., from South Africa, <i>S. swakopianus</i> Augener, 1918, from Western Africa, and <i>S. tropicus</i> Augener, 1918, from Western Africa. Other species provided with lateral pedunculate branchiae differ from <i>Stylarioides</i> by having a racket-shaped peduncle, where the thin branchial filaments are separated into two lateral groups, each with filaments arranged in parallel lines. Further, their body has a truncate posterior end, larger cephalic cage chaetae, and larger notochaetae and neurohooks. For these species, <i>Treadwellius</i> n. gen. is proposed, with <i>Stylarioides atentacula</i> Hoagland, 1920, as the type species. The species included are <i>T. atentacula</i> (Hoagland, 1920) n. comb, from the Philippine Islands, <i>T. bifidus</i> (Fauvel, 1932), from the Arabian Sea, and <i>T. gilleti</i> n. sp. from Western Africa.
