Description:
<p>A new genus of flabellid scleractinian coral, <italic>Periplacotrochus</italic>, is described from the late Eocene to middle Miocene of Victoria, South Australia, and Tasmania. It differs from <italic>Placotrochus</italic> in having a pedicellate base, and from <italic>Flabellum</italic> in having a lamellar columella. Six previously described species are redescribed, illustrated, and reassigned to this genus (<italic>P. deltoideus</italic> Duncan, 1864, <italic>P. corniculatus</italic> Dennant, 1899, <italic>P. elongatus</italic> Duncan, 1864, <italic>P. pueblensis</italic> Dennant, 1903, <italic>P. inflectus</italic> Dennant, 1903, and <italic>P. magnus</italic> Dennant, 1904), and one new species is described: <italic>P. cudmorei</italic>. One species, <italic>Placotrochus elegans</italic> Tennison-Woods, 1878a, is considered as a nomen dubium. A key is provided to the seven species placed in this genus.</p>
