Abstract

The tabulate coral Pleurodictyum bifidum Jones, 1944, from the Early Devonian (Pragian or lower Emsian) Garra Formation of central New South Wales, Australia is revised on the basis of the holotype and three other specimens. It is selected as the type species of the new monotypic genus Bifidomeria (Family Roemeriidae), which differs from Roemeria in its strictly cerioid corallum, its bifid septal spines and aspects of its microstructure. Study of the detailed microstructure of two other tabulate corals from the Devonian of New South Wales has led to the following revised generic assignments: Michelinia progenitor Chapman, 1921, previously assigned to Roemeripora, is assigned to Roemeria, and Holacanthopora clarkei Wright & Flory, 1980 is assigned to Michelinia.
