Characters: Colonies are branching, branches approximately 15 mm across, indeterminate, curved and tapered. Axial corallites are prominent, tubular, 3-4 mm diameter. Incipient axial corallites are common. Radial corallites are of mixed sizes, with projecting lower lips. Septa are thick and fused into a poritid septal pattern with fused or partly fused lateral pairs and with a dorsal and ventral directive. Columellae are present and fused with the dorsal directive and often other septa. The calice wall forms a slightly raised ring. Known from a single specimen.
Colour: Brown.
Similar Species: Almost indistinguishable from finely branched Acropora aspera except for the corallite structure which is not found in any other coral. Also very similar to A. pulchra.
Habitat: Collected from 2m depth in a turbid environment.
Abundance: Presumably rare but may have been overlooked due to close similarity to Acropora species.
Taxonomic Note: The type species of Enigmopora Ditlev, 2003 is similar to Acropora but, unlike all Acropora and Isopora has some corallites with solid septa reaching a solid columella. Like most Acropora there are dorsal and ventral directive septa and lateral septa that may be arranged in Porites-like pairs. We have re-examined the type material and believe that further work involving more specimens is needed to be confident that this a species rather than an abnormality, as is common in corals.
