Type Species

A. michelinii Milne Edwards and Haime, 1848, p.320, pl. 7, fig. 5, 5a; Monotypy

Type Specimen: Neotype; USNM 80350; Verified; Dry Preserved

Type Locality: Recent: off Atlantic City, New Jersey

Original type lost (see Chevalier, 1966); neotype designated by Peters, et al., 1988, the same specimen also serving as the neotype of Madrepora poculata, making these two species objective synonyms. Type species also well described and illustrated by Peters, et al. (1988). A. michelinii Milne Edwards and Haime, 1848:320, pl. 7, fig. 5, 5a [=Astrangia poculata (Ellis and Solander, 1786)]




Corallum colonial, usually encrusting or subplocoid in calice arrangement achieved by extracalicular budding from edge zone; corallites united basally by thin coenosteum; costae granular; axial edges of all septa dentate; columella papillose.


Differs from Hoplangia in having entire axial edges of septa dentate.


The genus is in need of revision. There are approximately 30 species, 15 of which occur in the Recent (Cairns et al., 1999).
