Anthemiphyllia frustum, sp. nov

DESCRIPTION.—Corallum tympanoid or frustum-shaped, with a flat base and a low, slightly inwardly curved theca resulting in a basal diameter slightly larger than that of calice. Holotype 9.94 mm in basal diameter, 8.96 mm in calicular diameter, and 4.71 mm in height. Costae equal in width (0.5–0.7 mm at edge of base), relatively flat, and separated by quite narrow (0.02–0.05 mm), shallow intercostal striae. Costae finely granular, 5 or 6 small (0.05 mm in diameter) rounded granules occurring across the width of a costae near corallum edge. Corallum white or reddish brown.

Septa hexamerally arranged in 4 complete cycles (48 septa) in all specimens examined. S1 bear 5 or 6 massive triangular teeth, each tooth up to 1 mm in height and 0.9 mm in width, the innermost tooth being directly adjacent to columella. S2 similar to S1 in construction, but their teeth not quite as tall. Both S1 and S2 quite robust and closely spaced, measuring about 0.5 mm in thickness at calicular edge and separated by only about 0.1 mm. S3 support 4 or 5 tall, triangular teeth, each tooth up to 0.5 mm wide, but not quite as tall as those of the S1–2. S4 bear 5 or 6 triangular teeth, which decrease in width toward columella. S3–4 about 0.35 mm in thickness. Each pair of S4 within a half-system unites before its adjacent S3 near the columella in a common triangular septal tooth about 0.2 mm wide. Orientation of faces of septal teeth is parallel to that of septal faces. All septal faces coarsely granular, except for tips of large septal teeth, which are smooth. Columella papillose, composed of 10–15 massive, rounded, finely granular papillae.
