holotype
, Capron Shoal, near Buoy 10 A, off South Hutchinson Island, St. Lucie Co., Florida,

Description.
Colonies (
Fig. 14
A) encrusting, biserial to multiserial on calcareous substrata ranging from very small sand-size grains to shells and
Oculina
branches. Zooids ovoid, boundaries marked by deep grooves (
Fig. 14
B, C). Orifice semicircular with 5, thick, distal spines around autozooid rims and 4 spines on ovicelled zooids. Frontal shield formed by 10–15 fused costae, with radiating rows of intercostal lacunae in between; outer edges of costae thickened and raised into tubercles, giving zooids a thick-rimmed appearance. A larger suboral foramen proximal to orifice, the first pair of costae forming a raised V below it. Ooecium helmet shaped, imperforate, with raised central keel (
Fig. 14
B, C). No avicularia. Ancestrula tatiform, with 9–11 spines (14D). Sexual reproduction may occur within five generations of ancestrula.
Distribution.
East coast of Florida.
