Diagnosis
Reference | Diagnosis | |
---|---|---|
D. Huang et al. 2014 | Colonial, with intracalicular budding only. Corallites monomorphic and discrete (one to three centres); monticules absent. Coenosteum costate, moderate amount (< corallite diameter), limited (includes double wall) in some species. Generally, calice width medium
(4–15 mm), with medium relief (3–6 mm); few species with wider and/or deeper calice. Costosepta not confluent. Septa in three cycles (24–36 septa). Free septa present but generally irregular (regular in Dipsastraea helianthoides and Dipsastraea laxa). Septa spaced six to 11 septa per 5 mm. Costosepta equal in relative thickness. Columellae trabecular and spongy (> three threads), < 1/4 of calice width, and continuous amongst adjacent corallites. Paliform (uniaxial) lobes weak or moderate. Epitheca well developed and endotheca low−moderate (tabular). Tooth base at midcalice circular. Tooth tip at midcalice irregular; tip orientation perpendicular to septum. Tooth height medium (0.3–0.6 mm) and tooth spacing medium (0.3–1 mm), with > six teeth per septum. Granules scattered on septal face; irregular in shape. Interarea palisade. Walls formed by dominant paratheca and partial septotheca; abortive septa absent. Thickening deposits fibrous. Costa centre clusters generally strong but highly variable; 0.3–0.6 mm between clusters; medial lines weak. Septum centre clusters weak; 0.3–0.5 mm between clusters; medial lines weak. Transverse crosses present. Columella centres clustered. |
