Description Original description of the type species by Ogilvie 1897, and description by Geyer 1955: 188, pl. 26, fig. 9 point to cerioid type of colony and presence of dissepimentarium. But the illustration accompanying Geyer's description presents a specimen housed at the Geologisches Institut TH Stuttgart, not the holotype housed at the Bayerisches Staatssammlung München, and shows features different form those in generic diagnosis and observed in figures of Aulastrea conferta in Ogilvie 1897.The topotype specimen of Eliášová 1975: text fig.4, pl. 4 fig. 1, 2 from the Štramberk quarry, examined in thin sections and well illustrated, suits to the original description. A. conferta from the lower Aptian in the Alps, ("Schrattenkalk"), was described in Baron-Szabo (1997: 73). [details]

Comparison From cerioid Pleurostylina de Fromentel, 1856 and Amphiastrea Etallon, 1859 differs in having wide dissepimentarium made of large-vesiculae. [details]Description Original description of the type species by Ogilvie 1897, and description by Geyer 1955: 188, pl. 26, fig. 9 point to cerioid type of colony and presence of dissepimentarium. But the illustration accompanying Geyer's description presents a specimen housed at the Geologisches Institut TH Stuttgart, not the holotype housed at the Bayerisches Staatssammlung München, and shows features different form those in generic diagnosis and observed in figures of Aulastrea conferta in Ogilvie 1897.The topotype specimen of Eliášová 1975: text fig.4, pl. 4 fig. 1, 2 from the Štramberk quarry, examined in thin sections and well illustrated, suits to the original description.

Diagnosis Cerioid, with a mid-line in the intercorallite wall, corallites polygonal, irregular in shape. Calices infundibuliform, with peripheral, large-vesicular dissepimentarium and internal part containing septal apparatus limited by internal wall. Septa numerous, differentiated into four size orders and distributed in radial-bilateral symmetry: the S1 septa thicker than others, with columellar septum the strongest; the S2 septa shorter; the S3 septa usually regularly distributed, the S4 septa appearing at least in the sectors near the columellar septum. Inside the space limited by internal wall, endotheca is made of tabuloid elements. Internal wall is similar in structure to the external pachythecal wall. Pachythecal external wall is thick. Increase by Taschenknospung. [details]
Remark Six species are known from the Tithonian and Lower Cretaceous. The genus is expected among corals described from the Lower Cretaceous as Amphiastraea by Prever (1909) and Eguchi (1951). [details]
