Melnikova, 1975: 99

Type Species
Isastraea profunda Reuss in Melnikova 1975:101; Original Designation Melnikova 1975:101
Type Specimen: Neotype; NHMW 1851 XII 1898; Not Traced; Dry Preserved
Classification

Diagnosis
Cerioid. Increase by division of corallite; dividing wall founded on opposing septa. Septal sides with protruding, flat granules. Endotheca dissepimental. Wall formed of a straight or zigzag row of vertical trabeculae; septal trabeculae connect with the row of wall trabeculae.
Description
Microstructure of the type species was described in detail by Cuif 1976:113,text-fig.12,pl.11:1-6. Additional detailed descriptions are in Roniewicz 1989:33,pl.4,fig.1,pl.5, fig.3. Microstructure of other species was described in Cuif 1976: 114, and 138,text-fig.13,21, pl.14,fig.5, and in Roniewicz 1989:32, pl. 4, fig. 2-4, pl.5, fig. 1,2. Melnikova's material origin form the late Norian of the SE Pamirs.
Comparisons
Characteristic microstructure of wall, made of trabeculae ordered in a pallisaded manner, and its relations with that of septa is the feature differentiating this genus from other cerioid corals.
Remarks
Five species are known.
