Diagnosis
Colonial, massive, meandroid. Gemmation intracalicinal. Calicinal series forked, generally united by peritheca or exotheca. Ambulacrae present, narrow. Costosepta compact, non-confluent, laterally granulate and carinate. Columella lamellar, discontinuous. Endothecal dissepiments abundant. No synapticulae. Wall parathecal to septoparathecal.
Remarks
In having thick, compact costosepta and a well-developed exothecal wall, the material figured from the Aptian of Uzbekistan as Astrogyra edwardsi (Reuss, 1854) in Kuzmicheva (1982) rather corresponds to the genus Stiboriopsis Vaughan, 1899.
