Cryptocoenia Orbigny, 1849, p. 7 is a junior synonym (available and invalid), see Cyathophora Michelin, 1843, p. 104.
Type Species
Astrea alveolata Goldfuss, 1826, p. 65, fig. 3a,b; Monotypy
Type Specimen: Syntype; IPB 217; Verified; Dry Preserved
Type Locality: Malm, Heidenheim (Germany)
The type species of Cryptocoenia was described in D’Orbigny, 1850 in brief with six septa and radial symmetry. Alloiteau 1948b, considered Cryptocoenia as the synonym of Cyathophora but he was not followed by most of subsequent authors. Geyer, 1954 considered that the fig 3b in Goldfuss which is a detail figure of 3a does not correspond to the same species. Löser 1994 and 1998 used Cryptocoenia in place ofCyathophora because the figured type specimen of the latter genus was lost at this time. Finally this genus was illustrated in Zaman (2012) where the synonymy between Cyathophora and Cryptocoenia is confirmed.
