Genus Pseudofavia Oppenheim, 1930

TYPE SPECIES. — Parastrea grandiflora Reuss, 1854 by monotypy.

DIAGNOSIS. — Astreoid colony. Calicular outline polygonal to circular. Calices large. Calicular centres slightly depressed, margins elevated. Radial elements irregularly perforated. Microstructure of large trabeculae. Radial elements in cross-section externally thick, becoming thinner towards the centre. Symmetry of radial elements irregularly radial. Cycles of radial elements subregular. Septal generations differ in length and thickness. First septal generation reaches to the centre of the calice, further generations are subsequently shorter. Radial elements occasionally connected to each other, upper border with large regular granules. Septal lateral face with thick granulae, inner margin smooth. Some radial elements may be attached to the columella. Costae present, nonconfluent. Synapticulae present, abundant. Columella small, substyliform. Endotheca consists of numerous dissepiments. Wall absent. Coenosteum very narrow, consisting of large trabeculae. Budding extracalicinal.

RANGE. — Late Turonian to Santonian. The genus does not occur in the Early Cretaceous or Cenomanian. The first occurrence is not well constrained (Turonian of Italy).

DISTRIBUTION. — Western and central Tethys.

SPECIES

Two species:the type species and Pseudofavia paronai (Zuffardi-Comerci, 1930) . Pseudofavia andrusovi Kühn in Kühn & Andrusov, 1930 belongs to Paraplacocoenia . Pseudofavia mariae Reig Oriol, 1997 has thin compact radial elements and does not belong to this genus. Synastrea adkinsi Wells, 1934 and related material probably belong to Pseudofavia or to a new, as yet undescribed, genus.

REMARKS

Pseudofavia is not a nomen novum for Parastraea Reuss non Milne Edwards & Haime as stated by Wells (1956: 388). Reuss never described such a genus. Oppenheim (1930) said it could be a nomen novum for Parastraea Felix, 1903 , but Felix (1903) never established such a genus. Felix himself referred clearly to Reuss, who has (see above) never established such a genus. Cretastraea Kühn & Andrusov, 1930 is a junior objective synonym.
