Family Lepraliellidae VIGNEAUX, 1949 Genus Celleporaria LAMOUROUX, 1821

Colony encrusting, multilaminar, massive. Autozooecia erect with marginal areolar pores only. Primary aperture

144 without sinus, but often with condyles. Oral spines often present. Avicularia suboral and/or vicarious. Ovicell slightly immersed, with imperforate frontal wall.

v. * 1874 Lepralia cornigera m. – Reuss p. 157, Pl. 7, Fig. 11

v. 1977 Celleporaria cornigera ( REUSS, 1874) – Vávra p. 154 (cum syn.)

T y p e: Holotype stored in the Natural History Museum Vienna under the number 1878.11.30.

M a t e r i a l: Altogether 7 specimens were studied mainly from the section Podbřežice.

D i a g n o s i s: Colony small, globular. Autozooecia erect, their shape hidden by frontal budding, areolar marginal pores very large. Primary aperture with straight proximal margin, no condyles visible. One suboral avicularium situated on a small umbo. Vicarious avicularia with pivotal bar, ligula lacking. Ovicell not visible on studied material.

R e m a r k s: The straight proximal margin of the primary aperture is very characteristic and together with the absence of condyles it clearly enables identification of this species.

Celleporaria palmata ( MICHELIN, 1847) View in CoL – Moissette p. 184, Pl. 29, Fig. 4-8 (cum syn.)

M a t e r i a l: Altogether 4 specimens were studied, but perhaps even more, but due to the preservation, no exact determination was possible.

D i a g n o s i s: Colony small, globular. Autozooecia erect, the shape hidden by frontal budding, areolar marginal pores clearly visible. Primary aperture with a pair of condyles and a narrow lyrula. One suboral avicularium situated on a small umbo. Ovicell not found in the studied material.

R e m a r k s: Celleporaria palmata ( MICHELIN, 1847) as re-described by Pouyet (1973) shows an identical development of the primary aperture and suboral avicularia.

v. 2004 Cellepora polythele REUSS, 1847 – Vávra p. 26, Fig. 1 (cum syn.)

T y p e: Lectotypes stored in the Natural History Museum Vienna under the number 1859.45.657 ( Vávra, 2004) .

M a t e r i a l: Altogether 10 specimens were studied, mainly from the section Hlohovec and 2 samples from Vávra’s collection stored in the Department of Palaeontology, Geozentrum (University of Vienna). An additional 5 specimens from the Reuss collection stored in the Natural History Museum Vienna under the numbers 1859.45.653, 1859.45.658, 1847.37.232, 1846.37.999 and 1867.11.144 from the section Hlohovec have also been investigated .

D i a g n o s i s: Coloniesglobular with prominent protuberances. Autozooecia indistinct, their shape hidden due to the frontal budding, marginal areolar pores only. Primary aperture without sinus, condyles very small. Suboral avicularium small. Vicarious avicularia were described by Vávra (2004), but not observed in the studied material. Ovicell globular, imperforate.

R e m a r k s: Although Vávra (2004) did not resolve the problem of generic attribution of this species, the clear absence of a sinus, the small condyles and the imperforate frontal wall of the ovicell clearly characterize the genus Celleporaria . The characteristic protuberances of this species are visible with the naked eye.

A detailed description and re-description is given by Vávra (2004).
