Genus Puellina JULLIEN, 1886 View in CoL

Colony encrusting. Autozooecia oval with a costal frontal wall and with lateral costal fusions forming intercostal pores. Gymnocyst reduced or absent. Orifice semilunar with calcified margins, suboral lacuna and oral spines. Interzooecial avicularia present. Ovicell partly immersed with nonporous frontal wall.

? Puellina (Cribrilaria) venusta ( CANU et BASSLER, 1925) View in CoL – Schmid p. 28, Pl. 7, Fig. 1-5 (cum syn.)

M a t e r i a l: Altogether 18 specimens were studied from different sections.

D i a g n o s i s: Frontal shield formed by 11-13 costae with 4 to 5 intercostal pores. Oral spines large, usually 5-6 around each aperture, ovicelled autozooecia always developing 4 oral spines. Avicularia drop-like, half the length of autozooecia with a wide gymnocyst and a palate usually tapering distally. Ovicell deeply immersed with a medial keel and a nonporous frontal wall.

R e m a r k s: Differs from the more common Puellina (Cribrilaria) scripta ( REUSS, 1847) in having more costae (about 16) and larger avicularia with a large palate tapering usually laterally.

Schmid (1989) discussed in detail the taxonomy of this species and replaced the more common designation as Cribrilaria radiata ( MOLL, 1803) , by Puellina venusta . Cribrilaria radiata is usually used for recent specimens.

1977 Cribrilaria rarecostata (REUSS) – Vávra p. 102 (cum. syn.)

T y p e: No lectotype was established, there are two ‘syntypes’ redescribed by David and Pouyet (1974) stored in the Natural History Museum Vienna under the number 1847.38.76 .

M a t e r i a l: Altogether 2 colonies were studied from the section Podbřežice.

D i a g n o s i s: Colony encrusting, autozooecia oval to hexagonal with semilunar orifice and five oral spines. Frontal shield consists of 6 to 8 costae. No avicularia developed, ancestrula circular with 4 oral spines. Ovicell small, smooth.

R e m a r k s: Number of costae and oral spines are identical with the type material. According to Bock (2010), the subgenus Cribrilaria CANU et BASSLER, 1929 may be treated as a subgenus of Puellina , and therefore this species is listed here within Puellina .
