Cribellopora hluchovensis View in CoL sp. n.
Pl. 121, Fig.1-4
D i a g n o s i s: Colony encrusting. Autozooecia hexagonal or oval with small frontal pores. Lateral walls distinct. Aperture oval to circular with a wide sinus, no oral spines. Ovicell flat with a smooth, nonporous frontal wall.
H o l o t y p e: The specimen illustrated on Pl. 121, Fig. 1-3 from the section Hluchov, deposited in the NM Prague under the number PM2-P 01504
P a r a t y p e s: Four specimens from the section Hluchov deposited in the NM Prague under the numbers PM2 - P 01506 – P 01507
D e r i v a t i o n o m i n i s: Due to the occurrence in the section at Hluchov.
L o c u s t y p i c u s: Hluchov
S t r a t u m t y p i c u m: Langhian – Lower Badenian.
M e a s u r e m e n t s: (in micro meters = µm; x = = average)
length of autozooecia: 466-739; x = 566
width of autozooecia: 307-545; x = 406
length of autozooecial aperture: 107-169; x = 133
width of autozooecial aperture: 106-157; x = 125
length of ovicell: 277-393; x = 324
width of ovicell: 321-391; x = 358
D e s c r i p t i o n: Colony encrusting, usually covering large areas on bivalve fragments. Autozooecia regularly hexagonal or oval, slightly longer than wide, separated by deep furrows. Frontal wall convex, smooth, slightly perforated by frontal pores. Lateral walls narrow, distinct, visible mostly on the proximal half of the autozooecia, sometimes around the whole autozooecia, inside the furrows. Aperture oval to circular with a wide sinus. No oral spines observed. Ovicell flat, deeply immersed into the distal part of the autozooecium with a smooth, nonporous frontal wall. The marginal pores on the ovicell are not clearly visible due to preservation, but probably do exist.
C o m p a r i s o n: Differs from Cribellopora latigastra ( DAVID, 1949) in having small frontal pores, distinct lateral walls and a narrower sinus. The shape of the frontal pores is not visible due to preservation. It differs from Cribellopora trasoni sp. n. in having a wide sinus and smaller frontal pores.
R e m a r k: Due to the presence of frontal pores, rows of marginal pores on the ovicell and a broad sinus this
158 species belongs to Cribellopora as described by Gordon (1984).
O c c u r r e n c e: Only in the section at Hluchov.
