Fistulipora arauzensis n. sp. ( Figs 7E, F View FIG ; 8 View FIG A-E; Appendix)
HOLOTYPE. — SMF 21.165 View Materials .
PARATYPES. — SMF 21.166- SMF 21.191.
ETYMOLOGY. — The species name refers to Arauz Sur, the locality where the new species was found.
TYPE LOCALITY. — Arauz Sur (Arroyo section), Province of Palencia, NW-Spain (Cantabrian Mountains).
TYPE HORIZON. — Lebanza Formation, Lower Devonian (Pragian).
DIAGNOSIS. — Encrusting colonies with multilayered secondary overgrowths; autozooecial diaphragms few to absent, thin, planar or concave; autozooecial apertures rounded; lunaria small; vesicles abundant both in endozone and exozone, moderately large, completely isolating autozooecia in 1-2 rows, 6-12 surrounding each autozooecial aperture; maculae small, slightly depressed, consisting of vesicular skeleton, spaced widely on the colony surface.
DESCRIPTION
Encrusting colonies with multilayered secondary overgrowths. Multilayered colonies up to 4.8 mm
thick, separate sheets 0.9-3.5mm thick. Autozooecia growing from laminated basal layer. Autozooecial diaphragms few to absent, thin, planar or concave. Autozooecial apertures rounded. Lunaria small, horseshoe-shaped, directed to the nearest macula, consisting of hyaline material. Vesicles abundant both in endozone and exozone, moderately large, box-like, polygonal in tangential section, having flattened roofs, completely isolating autozooecia in 1-2 rows, 6-12 surrounding each autozooecial aperture; in endozone usually higher than those in exozone. Moderately thick layer of granular skeleton on colony surface often developed.Autozooecial walls thick, granular. Maculae small, slightly depressed, consisting of vesicular skeleton, 0.05-0.06 mm in diameter, spaced widely on the colony surface.
COMPARISON
Fistulipora arauzensis n.sp. is similar to F. compacta Astrova, 1964 from the Lower Devonian (Lochkovian) of Ukraine. The new species differs in having larger vesicles (vesicle diameter 0.07-0.018 vs 0.04-0.12 mm in F. compacta ) and wider spaced autozooecia. Fistulipora arauzensis is also similar to F. trifoliata Schlütter, 1889 from the Middle Devonian of the Eifel but differs from it in having smaller lunaria and larger autozooecial apertures (0.14-0.24 vs 0.12-0.20 mm in F. trifoliata ).
