Genus Lunaferamita Utgaard, 1981

TYPE SPECIES. — Fistulipora? bassleri Loeblich, 1942 by subsequent designation ( Utgaard 1981), Bromide Formation, lower Sandbian, Upper Ordovician, Oklahoma, United States.

DIAGNOSIS. — Colonies encrusting or ramose. Indistinctly stellate monticules with large, irregular vesicles forming subcircular to elongate centre and radiating inter-rays of vesicles separating rows of loosely aggregated autozooecia. Lunaria on proximal sides of autozooecia nearest the centres of monticules. Autozooecia with thin, transversely laminated walls and many, closely spaced to few, remote diaphragms; isolated by box-like to blister-like vesicles. Acanthostyles few to abundant within laminated vesicle walls or roofs. Lunaria laminated, commonly with hyaline core.

OCCURRENCE. — Lunaferamita bassleri ( Loeblich, 1942) , L. nevadensis Utgaard, 1981 , and L. virginiensis Utgaard, 1981 were reported from the Sandbian of United States. Lunaferamita nevadensis Utgaard, 1981 and L. vesicularis Chang, Yang & Xigiang, 2011 were reported from the Lianglitag Formation (Upper Ordovician, Katian) of China (Tarym).

COMPARISON

Lunaferamita differs from Constellaria Dana, 1846 by having lunaria and monticules of indistinct stellate shape. Furthermore, Lunaferamita possesses vesicles in endozones.
