Genus Asterosmilia Duncan, 1867 View in CoL

(= Sphenotrochopsis Alloiteau & Tissier, 1958 , Type species. Sphenotrochopsis alloiteaui Alloiteau & Tissier, 1958 , Paleocene of France)

Type species. Trochocyathus abnormalis Duncan, 1863 View in CoL , Miocene of the West-Indies (subsequent designation Vaughan, 1919).

Diagnosis. Solitary, trochoid-ceratoid, generally free. Costosepta compact, minutely and densely granulated laterally. Costae prominent or flat. Pali or paliform lobes next to last one or two cycles, usually opposite S3. Columella lamellar at surface, trabecular below. Wall septothecal to septoparathecal. Epithecal wall pellicular when present.

Remarks. Alloiteau & Tissier (1958) described the genus Sphenotrochopsis from the Upper Danian of Belgium. According to the authors, the genus is characterized by a trabecular columella that appears lamellar, compact costosepta that are finely and densely granulated laterally, paliform structures that occur before oldest cycle septa (for the species Sphenotrochopsis alloiteaui that means before the cycles next to last one or two cycles), and a septothecal wall (parathecal only at very top of corallum). Synonymy of Sphenotrochopsis with Asterosmilia is therefore indicated.
