In earlier literature described as Volzeia (Hexastraea) fritschi (Volz 1896) in Cuif 1974: 352-354, figs 25 and 26.
Paravolzeia alpina Roniewicz et al. 2005, p. 293, fig. 44D, G.; Original Designation Roniewicz, et al. 2005, p. 293
Type Specimen: Holotype; ZPAL HVIII/1; Verified; Dry Preserved
Type Locality: Dolomites, Southern Alps, Carnian, LateTriassic
Phaceloid. Corallites of 3-5 mm in diameter with ca. 24 septa of the S1-S3 orders and septa S4 hidden in the wall. Increase by septal division (from bi- to quadruple division). Costosepta exsert, differentiated into at most four size orders, their faces smooth. Costal part embedded in the epithecal wall. Endotheca tabular.
Up to now, two species, both from the Carnian, have been described: the type species, P alpina from the Alps, and P. timorica from the eastern part of Timor (Timor -Leste), smaller in corallite diameters and number of septa from the type species. The type material of P. timorica, under the number of H1219, is housed in the Department of Geology, University of Auckland, Auckland, New Zealand.
Cuif 1974: 352-353 gave interesting observations and perfect illustrations in figs 25 and 26, presenting coral microstructure, with its erroneous determination, as Volzeia fritschi (Volz). The latter species represents Quenstedtiphyllia fritschi, the earliest known up to now amphiastraeid coral.
