sensu Kozur & Mostler (1989)

Scharfenbergia Won, 1983: 158 . — Kozur & Mostler 1989: 220.

TYPE SPECIES. — Spongotripus concentricus Rüst, 1892 ( Rüst 1892: 173, pl. 25, fig. 4).

AGE AND LOCATION OF TYPE MATERIAL. — Lower Carboniferous, Rheinischen Schiefergebirge, Germany.

TAXON CODE. — 215.

STATUS. —Homonym; replacement name is Wonia Özdikmen,2009 .

DIAGNOSIS. — “Das Skelett ist im Habitus triangular bis dreiarmig und besteht aus spongiösem Geflecht. Dieses kann sowohl individuell als auch interspezifisch unterschiedlich stark entwickelt sein. Durch Verdickung ist es bei einigen Arten säulenartig ausgebildet. Im Innern des Skeletts liegt eine sphäroidale Zentralschale. 3 von ihr ausgehende axiale Stäbe sind mit dem umgebenden Gewebe verbunden und können sich in distaler Richtung verdicken. Sie sind an den Ecken des Skeletts bzw. an den Enden der Arme als kurze Stacheln sichtbar.” ( Won 1983: 158).

DIAGNOSIS (English translation by J. P. Caulet RadWorld – database). — “Triangular to three-armed spongy test. Various shapes between triangular and three-arms can be observed at individual, or intraspecific, level. Some species can be column-shaped through thickening of the test. Spherical central shell inside the test. Three axial rods link the internal shell to the surrounding framework and can thicken in distal direction. They are visible as short spines at the corners of the test, i.e. the ends of the arms.”

REMARKS

There is considerable taxonomic overlap between the original diagnoses proposed for this genus by Won (1983) and and Latentifistula Nazarov & Ormiston, 1983 , but since their original publication, revisions to both genera have alleviated the problem. Subsequent usage of Scharfenbergia , as proposed by Kozur & Mostler (1989) and discussed in Nestell & Nestell (2010), restricts Scharfenbergia to the triangular forms similar to the Mississippian age holotype. Meanwhile, Latentifistula includes triradiate or trilobate species that Won (1983) had assigned to Scharfenbergia , including Paronaella impella Ormiston & Lane, 1976 . Scharfenbergia is the junior homonym to the arthropod Scharfenbergia Oudemans, 1936 . As Scharfenbergia is preoccupied the replacement name Wonia was proposed by Özdikmen (2009).
