Pseudolithelius Kozur & Mostler, 1989

Pseudolithelius Kozur & Mostler, 1989: 185 .

TYPE SPECIES. — Pseudolithelius permicus Kozur & Mostler, 1989 ( Kozur & Mostler 1989: 186, pl. 17, fig. 1, 4, pl. 18, fig. 1a-f).

AGE AND LOCATION OF TYPE MATERIAL. — Upper Kungurian, Koselev Formation, right bank of the River Aj, Aloga Zovo village, Cis-Urals, Russia.

TAXON CODE. — 202.

STATUS. — Junior synonym of Octatormentum Nazarov & Ormiston, 1985 (by De Wever et al. 2001).

DIAGNOSIS. — “Mit den Familienmerkmalen. Schale aussen subsphärisch, gerundet subpolyhedrisch bis gerundet bipyramidal. Die Windungshöhe der Schale nimmt von innen nach aussen zunächst etwas zu, in der letzten Windung dagegen stark ab, oder sie bleibt durchgehend annähernd gleich hoch. Von den 6 dreikantigen Hauptstacheln zweigen Apophysen ab, welche die Hauptstacheln mit der Schale verbinden. Um die Stacheln herum treten dabei in der Schale sehr grosse Poren auf. In der äusseren niedrigen Windung sind die beiden Schalenwindungen zusätzlich durch stachelförmige Stützbalken miteinander verbunden.” ( Kozur & Mostler 1989: 185). DIAGNOSIS (English translation by J. P. Caulet RadWorld database – modified by Jörg Maletz). — “With family characteristics. Shell with a sub-spherical, rounded sub-polyhedral to bi-pyramidal, outline. The coil height of the shell spirals develop increases the inner to the outer side; in the last turn, however, the spiral decreases rapidly, or remains constant. Branched apophyses develop from the 6 three-sided main spines, linking the spines to the shell wall. Very large pores are found around the spines. Secondary spine-like bars connect the outer two cortical shell spirals.”

REMARKS This genus was synonymized with Octatormentum Nazarov & Ormiston, 1985 because of the strong similarity in the coiling, the shell wall structure, and disposition of the spines and bars.
