Praeholdsworthella Kozur & Mostler, 1989

Praeholdsworthella Kozur & Mostler, 1989: 184 .

TYPE SPECIES. — Albaillella amplificata Nazarov & Ormiston, 1985 ( Nazarov & Ormiston 1985: 46, pl. 6, fig. 8, text-fig. 10a).

AGE AND LOCATION OF TYPE MATERIAL. — Sakmarian, Cis-Urals, Russia.

TAXON CODE. — 038.

STATUS. — Junior synonym of Parafollicucullus (by Dumitrica & Caridroit in De Wever et al. 2001: 93).

DIAGNOSIS. —“Gehäuse dreigeteilt, unperforiert. Apicalkegel unsegmentiert. Pseudothorax recht klein, aber bereits deutlich vom Pseudoabdomen abgesetzt, sphärisch bis subsphärisch.Dorsal und ventral sitzt je ein kleiner bis mässig langer Seitenstachel an. Pseudoabdomen lang, seitlich abgeflacht, unsegmentiert. Apertur oval, endständig. Die Columella laufen apical zusammen und sind distal frei. Die freien Columella sind sehr lang, hoch, gerade und aussen kräftig bestachelt (je 3-4 Stacheln). An der Innenseite der ventralen Columella treten 1-2 Paare von freien Trabekeln auf.” ( Kozur & Mostler 1989: 184).

DIAGNOSIS (English translation by J. P. Caulet – RadWorld database). — “Test differentiated into three parts, imperforate. Apical cone unsegmented.Pseudothorax rather small, but well-differentiated from the pseudoabdomen, spherical to sub-spherical. Small to moderately long spines on ventral and dorsal sides. Pseudoabdomen long, laterally flattened, not segmented. Aperture oval, terminal. Columellae apically joined and distally free. Free parts of columellae very long, straight, with external strong spines (3-4). 1-2 pairs of free trabeculae on the inner side of the ventral columella.”

REMARKS

This genus is synonymized with Pseudoalbaillella in De Wever et al. (2001: 93) . Parafollicucullus is considered the senior synonym to Pseudoalbaillella and by extension to Foremanconus .
