Gittenberger, Edmund, Kokshoorn, Bas, Boessneck, Ulrich, Reijnen, Bastian T. & Groenenberg, Dirk S. J., 2016, Granopupa in Iran, monophyly, and the fossil Granariinae (Gastropoda, Pulmonata, Chondrinidae), ZooKeys 592, pp. 27-37 : 33-34

Taxon classification Animalia Pulmonata Chondrinidae

Graniberia Gittenberger, Groenenberg & Kokshoorn gen. n.

Diagnosis.

Columellaris much more prominent than the infracolumellaris, which is not or hardly visible in frontal view; palatal lamellae reaching their maximum prominence clearly deeper than half a whorl inside the last whorl; apertural lip strongly reflected and broadly thickened.

Type species.

Graniberia braunii ( Rossmässler, 1842) Figure 4C.

Remarks.

The three extant Granaria species, the fossil taxa that are currently classified with Granaria , and the four known Granopupa species, all differ from Graniberia braunii in the characters mentioned in the diagnosis.

In all Granaria and Granopupa species and in the other Chondrinidae species with an apertural dentition that is not reduced, viz. several Abida and Chondrina species, the infracolumellaris is clearly visible. Therefore, an obsolete infracolumellaris as in Graniberia braunii , is considered the apomorphic character state. For both the location of the palatal lamellae and the prominence of the apertural lip this is also concluded. A similar reasoning is accepted here, with only the marginal note that very few Abida and Chondrina species have more or less clearly developed a thickened apertural border, whereas in only very few Abida species deep palatal folds occur.Two subspecies are currently recognized, viz. Graniberia braunii braunii ( Rossmässler, 1842) and Granaria braunii marcusi (Gittenberger & Ripken, 1993).

Derivatio nominis.

Graniberia after the distribution of a genus resembling Granaria in the Iberian peninsula.
