Páll-Gergely, Barna, Fehér, Zoltán, Hunyadi, András & Asami, Takahiro, 2015, Revision of the genus Pseudopomatias and its relatives (Gastropoda: Cyclophoroidea: Pupinidae), Zootaxa 3937 (1), pp. 1-49 : 16

Genus Csomapupa Páll-Gergely , n. gen.

Type species. Pomatias grandis Godwin-Austen, 1876.

Diagnosis. Shell large, turriform/spindle-shaped, regularly ribbed, ribs very low and weak; shallow "scoring" or groove above the suture; aperture oval with very smooth columellar-parietal and parietal-palatal transitions; peristome very much widened; operculum thin.

Differential diagnosis. Differs from Vargapupa n. gen. and Nodopomatias by the absence of a basal keel, and from Pseudopomatias by the presence of a shallow groove above the suture. Csomapupa n. gen. species have conspicuously widened peristome margin, which is wider than in any species of Pseudopomatias . The parietalpalatal transition of the aperture is not angled in Cs. luyorensis , but very slightly angled in Cs. grandis . In Pseudopomatias this transition is usually much more conspicuous.

Etymology. The new genus Csomapupa (gender feminine) is dedicated to Sándor Kőrösi Csoma (1784?–1842), also known as Alexander Csoma de Kőrös (approximate pronunciation is “choma”), Hungarian- Szekler (Székely) philologist and orientalist, author of the first Tibetan-English dictionary and grammar book. The name Csomapupa is the combination of the family name Csoma and Pupa.

Content. Cs. grandis ( Godwin-Austen, 1876) , Cs. luyorensis ( Godwin-Austen, 1917) .

Distribution ( Fig. 7 ): The two species of Csomapupa n. gen. were reported from the Dafla and Abor Hills (north-eastern India) (see also Fig. 2 ).
