Tomigerus is a genus of air-breathing, tropical land snails, terrestrial pulmonate gastropod mollusks in the family Tomogeridae.Breure A. S. H. & Ablett J. D. (2012) "Annotated type catalogue of the Bothriembryontidae and Odontostomidae (Mollusca, Gastropoda, Orthalicoidea) in the Natural History Museum, London". ZooKeys 182: 1-70. .
Species This genus contains the following species: Tomigerus clausus Spix, 1827 Tomigerus corrugatus Ihering, 1905 Tomigerus esamianus Salgado & Coelho, 1990 Tomigerus laevis Ihering, 1905 Tomigerus matthewsi Salgado & Leme, 1991 Tomigerus pilsbryi Baker, 1914 Tomigerus rochai Ihering, 1905
Synonyms: Tomigerus gibberulus is a synonym of Digerus gibberulus (Burrow, 1815) Norma Campos Salgado & Arnaldo C. dos Santos Coelho. (2003). "Moluscos terrestres do Brasil (Gastrópodes operculados ou não, exclusive Veronicellidae, Milacidae e Limacidae)" . Rev. Biol. Trop. 51(Suppl. 3): 149-189. (with English abstract) - extinct Tomigerus turbinatus is a synonym of Biotocus turbinatus (Pfeiffer, 1845) - extinct
How the shell is carried It is evident from several features of the shell and its internal organization that the shell in this genus is carried with its principal axis transverse to the longitudinal axis of the foot; that is, the spire is directed to the right. The flattened surface of the outer whorl thus rests upon the dorsal surface of the foot or upon the substratum when the animal is in a state of aestivation, a position which they had assumed in both instances.
