Trissexodontidae
Template:Short description Template:Automatic taxobox
Trissexodontidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
This family has no subfamilies.[1] The family Trissexodontidae was separated out from the families Hygromiidae and Helicodontidae,[1] and some authors still classify these species within those families.
Distribution
The distribution of Trissexodontidae includes the Iberian Peninsula, northwest Africa,[2] Azores,[3] Canary Islands, Madeira and Cape Verde.[4]
Genera
Genera within the family Trissexodontidae include:
- Caracollina Beck, 1837[2]
- Gasullia Ortiz de Zárate López, 1962[2]
- Gasulliella Gittenberger, 1980[2] - with only one species, Gasulliella simplicula (Morelet, 1845)
- Gittenbergeria Schileyko, 1991[2]
- Mastigophallus Hesse, 1918[2] - with only one species, Mastigophallus rangianus (Michaud, 1831)
- Oestophora Hesse, 1907[2]
- Oestophorella Pfeffere, 1929[2]
- Trissexodon Pilsbry, 1895[2] - type genus of the family Trissexodontidae
- Spirorbula Lowe, 1852 - probable classification,[2] from Madeira and Porto Sancto[5]
- Suboestophora Ortiz de Zárate López, 1962[6]
Description
Shells of species in the family Trissexodontidae are flat and regularly ribbed. The periostracum of the shell surface has no hairs.[2]
A description of the reproductive system was summarized by Prieto et al. (1993).[2]
In this family, the number of haploid chromosomes is known only for the genus Oestophora (n=30).[2]
