Thysanophoridae
Thysanophoridae is a family of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the superfamily Helicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). These are common woodland snails of North America. They also occur in a few recorded spots in South America. This family is defined by the absence of both a diverticulum and a stimulatory organ. Subfamilies There are no subfamilies in Thysanophoridae. Genera Genera within the family Thysanophoridae include: *'' Hojeda'' H. B. Baker, 1926 * ''Itzamna'' (unconfirmed) *'' Lyroconus'' (unconfirmed) * '' Mcleania'' (unconfirmed) *'' Microconus'' (unconfirmed) *'' Microphysula'' Cockerell, 1926 - Spruce snails *'' Miroconus'' (unconfirmed) *'' Pulchriconus'' (unconfirmed) *'' Setidiscus'' (unconfirmed) *'' Suavitas'' (unconfirmed) *'' Thysanophora'' Strebel & Pfeffer, 1880 - the type genus In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biol ...

Helicoidea
Helicoidea is a Taxonomy (biology), taxonomic Taxonomic rank, superfamily of air-breathing land snails, terrestrial molluscs, terrestrial pulmonate gastropod mollusks in the order (taxonomy), order Stylommatophora. Taxonomy 2017 taxonomy and latest developments The Bouchet et al. 2017 nomenclator provides an up to date system of Helicoidea. The system is in some parts preliminary, as the authors relied on unpublished (as of 2023) Phylogenomics, phylogenomic study, which did not include all New World taxa. They classified Epiphragmophoridae, Helminthoglyptidae, Humboldtianidae, Monadeniidae and Xanthonychidae (provisionally also Lysinoidae and Echinichidae) as Subfamily, subfamilies of the last taxon, because there are no deep splits between them in the cited unpublished study (see also Koene & Schulenburg 2005). Cepolidae, Labyrinthidae and Thysanophoridae constitute the sister group of the remaining Helicoidea. * Camaenidae Pilsbry, 1895 * Canariellidae Schileyko, 1991 * Cepo ...

Pulmonate
Pulmonata or pulmonates is an informal group (previously an order, and before that, a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous period to the present. Pulmonates have a single atrium and kidney, and a concentrated symmetrical nervous system. The mantle cavity is on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater). The paper setting out this taxonomy was published in the journal '' Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Type Genus
In biological taxonomy, the type genus (''genus typica'') is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens ...
