Panpulmonata is a taxonomic clade of snails and slugs in the clade Heterobranchia within the clade Euthyneura. [1]

Contents

Panpulmonata was established as a new taxon by Jörger et al. in October 2010. [1]

The older name "Pulmonata" referred to a group of euthyneuran gastropods which were considered to be "air-breathers". In contrast, "Opistobranchia" grouped various, mostly marine euthyneuran lineages, often with reduced shell. Phylogenetic analyses have shown that none of these two groups was monophyletic. [2] The former "Pulmonata" should also include several groups that lack an air-filled lung (Acochlidiacea, Sacoglossa and Pyramidelloidea). The name "Pulmonata" also inaccurate when applied to some of the more traditional pulmonate taxa such as Siphonarioidea or Hygrophila, most members of which lack permanently air-filled lungs as well. [1] To emphasize the complete change in taxonomic concepts following from the molecular phylogenetic analyses but keep some continuity in the naming, Jörger et al. (2010) renamed the expanded "Pulmonata" as Panpulmonata

The clade consists of following taxa: [1] [3]

The order Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia. Bubble shells is another common name for these families of marine gastropods, some of which have thin bubble-like shells. This clade contains more than 600 species.

<span class="mw-page-title-main">Pulmonata</span> Informal group of gastropods

Pulmonata or pulmonates, is an informal group 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.

<span class="mw-page-title-main">Stylommatophora</span> Order of gastropods

Stylommatophora is an order of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon includes most land snails and slugs. Stylommatophorans lack an operculum, but some close their shell apertures with temporary "operculum" (epiphragm) made of calcified mucus. They have two pairs of retractile tentacles, the upper pair of which bears eyes on the tentacle tips. All stylommatophorans are hermaphrodites.

Basommatophora was a term that was previously used as a taxonomic informal group, a group of snails within the informal group Pulmonata, the air-breathing slugs and snails. According to the taxonomy of the Gastropoda, whenever monophyly has not been tested, or where a traditional taxon of gastropods has now been discovered to be paraphyletic or polyphyletic, the term "group" or "informal group" was used.
