Lower Heterobranchia, also known as the Allogastropoda, is a group of rather specialized, highly evolved
Although the great majority of Lower Heterobranchs are indeed marine, a few have succeeded in making the transition to
Description
The shell shapes in this group are typically those that are seen in the sundial, pyramid, rissoella and orbitestellid families of snails.[2]
Taxonomy
2005 taxonomy
In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005,[3] the Lower Heterobranchia is an Informal Group. Superfamilies within the Lower Heterobranchia include:
- Unassigned to a superfamily (orbitestellid-shells)
- Family Cimidae
- † Family Dolomitellidae
- † Family Heterosubulitidae
- † Family Kuskokwimiidae
- † Family Misurinellidae
- Family Orbitestellidae
- Family Tjaernoeiidae
- Family Xylodisculidae
- superfamily Acteonoidea
- superfamily Architectonicoidea
- superfamily Glacidorboidea
- superfamily Mathildoidea
- † superfamily Nerineoidea
- superfamily Omalogyroidea
- superfamily Pyramidelloidea
- superfamily Ringiculoidea
- superfamily Rissoelloidea
- † superfamily Streptacidoidea
- superfamily Valvatoidea
(Taxa that are exclusively fossil are indicated with a dagger †)
For a more detailed taxonomy see: Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005)#Informal group "Lower Heterobranchia" (= Allogastropoda)
2010 taxonomy
Jörger et al. (2010)
2014 taxonomy
Wägele et al. (2014):
2016 taxonomy

So the following taxa remain within the Lower Heterobranchia:
- Unassigned to a superfamily (orbitestellid-shells)
- Family Cimidae
- † Family Dolomitellidae
- † Family Heterosubulitidae
- † Family Kuskokwimiidae
- † Family Misurinellidae
- Family Orbitestellidae
- Family Tjaernoeiidae
- Family Xylodisculidae
- superfamily Architectonicoidea
- superfamily Mathildoidea
- † superfamily Nerineoidea
- superfamily Omalogyroidea
