腹足綱的譜系學分類

本頁面旨在呈現腹足綱的系统发生学分類的一個可能性。利用樹狀結構，本頁面詳列出腹足綱之下各個物種的關係。頁面盡可能採納最新的分析證據，並把證據詳列於本文底部。不過，科學界對於部分分類的意見未必一致。
腹足纲是软体动物门中重要的组成部分，是软体动物门中最大的纲，约60,000到80,000生存种。包括约409个现生的科，另外还有约202个化石科。

過去腹足类曾分为三个亚纲，分別如下：
前鳃亚纲後來證實是一個並系群，所以從1997年開始取消了這個分類，提升成為真腹足亚纲（Eogastropoda）；旗下的中腹足目與新腹足目合併成為新进腹足类（Caenogastropoda）。
In one of the largest recent changes (affecting the most species of gastropods), Klussmann-Kolbet al.(2008)showed that the traditional classification of theEuthyneuraneeded to be reconsidered. The change was subsequently made by Jörgeret al.(2010),who redefined the major groups within theHeterobranchia.
現時，我們已清楚太陽女神螺綱（Helcionelloida）的化石並不是腹足綱的成員，而是軟體動物門之下的一毎獨立的綱，帕哈耶夫(2006, 2007)亦因此建議成立這一個綱，以取代過往在布歇特和洛克羅伊的腹足類分類 (2005年)的分類中有關「系統分類地位未定的古代軟體動物」分類。這個綱包括下列各物種：
SubclassArchaeobranchiaParkhaev, 2001
SubclassDivasibranchiaMinichev & Starobogatov, 1975
SubclassDextrobranchiaMinichev & Starobogatov, 1975
Patellogastropoda根據Nakano & Ozawa (2007)的研究重寫，但這個建議有爭議。根據中野等人的舊文獻，青螺科（Acmaeidae）被認為是蓮花青螺科（Lottiidae）的同種異名；另一方面，; the subfamily Pectinodontinae is elevated toPectinodontidae; a new familyEoacmaeidaewith the new type genusEoacmaeais established. The remaining three families (Neolepetopsidae, Daminilidae, Lepetopsidae) are moved into the Lottioidea, like this:
但數年後中野智之再發表文獻，指當初研究的結果是由於實驗標本受到污染所引致，因此又將青螺科和蓮花青螺科分開。不過網上有不少數據庫已跟隨中野的建議合併了兩個科。其他受影響的文獻仍不時可以找到。
一個Depressizona新物種的發現，令Geiger (2009)elevated the subfamily Depressizoninae to family level asDepressizonidae. Also two subfamilies (the Larocheinae from the Scissurellidae, and the Temnocinclinae from the Sutilizonidae) were upgraded to family level as theLarocheidaeand theTemnocinclidae.
The superfamily Trochoidea was redefined by Williams et al. (2008)and the superfamilyTurbinoideais no longer used. Phasianelloidea and Angarioidea were created as new superfamilies.
Trochoidea
Phasianelloidea
Angarioidea
Bandel (2007)described four new families within theNeritopsoidea. He classified Neritopsoidea in the orderNeritoinawithin the superorderCycloneritimorphaand within the subclassNeritimorpha.Bandel (2007) recognizes Natisopsinae (in Neritopsidae by Bouchet & Rocrois 2005) at the family level, asNaticopsidae. Bandel's classification looks like this:
superfamilyNeritopsoidea
The familyProvannidaewas moved to the superfamilyAbyssochrysoideaTomlin, 1927.In addition, a new familyHokkaidoconchidaeKaim, Jenkins & Warén, 2008was named.
The subfamily Semisulcospirinae, within thePleuroceridae, was elevated to the family levelSemisulcospiridaeby Strong & Köhler (2009).
Bandel (2006)made numerous changes in the following clades:Cerithimorpha/Cerithioidea,Turritellimorpha/Turritelloidea,Murchisonimorpha/Orthonematoidea,Campanilimorpha/CampaniloideaandAmpullinoidea,Vermetimorpha/Vermetoidea.
Fehse (2007)elevated both the subfamily Pediculariinae and the tribe Eocypraeini (which were previously in the familyOvulidae) to family level, based on both morphological research and molecular phylogeny research.Families within Cypraeoidea are now as follows:
Within theTonnoidea, Beu (2008) raised the subfamily Cassinae to the rank of family:CassidaeLatreille, 1825.
Bouchet et al. (2011)have updated taxonomy of the superfamilyConoidea:
Janssen (2005)established a new family,Praecuvierinidae.
Gosliner et al. (2007)elevated the subfamily Babakininae to the family level asBabakinidae.
Golding et al. (2007)established new families within theAmphiboloidea:
Uit de Weerd (2008)moved two familiesUrocoptidaeandCerionidaeto the newly established superfamilyUrocoptoidea, based onmolecular phylogenyresearch as follows:
superfamilyUrocoptoidea
Other authors also made numeroustaxonomic changes within Orthalicoideain 2009-2012.
Schrödl & Neusser (2010)rearranged the taxonomy of the Acochlidiacea.
Swennen & Buatip (2009)described a new familyAitengidae, which was later moved toAcochlidiaceaby Jörger et al. (2010).
Malaquias et al. (2009)rearranged the taxonomy of the Cephalaspideasensu lato: reinstatedArchitectibranchia, reinstatedRuncinacea, reinstatedScaphandridaeas a valid family, but they did not use superfamilies.
Subsequently Malaquias (2010)movedBullacta exarata(formerly the only member of Bullactidae) into the familyHaminoeidae.
Sutcharit et al. (2010)established a new familyDiapheridaewithin theStreptaxoideain 2010.
Jörger et al. (2010)redefined major groups ofHeterobranchiaand created the new cladesEuopisthobranchia和Panpulmonata。
Maeda et al. (2010)confirmed the placement ofCylindrobullawithin theSacoglossa.
Thompson (2010)redefined subfamilies inSpiraxidae, moving Euglandininae and Streptostylinae (from where they had been in theOleacinidaeper Bouchet & Rocroi (2005)) so that they became subfamilies of Spiraxidae.
Johnson (2011)resurrected the familyCadlinidae.
Thompson (2012)established a new family,Epirobiidae.
Thompson & Naranjo-García (2012)described a new familyEchinichidaewithinXanthonychoidea.
