腹足纲的谱系学分类

本页面旨在呈现腹足纲的系统发生学分类的一个可能性。利用树状结构，本页面详列出腹足纲之下各个物种的关系。页面尽可能采纳最新的分析证据，并把证据详列于本文底部。不过，科学界对于部分分类的意见未必一致。
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。
过往分类.
1997年分类.
过去腹足类曾分为三个亚纲，分别如下：
前鳃亚纲后来证实是一个并系群，所以从1997年开始取消了这个分类，提升成为 真腹足亚纲（Eogastropoda）；旗下的中腹足目与新腹足目合并成为新进腹足类（Caenogastropoda）。
2010年及以后的分类转变.
In one of the largest recent changes (affecting the most species of gastropods), Klussmann-Kolb "et al." (2008) showed that the traditional classification of the Euthyneura needed to be reconsidered. The change was subsequently made by Jörger "et al." (2010), who redefined the major groups within the Heterobranchia.
现时，我们已清楚太阳女神螺纲（Helcionelloida）的化石并不是腹足纲的成员，而是软体动物门之下的一毎独立的纲，帕哈耶夫 (2006, 2007)亦因此建议成立这一个纲，以取代过往在布歇特和洛克罗伊的腹足类分类 (2005年)的分类中有关「系统分类地位未定的古代软体动物」分类。这个纲包括下列各物种：
Subclass Archaeobranchia Parkhaev, 2001
Subclass Divasibranchia Minichev & Starobogatov, 1975
Subclass Dextrobranchia Minichev & Starobogatov, 1975
Patellogastropoda根据Nakano & Ozawa (2007)的研究重写，但这个建议有争议。根据中野等人的旧文献，青螺科（Acmaeidae）被认为是莲花青螺科（Lottiidae）的同种异名；另一方面，; the subfamily Pectinodontinae is elevated to Pectinodontidae; a new family Eoacmaeidae with the new type genus "Eoacmaea" is established. The remaining three families (Neolepetopsidae, Daminilidae, Lepetopsidae) are moved into the Lottioidea, like this:
但数年后中野智之再发表文献，指当初研究的结果是由于实验标本受到污染所引致，因此又将青螺科和莲花青螺科分开。不过网上有不少数据库已跟随中野的建议合并了两个科。其他受影响的文献仍不时可以找到。
一个Depressizona新物种的发现，令Geiger (2009) elevated the subfamily Depressizoninae to family level as Depressizonidae. Also two subfamilies (the Larocheinae from the Scissurellidae, and the Temnocinclinae from the Sutilizonidae) were upgraded to family level as the Larocheidae and the Temnocinclidae.
The superfamily Trochoidea was redefined by Williams et al. (2008) and the superfamily Turbinoidea is no longer used. Phasianelloidea and Angarioidea were created as new superfamilies.
Trochoidea
Phasianelloidea
Angarioidea
Bandel (2007) described four new families within the Neritopsoidea. He classified Neritopsoidea in the order Neritoina within the superorder Cycloneritimorpha and within the subclass Neritimorpha. Bandel (2007) recognizes Natisopsinae (in Neritopsidae by Bouchet & Rocrois 2005) at the family level, as Naticopsidae. Bandel's classification looks like this:
superfamily Neritopsoidea
The family Provannidae was moved to the superfamily Abyssochrysoidea Tomlin, 1927. In addition, a new family Hokkaidoconchidae Kaim, Jenkins & Warén, 2008 was named.
The subfamily Semisulcospirinae, within the Pleuroceridae, was elevated to the family level Semisulcospiridae by Strong & Köhler (2009).
Bandel (2006) made numerous changes in the following clades: Cerithimorpha/Cerithioidea, Turritellimorpha/Turritelloidea, Murchisonimorpha/Orthonematoidea, Campanilimorpha/Campaniloidea and Ampullinoidea, Vermetimorpha/Vermetoidea.
Fehse (2007) elevated both the subfamily Pediculariinae and the tribe Eocypraeini (which were previously in the family Ovulidae) to family level, based on both morphological research and molecular phylogeny research. Families within Cypraeoidea are now as follows:
Within the Tonnoidea, Beu (2008) raised the subfamily Cassinae to the rank of family: Cassidae Latreille, 1825.
Bouchet et al. (2011) have updated taxonomy of the superfamily Conoidea:
Janssen (2005) established a new family, Praecuvierinidae.
Gosliner et al. (2007) elevated the subfamily Babakininae to the family level as Babakinidae.
Golding et al. (2007) established new families within the Amphiboloidea:
Uit de Weerd (2008) moved two families Urocoptidae and Cerionidae to the newly established superfamily Urocoptoidea, based on molecular phylogeny research as follows:
superfamily Urocoptoidea
Other authors also made numerous taxonomic changes within Orthalicoidea in 2009-2012.
Schrödl & Neusser (2010) rearranged the taxonomy of the Acochlidiacea.
Swennen & Buatip (2009) described a new family Aitengidae, which was later moved to Acochlidiacea by Jörger et al. (2010).
Malaquias et al. (2009) rearranged the taxonomy of the Cephalaspidea "sensu lato": reinstated Architectibranchia, reinstated Runcinacea, reinstated Scaphandridae as a valid family, but they did not use superfamilies.
Subsequently Malaquias (2010) moved "Bullacta exarata" (formerly the only member of Bullactidae) into the family Haminoeidae.
Sutcharit et al. (2010) established a new family Diapheridae within the Streptaxoidea in 2010.
Jörger et al. (2010) redefined major groups of Heterobranchia and created the new clades 和。
Maeda et al. (2010) confirmed the placement of "Cylindrobulla" within the Sacoglossa.
Thompson (2010) redefined subfamilies in Spiraxidae, moving Euglandininae and Streptostylinae (from where they had been in the Oleacinidae per Bouchet & Rocroi (2005)) so that they became subfamilies of Spiraxidae.
Johnson (2011) resurrected the family Cadlinidae.
Thompson (2012) established a new family, Epirobiidae.
Thompson & Naranjo-García (2012) described a new family Echinichidae within Xanthonychoidea.
