在系统发育分析的过程中，讨论了100多个与裸鳃亚目有关的形态、解剖和组织学特征。根据我们自己的解剖学，组织学和发表的文献的调查，每个字符的极性进行评估，通过比较其表达与外群，主要是侧鳃亚目，但也与其他后鳃类群（头盾目，Anaspidea，Sacoglossa），并最终与肺，Vetiastropoda和Caenogastropoda。通过提取30个分类单元的46个特征，利用PAUP程序对裸鳃亚目主要类群进行了系统发育分析。裸鳃类新分类单元（包括侧鳃总科加裸鳃亚目）的定义。裸鳃类、花鳃类（包含Bathydoridoidea加Doridoidea）和枝鳃类（包含Dendronotoidea加Aeolidoidea和'Arminoidea'）的单系性得到确认，并强调了自形性。论证了“Arminoidea”的并系性。在较低的分类水平的不协调进行了讨论。
More than 100 morphological, anatomical and histological characters pertaining to the Nudibranchia are discussed in the course of a phylogenetic analysis. Based on our own investigations on anatomy, histology and published literature, the polarity of each character is assessed by comparing its expression with outgroups, chiefly the Pleurobranchoidea, but also with other opisthobranch taxa (Cephalaspidea, Anaspidea, Sacoglossa), and ultimately with the Pulmonata, Vetigastropoda and Caenogastropoda. By extracting 46 applicable characters expressed in 30 taxa, a phylogenetic analysis of the major groups of the Nudibranchia is performed by using the computer program PAUP. Nudipleura new taxon (containing the Pleurobranchoidea plus Nudibranchia) is defined. The monophyly of the Nudibranchia, the Anthobranchia (containing the Bathydoridoidea plus Doridoidea), and the Cladobranchia (containing the Dendronotoidea plus Aeolidoidea and ‘Arminoidea’) are confirmed and autapomorphies are highlighted. The paraphyly of the ‘Arminoidea’ is demonstrated. Incongruities at lower taxonomic level are discussed.
