The Amphipoda includes a large clade defined by the presence of a previously unrecognised synapomorphy, apical robust setae on the rami of uropods 1-2. We term this clade the Senticaudata subord. nov. (Latin: sentis = thorn). It includes almost all freshwater species as well as a number of marine benthic taxa, formerly part of the 'Gammaridea'. The phylog-eny of the senticaudates was determined by cladistic analysis of morphological characters and character states. Within the suborder Senticaudata there are six infraorders: Carangoliopsida, Talitrida, Hadziida, Corophiida, Bogidiellida and Gam-marida. A classification is provided and all the senticaudate families are diagnosed. We introduce for the first time in am-phipod classification, the level parvorder between infraorder and superfamily. Four new families are described: Kairosidae; Eriopisidae; Nuuanuidae and Kergueleniolidae.
端足目包括一个大型分支，其定义特征是在第1 - 2尾足的鳃上存在一种先前未被识别的共衍征——顶端粗壮刚毛。我们将这个分支命名为Senticaudata subord. nov.（拉丁语：sentis = 刺）。它几乎包括所有淡水物种以及一些海洋底栖类群，这些类群以前是“钩虾亚目”的一部分。通过对形态特征和特征状态进行分支分析，确定了Senticaudata分支的系统发育。在Senticaudata亚目内有六个下目：Carangoliopsida、Talitrida、Hadziida、Corophiida、Bogidiellida和Gammarida。给出了一个分类，并对所有Senticaudata分支的科进行了诊断。我们在端足目分类中首次引入了下目和总科之间的“小目”级别。描述了四个新科：Kairosidae；Eriopisidae；Nuuanuidae和Kergueleniolidae。
