Antennopoda
The Antennopoda (or Arthropoda s.l.) are a proposed clade consisting of the Euarthropoda and the Onychophora, as sister of the Tardigrada, together forming the Panarthropoda. Stanleycaris appears to be a basal Euarthropod. Antennopoda was defined by De Haro, where Tardigrada was not included in his tree. In a subsequent article of him, his use of Antennopoda was inconsistent with the current usage. Especially the position of the Tardigrada is disputed, the alternative hypothesis of Tactopoda includes tardigrades and arthropods as the sister group to velvet worms. References
