Panarthropoda is a proposed animal clade combining the extant phyla Arthropoda, Tardigrada and Onychophora,[1] a clade, "Lobopodia", and a single class, the Dinocaridida. Not all studies support it,[2] but most do, including neuroanatomical,[3] mitogenomic[4] and palaeontological[5][6] studies. Originally, they were considered to be closely related to the annelids, grouped together as the Articulata, but newer studies place them among the Ecdysozoa.
Common characteristics of the Panarthropoda include the presence of legs and claws, a ventral nervous system, and a segmented body.

Sialomorpha a genus of mite and tardigrade like microinvertebrate discovered in Dominican amber in 2019 also belongs to this group, thought its exact placement is uncertain.[7]
