Xenocarida (from the Greek for strange shrimp) is a proposed clade inside the subphylum Crustacea that comprises two classes that were discovered in the 20th century: Remipedia and Cephalocarida. Both groups are marine hermaphrodites.[1][2] The clade was recovered as the sister groups to Hexapoda (including insects).[3]

However, other studies do not recover Xenocarida as a monophyletic group[4][5] and variously find Branchiopoda or Remipedia as the hexapod sister group[6][7][4][5]
