What is "myriochelata"

The Myriochelata or Paradoxopoda, is a proposed grouping of arthropods comprising the Myriapoda (including millipedes and centipedes) and Chelicerata (including spiders and scorpions). It is the sister clade to the Tetraconata.

The evidence for this relationship between myriapods and chelicerates derives from comparisons of nuclear ribosomal RNA genes, mitochondrial ribosomal RNA genes, and protein-coding genes. More recent molecular studies, however, favour grouping the myriapods with crustaceans and insects, rather than with the chelicerates, to make up the clade Mandibulata.
