Phyla

Tetraneuralia is a proposed clade of spiralian bilaterians uniting the phyla Mollusca and Entoprocta. First proposed in 2009 based on similarities between entoproct larvae and polyplacophoran molluscs,[1] it was recovered in 2019 in a phylogenomic study by Marlétaz et al.[2]

Phylogeny

In the most recent study, Tetraneuralia was recovered at the base of Lophotrochozoa.[2]
