The researchers combined these data with a global phylogeny of all plant species and the world's largest database of plant traits, 'TRY'.

"It describes a new genus and species, but places them in the phylogeny of tardigrades," Nelson told Salon.

Next, the team mapped out the branches of the phylogeny that featured living bioluminescent species.

The results corroborated the systematic membership of Dermaptera to Polyneoptera and strongly supported the phylogeny within the order, which was inferred from the latest molecular phylogenetic analyses but was significantly different from the conventional understanding.

"Acoustic communication, broadly distributed along the vertebrate phylogeny, plays a fundamental role in parental care, mate attraction and various other behaviours."
