A Maximum likelihood phylogenetic reconstruction with ultrafast bootstrapping (5000 replicates) B bayesian phylogenetic reconstruction with posterior probabilities, constructed using MrBayes analysis. Phylogenetic analyses were conducted using concatenated sequence alignments of partial 16S and CO1 mtDNA. The analyses consist of 69 ingroup taxa (11 taxa representing the “scaly” group and 58 taxa representing the “non-scaly” group), and Bathynerita naticoidea as an outgroup. “Scaly” taxa in the phylogenies are with the red branches.
