The genus contains a <a href="/wiki/Monotypic_taxon" title="Monotypic taxon">single species</a>, <i><b>Ardetosaurus viator</b></i>. It was first described in 2024 on the basis of a partial articulated skeleton, including vertebrae from the neck, back, and tail, hip bones, and part of the left hindlimb.
