The initial study naming the genus considered 3 species valid, which were originally placed in Lissodus.

[1] Some later studies also included the species Parvodus heterodon (Patterson, 1966) from the Early Cretaceous of England in the genus,[2] though other studies have included this species in the genus Polyacrodus.

[3] Some studies have also included the species "Hybodus" parvidens Woodward, 1916, from the Early Cretaceous of Europe and North America within Parvodus,[4] though again this species has also been assigned to Polyacrodus.

[3][5] A 2023 paper assigned the newly described species P. huizodus from the Early Triassic of China to the genus.

[4] The species Parvodus celsucuspus Rees et al., 2013 has been reported from the Early Cretaceous of England and France.
