When discrete characters are wanting: Continuous character integration under the phylospecies concept informs the revision of the Australian land snail Thersites (Eupulmonata, Camaenidae) Open
Species that are predominantly characterized by continuous instead of discrete morphological characters pose a challenge to species delimitation. Under the phylospecies concept, species are delimited by apomorphies, which are difficult to …
