A species group is an informal taxonomic rank into which an assemblage of species within a genus are grouped because of their morphological similarities. Different definitions exist. Some authors use the term for species that share a geographic range and cannot interbreed. Others use the term for a group of related species with separate geographic ranges that might interbreed if opportunity arises. Others use the term for a group that has not yet been sufficiently studied, which might or might not have a monophyletic origin.
