Dondale in 1966 made Cheiracanthium diversum and Cheiracanthium gilvum synonyms of C. mordax, meaning there were thereafter to be considered the same species. The differences between the species the considered to be within natural variation of a widespread and abundant species such as C. mordax. DNA studies may help us confirm these synonymies, or show the previous species were distinct. There seems to be anecdotal evidence suggesting the current scope of C. mordax might contain subgroups which might be separate species.
