Key to Tormus species

Morphologically, the species of Tormus may be reliably identified only by the examination of the male genitalia, but both species were never found in sympatry and locality data may therefore be useful for quick identification. See above for details on genetically distinct haplotypes here considered as belonging to T. helmsi .
