Study – never previously tackled – of male genitalia variability in Tinodes assimilis McLachlan, leads to the description of a new subspecies from the Rif of Morocco, clearly distinct from most populations from the Iberian Peninsula (although specimens from some of the southernmost provinces of Spain may show a slightly intermediate pattern, as a result of panmixy/introgression in a contact zone). As for Tinodes dives Pictet, a species whose variability had already been partly studied, the situation is more complex; the authors interpret it as a superspecies comprising three already named prospecies, one more (from Cordillera Cantabrica) being here described as new, whereas some uncertain situations are discussed.
