Remarks: Bichuette and Trajano (2018) list 12 morphospecies of Potamolithus in the same overall area in the Upper Ribeira Valley as P. troglobius above and the related troglophilic P. karsticus Simone & Moracchioli, 1994 (known from Calcário Branco cave, including epigean; Fig. 10). Of those 12 morphs, five are deemed to be troglobites, six troglophiles, and one epigean. Potamolithus spp. are restricted to micro-basins and/or caves, showing small areas of distribution and probably a high degree of endemism. Whether they are indeed new species remains to be fully investigated.
