ABSTRACT: Rheodithella kalashana gen.n., sp.n., is described from Chitral, in the Hindu Kush Range of Northwest Pakistan. Rheodithella gen.n. is the first representative of the subfamily Verrucadithinae Chamberlin, 1929 (new status) known from the Palaearctic. A revised diagnosis of the related South American genus Cryptoditha Chamberlin rt Chamberlin, 1945 is given, based on an examination of the type species, C. elegans (Beier, 1931). The Brazilian species Verrucadithella francisi Feio, 1945 is transferred to Cryptoditha, comb.n. A key is given to the genera of the Verrucadithinae. The genus Anisoditha Chamberlin et Chamberlin, 1945 is removed from the Tridenchthoniidae Balzan, 1892 and assigned to the Chthoniidae Daday, 1888.
