InversotyphlusStrasser, 1962,stat. nov.is raised to the genus level and a new hydrophilous species,Inversotyphlus ammirandussp. nov., is described from the second deepest pit in Albania. This species is characterized by a highly modified head and body for a presumably semiaquatic or hygropetric life and filtering diet. It is by far the most bizarrely modified cave-dwelling julid known. The new species is diagnosed, described in detail, and richly illustrated. BesidesI. ammirandussp. nov., the genusInversotyphlusstat. nov.includes six species:I. clavatus(Antić, 2018),comb. nov.,I. edentulus(Attems, 1951),comb. nov.,I. gellianae(Makarov & Rađa, 2006),comb. nov.,I. gracilis(Antić, 2018),comb. nov.,I. lobifer(Attems, 1951),comb. nov., andI. opisthonodus(Antić, 2018)comb. nov.The subgenus Attemsotyphlussyn. nov.is here considered as a junior subjective synonym of the genusInversotyphlusstat. nov.Notes are given on the habitat ofI. ammirandussp. nov., the taxonomy of the tribe Typhloiulini and the genusInversotyphlusstat. nov., and adaptive modifications of the mouthparts.
