The genus Inversotyphlus Strasser, 1962, stat. nov. and Inversotyphlusammirandus sp. nov., a new bizarre, highly modified troglobiotic millipede (Diplopoda, Julida, Julidae) from Albania, Balkan Peninsula.

Inversotyphlus Strasser, 1962, stat. nov. is raised to the genus level and a new hydrophilous species, Inversotyphlusammirandus sp. 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. Besides I.ammirandus sp. nov. , the genus Inversotyphlus stat. 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. , and I.opisthonodus (Antić, 2018) comb. nov. The subgenus Attemsotyphlus syn. nov. is here considered as a junior subjective synonym of the genus Inversotyphlus stat. nov. Notes are given on the habitat of I.ammirandus sp. nov. , the taxonomy of the tribe Typhloiulini and the genus Inversotyphlus stat. nov. , and adaptive modifications of the mouthparts.
