A new supplemented concept of the genus Traegaardhia Zacharda,1980 (Acari:Rhagidiidae)is presented and descriptions of seven new species of the genus are given.These are Traegaardhia cavernarum n.sp.,T.cavernicola n.sp.,T. distosolenidia n.sp.,T.gracilis n.sp., T.nasuta n.sp.,T. subterranea n.sp.,from caves located in northeastern Prealps, Italy,and T.similis n.sp.from the Ozark Plateaussoutheastern USA. The neotype of Foveacheles holsingeri Zacharda, 1980 is assigned,the species is redescribed and together with Foveacheles paralleloseta Zacharda, 1985transferred into the genus Traegaardhia.Foveacheles thaleri n.sp.is described as the possible epigean ancestor of the derivative troglobiotic T.subterranea and the adaptive shift hypothesis and parapatric speciation of T.subterranea is outlined.A key to adults of the known eleven species of the genus Traegaardhia is presented.
