Abstract

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 Plateaus, southeastern USA. The neotype of Foveacheles holsingeri Zacharda, 1980 is assigned, the species is redescribed and together with Foveacheles paralleloseta Zacharda, 1985, transferred 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. The biogeography, morphological adaptations to life in caves (troglomorphisms), vicariance and distribution of the presented taxa are briefly discussed. All new taxa are authored by M. Zacharda only. copyright
