A new crinoid fauna is described from the Trogkofel Group of the Southern Karavanke Mountains, Slovenia (lower Permian, Artinskian). This fauna is from a shallow platform or upper slope setting and is comprised primarily of isolated aboral cups. One taxon, Protencrinus baliensis, previously described from the lower Permian of Crete, is the only species known from elsewhere. New taxa from the Trogkofel Group include Karavankecrinus bedici gen. et sp. nov., Moapacrinus dovjensis sp. nov., Parastachyocrinus sloveniaensis sp. nov., and Sinocrinus websteri sp. nov. Several taxa are left in open nomenclature, including Dieuryocrinus? sp., Platycrinitidae indet., Eucladida indet. A, and unidentified Crinoidea. If Dieuryocrinus? sp. belongs to Dieuryocrinus, this would expand the range of this genus, previously known from the Viséan (Mississippian) of the United Kingdom. Other genera are well known as lower Permian taxa. In addition, the species-level systematics of Parastachyocrinus is revised, and one new species from the lower Permian of Timor is described, P. wanneri sp. nov.
Key words: Echinodermata, Crinoidea, Permian, Europe, Southern Calcareous Alps, Slovenia.
