All four species found in Europe (Phengaris arion, Phengaris alcon, Phengaris teleius and Phengaris nausithous) have been recorded in the Koroška Region. However, only a handful of localities had previously been reported for these species in the region. Furthermore, with rapid decline of their habitats in the last decades, many of the historical localities may now be unsuitable. In this article, a revision of the previously known localities of all four Phengaris species found in Koroška region was made, with a report on new findings of P. alcon, P. nausithous and P. arion, as well as a confirmation of P. teleius and P. nausithous from one of the known localities. The reported findings are especially relevant from the conservation standpoint for the species in Slovenia, as they are isolated from their respective known rangesVrste iz rodu mravljiščarjev (Phengaris) so ene izmed najbolj ogroženih metuljev v Evropi, med drugim tudi zaradi njihovega parazitskega življenjskega cikla, ki vključuje tako specifično gostiteljsko rastlino kot gostiteljske mravlje. Vse štiri vrste mravljiščarjev, ki jih najdemo v Evropi (Phengaris arion, Phengaris alcon, Phengaris teleius in Phengaris nausithous), živijo tudi na slovenskem Koroškem. Do sedaj je bilo na tem območju znanih zgolj nekaj lokacij za te vrste. Zaradi pospešene izgube habitatov v zadnjih desetletjih so nekatere poznane lokacije postale neprimerne za njihovo preživetje. V tem članku tako podajamo pregled vseh historičnih podatkov štirih vrst mravljiščarjev v Koroški regiji, poročamo o novo odkritih lokacijah za vrste P. alcon, P. nausithous in P. arion ter potrjujemo ponovne najdbe vrst P. nausithous in P. teleius na eni izmed že znanih lokacij. Obstoječe populacije so izrednega pomena za ohranitev omenjenih vrst v Sloveniji, saj so izolirane od drugih območij razširjenosti v državiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaNacionalni inštitut za biologijo
