Arabis (sect. Drabopsis) lycia is described as a species new to science and illustrated, and its taxonomic position close to A. bryoides of the S Balkans is discussed. SEM micrographs of the indumentum of A. lycia and its relatives (A. bryoides, A. carduchorum, A. drabiformis) are presented and their ecological requirements outlined. The new species is a subalpine cushion-forming plant of shaded vertical limestone rocks along the ridge of the Bakirli Daği in the eastern part of the Western Taurus in Turkey. The chasmophytic habit and its stenochory suggests that A. lycia should be included in the list of relic endemics known from the mountains W of the Bay of Antalya.
