A new species, Lewinskya lamyana F.Lara, Garilleti, Draper & Mazimpaka, is described. It is a mainly epiphytic moss, so far exclusively found in southernmost Spain on the summit area of Sierra Bermeja, a coastal mountain, which is exceptional in several environmental aspects. The new moss is characterized by a set of morphological traits, most of them easily observed: medium to large plants; leaves lanceolate and acuminate with recurved margins; calyptra campanulate with scattered stout hairs; capsule fully immersed, brown, cylindrical, with 8 broad and prominent ribs; exostome of 8 pairs of teeth easily splitting, all fused basally in a continuous low ring; teeth opaque, cream-coloured, recurved to revolute when dry; endostome of 8 hyaline, linear and relatively stout segments; operculum convex to conic, wider than capsule mouth, long rostrate, with a conspicuous red basal rim. The new moss is illustrated and compared to similar taxa.
