A new species of Lejeuneaceae from Cerro de la Neblina in Venezuela, Cheilolejeunea neblinensis, is described and illustrated. The species is easily recognized by the row of enlarged cells along the lobule keel, a unique feature that has not been observed in any other species of Lejeuneaceae. Further diagnostic characters include the asymmetrically oblong and slightly falcate leaf lobe, the ovate-triangular lobule with the free margin curved downwards towards the narrow apex, the presence of two closely associated teeth at the lobule apex, and the gynoecia on elongated branches with 1(-2) pycnolejeuneoid innovations. By its lobule apex the new species resembles C. decurviloba (Steph.) X.-L. He and the taxa formerly placed in Trachylejeunea s.str. Differences between these species are discussed.
