Calceolaria molaui Puppo, sp. nov. is described and illustrated. The new species was collected in Loja, in disturbed paramos near the frontier with Peru so it would be expected to occur in northern Peru as well. It is characteristic for having hirsute indumentum composed of branched trichomes, ovate, subcoriaceous leaves with reticulate venation, cyme bracts absent, elaiophore absent, and brown, deflexed anthers, totally dehiscent. Due to its indumentum, leave shape, and anther morphology, C. molaui is placed in Section Lehmannina Pennell within subgenus Calceolaria. This is the only species of this section in southern Ecuador.
