Sinningia lutea (Gesneriaceae) is described and illustrated as a new species from the Pampa Biome, in Southern Brazil. In the literature, this species has hitherto been confused with S. allagophylla from which it can be easily separated using a set of floral and vegetative features (especially corolla color and size and leaf shape). An artificial key to separate S. lutea from S. allagophylla and S. curtiflora (another sympatric species, with some morphological similarities) is presented. Some ecological remarks on the differential distribution of S. lutea and S. allagophylla are also made.
