Lessingianthus concepcionis, a new species from northern Paraguay is described and illustrated. The new species has a certain resemblance to L. niederleinii but can be easily separated by the combination of leaves with denticulate and revolute margins, tomentose beneath, involucre with 6?7 series of phyllaries, glandular trichomes on the corolla lobes, and the chromosome number 2n=8x=128.
