Lasianthus agasthyamalayanus R. Jagad., S.P. Mathew, Gangapr. & E.S.S. Kumar (Rubiaceae) from the southern Western Ghats, Kerala, India is described as a new species. It resembles especially L. obliquus, but differs from it by having glabrous mature branches; smaller leaves with apiculate apex; triangular, broadly ovate stipules; larger flowers; elliptic-lanceolate calyx lobes, and a black mature fruit. A key to the species of Lasianthus from the southern Western Ghats is provided.
