Lepidagathis dalzelliana sp. nov., (Acanthaceae: Barlerieae), is described from Maharashtra, India. The new species is closely allied to Lepidagathis clavata Dalzell. in appearance, but differs by long lanceolate, hairy bracts, and spatulate, oblanceolate to ovate-lanceolate glabrous leaves. Colored photographs and notes are provided to facilitate its distinction from closely allied species. In addition, we have designated the lectotype for the name Lepidagathis prostrata Dalzell.
Key words: Acanthaceae, India, Plateau, Barlerieae
