Zusammenfassung:	The Paraná region of eastern Paraguay is highlighted as the centre of a radiation in Ipomoea species, of which I. malvaeoides is the best known and arguably the most variable. A key to frequently confused Paraguayan species in this complex is provided. A new species, I. itapuaensis J. R. I. Wood & R. Degen is described and I. malpighipila O'Donell var. aemilii O'Donell is raised to specific status as I. aemilii (O'Donell) J. R. I. Wood & R Degen. The two species are illustrated and their characteristics, distribution and conservation status are discussed.
