Impatiens theuerkaufiana, a new scapigerous species of Impatiens (Balsaminaceae) from Wayanad district, Kerala, India is described and illustrated. It differs from I. dendricola by having entire lateral sepals, a transversely elliptic, bilobed dorsal petal with wavy margins, a short straight spur less than 5 mm long, and tuberculate seeds; from I. agumbeana by having pendulous linear lanceolate leaves, shorter pedicels up to 3.5 cm long, non-auricled lateral united petals, and an ellipsoid capsule; and from I. stocksii by having long petioles of 5–8 cm, an elliptic lanceolate leaf lamina, long pedicels of 2.0–3.5 cm, and a pouch-like short spur.
