Homalomena lingua-felis is newly described from Tapanuli (North Sumatra Province, Indonesia). This species resembles H. pexa from which can be easily distinguished by its shorter petiole (2.0–4.5 cm vs. 7.0–12 cm), papillate petiole (vs. densely white-tomentose), elliptic or cordate to ovate leaf shape (vs. oblong- to ovate-cordiform), papillate abaxial leaf surface (vs. sparsely hairy), papillate veins (vs. tomentose), papillate peduncle and spathe (vs. tomentose), pendulous peduncle (vs. semi-erect to declinate), and conical staminate flower zone (vs. ellipsoid). This novelty represents a continuation of discoveries on hairy Homalomena in Sumatra.
