We redescribe Hypsiboas semiguttatus (Lutz, 1925) and describe its tadpole and vocalization. We also describe a new species, previously confused with H. semiguttatus from Misiones, Argentina, and potentially from Brazil. This new species differs from H. semiguttatus in being more robust, having a tadpole with complete marginal papillation (no anterior gap), and a labial tooth row formula of 3/5. We discuss the status of populations previously assigned to H. semiguttatus and discuss the relationships of the new species within the Hypsiboas pulchellus group.
