We describe a new species of Torrent Frog, genus Hylodes, from southern and southeastern Brazil. The new species is assigned to the Hylodes nasus species group and is characterized by large size, robust body, distinctly granular dorsolateral surfaces, absence of light dorsolateral stripes, moderate-sized fringe on the outer margin of toe V, and distinct advertisement call with long note duration. The new species is morphologically similar to Hylodes asper but is readily separated from that species by its distinct vocalization and by the shorter fringe on the outer side of toe V. Description of advertisement call and behavioral notes are provided.
