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. [ABSTRACT FROM AUTHOR]

We analyzed variation among Hylodes with nuptial tubercles using morphometrics, vocalization, and external morphology. We identified three species: Hylodes phyllodes from the Serra do Mar, State of São Paulo, and southern portion of the State of Rio de Janeiro; a new species from Ilha Grande, municipality of Angra dos Reis; and a new species from the Serra dos Órgãos, municipality of Guapimirim. The new species are both from the state of Rio de Janeiro, southeastern Brazil. [ABSTRACT FROM AUTHOR]
