Abstract: We describe a new species of treefrog of the Scinax ruber clade related to Scinax fuscomarginatus from southwest of the state of Goia´s in central Brazil. The new species is characterized by its small size (snout–vent length of males, 15.9–18.6 mm; females, 18.1–18.7 mm), very slender body, a snout that is strongly acute in lateral view and subelliptical in dorsal view, two lateral broad blackish stripes from the posterior corner of the eye to inguinal region, reduced toe webbing, and advertisement calls that are a single pulsed note with a pulse period of 2–13 ms and a dominant frequency of 2.51–5.95 kHz. Vocalizations of the new species and S. fuscomarginatus, Scinax parkeri, Scinax squalirostris, and Scinax wandae are provided and discussed.

Abstract: We describe the external morphology of the tadpole of the frog Physalaemus moreirae. We also provide a review of internal oral features, chondrocrania, and a characterization of the genus based on larval traits. The internal oral features and the external morphology of P. moreirae are most similar to P. jordanensis, a species allocated to the P. gracilis group. None of the larval traits supports the current intrageneric arrangement of species, because several features are shared by species belonging to different species groups. We argue for the inclusion of larval traits in future phylogenetic studies in order to understand the evolution of larval characters.

Abstract: 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.
