Abstract

We describe a new species of Sphaenorhynchus from highland forest habitats in the Reserva Biologica de Pedra Talhada, an Atlantic Forest remnant of northeastern Brazil. The new species is diagnosed by having a snout-vent length of 24.8-29.3 mm in males and 26.6 mm in the only available female; snout truncate in dorsal view, protruding in lateral view; vocal sac single, subgular, moderately developed, extending to the middle of the pectoral region, longitudinal folds present; dorsolateral black line from the tip of snout extending posteriorly beyond the eye to gradually disappear on the flanks; white glandular subcloacal dermal fold present; vomerine, premaxillary, and maxillary teeth present; and advertisement call with 2-3 pulsed notes (3-6 pulses each) with a duration of 0.19-0.24 s, a frequency range of 526.3-4438.8 Hz, and a dominant frequency of 2250-3000 Hz. It is the eighth species of the genus that occurs in northeastern Brazil. (AU)
