A new species of Pristimantis (Amphibia, Anura, Craugastoridae) from the foothills of the Andes in Manu National Park, southeastern Peru

Scientists have identified a new species of Pristimantis frog, Pristimantis pluvialis, in the humid sub-montane forests near Manu National Park, Peru. This discovery was made through detailed morphological and acoustic analysis, distinguishing it from similar species by its unique rostral tubercle, smooth dorsal skin, and advertisement call. The new species, found at elevations of 740 to 1110 meters, differs from Pristimantis lacrimosus and Pristimantis waoranii in size, call frequency, and dorsal coloration. It also contrasts with Pristimantis mendax and Pristimantis olivaceus due to its lack of a sigmoid inner tarsal fold and shagreen skin, respectively. Male specimens measure 21.8–26.9 mm in snout-vent length, while the single female measured 28.8 mm.
