Abstract: This paper describes the external and buccopharyngeal morphology, chondrocranium and cranial muscles in tadpoles of Physalaemus fernandezae. The data are compared with those for other species of Physalaemus to improve the diagnosis of the species group within the genus. Species of the P. biligonigerus group have four infralabial papillae, two semicircular arches of pustulations in a V-shaped pattern on the prenarial arena, 6–8 conical papillae and 40–60 pustulations on the buccal roof arena, four postnarial papillae, a semicircular median ridge, claw-shaped lateral ridges and larval crista parotica with a poorly-developed anterior process. Species of the P. pustulosus group possess four infralabial papillae (shared with the P. biligonigerus group), tooth row formula 2(2)/3, four lingual papillae, two postnarial papillae, twelve conical papillae and 16–20 pustulations on the buccal roof arena, short lateral ridges with rough concave margins and larval crista parotica with a well-developed anterior process and reduced posterior process. Species of the P. cuvieri group present two infralabial papillae, three pustulations and two serrated papillae on the prenarial arena, five pustulations and two serrated papillae on the postnarial arena, four long and bifid papillae and more than 60 pustulations on the buccal roof arena, and lack larval crista parotica. In species of the P. signiferus group both medial and lateral mental gaps are absent, and the tooth row formula is 2(2)/3(1).
