The tadpoles of Physalaemus albifrons used in this description were obtained from a pair collected in a permanent pond in Brotas de Macaúbas, state of Bahia, Brazil. The external morphological features are similar to those of other members of the P. albifrons species group, differing by the presence of interruptions in the row of the marginal papillae of the lower lip. Labial tooth row formula is 2(2)/3(1, 2). The internal oral morphology of P. albifrons differed from those of P. marmoratus, P. santafecinus and P. biligonigerus by the presence of three lingual papillae.
