Abstract
Physalaemus feioi is a South American frog endemic to the Brazilian Atlantic Forest that occurs in the states of Minas Gerais and São Paulo. We evaluated sexual dimorphism, female fertility, and diet of P. feioi from two locations in the state of Minas Gerais, including the type locality of the species. We collected 73 individuals (16 adult females and 57 adult males). The number of oocytes of P. feioi (x̅ = 1385 ±498.13) was higher than in other species of the genus, such as P. maculiventris, P. signifer, P. cuvieri, and P. ephippifer, but it resembles that of P. centralis, P. kroyeri, and P. marmoratus. The prey items with the highest index of importance were Coleoptera (IIR = 24.26) and Formicidae (IIR = 16.46). We found no sex differences regarding the number of ingested prey and the volume of the stomach contents. In summary, Physalaemus feioi was similar to other species of the genus regarding sexual dimorphism, fecundity, and feeding habits.
