The Tadpole and Vocalizations of Hypsiboas polytaenius (Cope, 1870) (Anura, Hylidae, Hylinae)

ABSTRACT. Herein we describe the tadpole and vocalizations of H. polytaenius (Cope, 1870) from populations of the Quadrilataro Ferrifero highlands, state of Minas Gerais, southeastern Brazil, and compare them with other species of the H. polytaenius clade and closely related species in the H. pulchellus group. The tadpoles differ from those of other species of the H. polytaenius clade by the shape of the body and snout in dorsal view, the degree of attachment of the spiracle inner wall to the body, and the tooth row formula 2(1,2)/3(1). The major differences from the closely related species in the H. pulchellus group refer to oral disc characteristics. Two types of calls were identified for H. polytaenius: one composed by one pulsed note and the other composed by isolated notes. Nevertheless, a call composed by two pulsed notes, possibly a territorial call, was recorded once. Comparisons of our results with those previously published for H. polytaenius from Estacao Biologica da Boraceia, state of Sao Paul...
