Miranda's White-lipped Frog

About the Miranda's White-lipped Frog

Leptodactylus macrosternum is a species of frogs in the family Leptodactylidae. It is found in northern Argentina and adjacent eastern Bolivia, Paraguay, northern Uruguay, and southern and western Brazil. The specific name chaquensis refers to the area of Gran Chaco in Argentina. The common names Cei's white-lipped frog and Miranda's white-lipped frog have been coined for it, although this particular species lacks the light upper lip stripe common in the genus.

Adult males measure 65–94 mm (2.6–3.7 in) and adult females 69–98 mm (2.7–3.9 in) in snout–vent length. No light upper lip stripe is present. The dorsum and the flanks have several well-developed pairs of skin folds. Toes have lateral fringes.

Sexually active males have a pair of keratinized thumb spines. They have three distinct advertisement calls: growls, grunts, and trills, of which the first one is the most frequent. Tadpoles of Gosner stage 36 measure 42 mm (1.7 in) in total length.
