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. Common name Cei's white-lipped frog has been coined for it, although this particular species lacks the light upper lip stripe common in the genus.

Description

File:Cei's White-lipped Frog (Leptodactylus chaquensis) (48424432392).jpg, Brazil]]

Adult males measure {{convert|65|-|94|mm|in|1|abbr=on}} and adult females {{convert|69|-|98|mm|in|1|abbr=on}} 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 {{convert|42|mm|in|1|abbr=on}} in total length.

Habitat and conservation

Leptodactylus macrosternum is a ground-dwelling species occurring near ponds and flooded areas at elevations below {{convert|1000|m|abbr=on}}. The eggs are deposited in large foam nests over puddles and flooded areas in shallow water (<15 cm deep). Males call from the water's edge or from within the water.{{cite iucn | author = Heyer, R. | author2 = Reichle, S. | author3 = Silvano, D. | author4 = Lavilla, E. | author5 = di Tada, I. |name-list-style=amp | title = Leptodactylus chaquensis | volume= 2004 | page = e.T57118A11583875 | year = 2004 | doi = 10.2305/IUCN.UK.2004.RLTS.T57118A11583875.en }}

This species is common and adapts well to anthropogenic disturbance. It is consumed as food in Argentina, which can lead to local declines. It occurs in several protected areas.
