is a small anuran species that differs from pipoids by having well-developed mentomeckelian bones and a T-shaped parasphenoid, and shares with neobatrachians features like the presence of a neopalatine, eightprocoelouspresacralvertebrae, roundedsacraldiapophyses, and the lack of free ribs. The new species can be distinguished from other fossil and living neobatrachians by the presence of the following combination of characteristics (autapomorphies marked with an asterisk): azygous frontoparietal bearing ornamentations in form of shallow grooves and two laterally projected and rounded supraorbital flanges*; tectal roofing of

and arranged obliquely in relation to the sagittal plane of the skull. There is no medial contact between them, and they are positioned at the same level in relation to the anterior tip of the maxilla, but both conditions could not reflect the exact morphology of the fossil, as they could be also related to shifts that occurred during the fossilization process. Due to their damaged condition at the lateral margins, the exact morphology of this portion is uncertain. Their dorsal surface is smooth, without ornamentations. The nasals also bear pointed maxillary processes that project laterally, and the posterior margins of such processes contribute to the anterior margin of the orbits. The posterior portion of the nasal maxillary process abuts the maxilla, near the region in which the maxilla and the palatine articulate. There is no evidence of the contact among nasals with premaxilla, squamosal, or frontoparietal.

The epiotic eminences are high, protrude posterolaterally, and are not covered by the frontoparietal. The occipital artery runs in an open groove located in the otoccipital. The occipital condyles are distinct and well separated from each other, with no confluence between them.

In ventral view, the surface of the ilial body is smooth, and there is no sign of a spiral groove. The ischium bears a well-developed posterodorsal region, which has a quadrangular outline, whereas its portion located posterior to the acetabular fossa is short and has a relatively straight margin. The portion of the pubis located below the acetabular fossa is short, except for the region next to the ventral acetabular expansion, which is elongated and forms a rounded projection oriented anteroventrally.
