En los laterales del cuerpo se divisa una fina línea blancuzca, acompañada de otra más oscura, que se extienden desde el ojo hacia la parte posterior del cuerpo. En los ejemplares de esta especie también pueden observarse manchas oscuras en la zona de las axilas, la ingle y lado de brazos y patas.

La cabeza es tan larga como ancha, con ojos grandes de pupila horizontal. El timpano es pequeño, pero notable.
Se la encuentra en gran variedad de ambientes, principalmente en lagunas temporarias, zonas cercanas a cuerpos de agua, ceibales, juncales y pajonales. Por lo general son más activas durante la noche y durante el día reposan en ramas y rocas utilizando sus discos adhesivos digitales.
Cambia de color notablemente para pasar desapercibida en el ambiente en que vive.
Artrópodos tales como insectos y arañas, son las presas más usuales de este tipo de anfibio. Se reproduce en lugares de agua permanente durante los meses de Agosto, Noviembre y Diciembre.
