From the IUCN Red List Species Account:


Range Description

Leptodactylus nanus is known from the northern region of the state of Santa Catarina, Brazil (Kwet, 2007) and may also occur in adjacent Paraná (A. Kwet, pers. comm. 2008). It is found from sea level to ca 800 masl (morro do Baú, Mun. Ilhota), perhaps even a bit higher (A. Kwet, pers. comm. 2008).

Habitat and Ecology

Leptodactylus nanus can be found on the slopes leading to the mountains of the Atlantic Forest domain (within the forest and/or close to it), in transitional areas, and in urbanized areas (close to roads, gardens, etc.)(A. Kwet, pers. comm. 2008). The species undergoes all of its ontogenetic development inside foam nests, which are usually laid far from water (Lutz, 1947).


The species appears to be locally abundant, although its geographic distribution is not considered to be overly extensive (A. Kwet, pers. comm. 2008).

Population Trend


Major Threats

No major threats are currently known for this species.

Conservation Actions

The species is known to occur within the Parque Botânico do Morro do Baú (Mun. Ilhota) and Parque dos Nascentes (Blumenau)(A. Kwet, pers. comm. 2008).

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its likely wide distribution, occurrence in an area where its habitats are not significantly threatened, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Taxonomic Notes

In the Leptodactylus marmoratus species group (redescribed as Adenomera nana; Kwet, 2007). The species name was revalidated based on bioacoustic data (Kwet, 2007).
