Taxonomic Notes: This species was known as Leptodactylus fragilis for many years until Heyer (1978) determined that L. labialis and L. fragilis represent the same species and that the former was the correct name based on publication priority. However, Heyer (2002) later determined that Leptodactylus fragilis is in fact the valid scientific name for the species.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-10-20
Assessor(s): Ronald Heyer, Andrés Acosta-Galvis, Abraham Mijares, Frank Solís, Roberto Ibáñez, Geoffrey Hammerson, Jay Savage, Larry David Wilson, Federico Bolaños, Gerardo Chaves, Javier Sunyer
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.

Population [top]

Population:It is a widespread and common species in a variety of habitats in the Yucatan Peninsula and vicinity (Lee 2000). In Texas, populations reportedly are sparse but probably stable (Bartlett and Bartlett 1999) or extirpated (Dixon 2000). It is very common in Costa Rica, and is a very common species in South America.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial, nocturnal species found in savannah, grassland, semi-arid lands, and open habitats in humid and dry, lowland and montane tropical forests. It is seen near marshes, ponds, and any temporary lentic body of water, and is common in open and disturbed sites, and also in grasslands, cultivated fields, roadside ditches, and a wide variety of other habitats. It often hides under rocks or in burrows under clumps of grass. It lays its eggs in foam nests whipped from body secretions; foamy masses may be placed in excavations made in ground by male. The larvae live in the watery centre of the foam mass until rains allow them to swim into nearby pools.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is an adaptable species that is facing no major threats. It might be extirpated at the northern periphery of the range in southern Texas due to heavy use of organophosphates (Dixon 1987, 2000).

Conservation Actions [top]

Conservation Actions: It occurs in many protected areas.
