This species occurs in two threat-defined locations in southern Aguascalientes and extreme north-eastern Jalisco, Mexico, between 1,800-1,900 m asl. It has an extent of occurrence of 1,017 km2 and an area of occupancy of 432 km2.
Habitat and Ecology
It occurs only in seasonally flooded grasslands, and breeds in both temporary and permanent pools.
It is a rare species and, due to ongoing declines in the quality and extent of its habitat, the population is suspected to be decreasing.
The transformation of the original grassland habitat into agricultural land, and the subsequent pollution from pesticides are major threats to this species. Urbanization is also a threat.
This species is listed as "Threatened" (Amenazada) by the Mexican government. 3% of the species' range is protected in Sierra de Lobos (a state natural protected area), in Guanajuato. Within this area, sustainable practices of agriculture and forest use are being implemented and the area management program includes the establishment of nursery gardens, reforestation activities and species reintroduction ( P.A. Caballero pers. comm. August 2015).
Urgent protection of the original habitat of this species is required (especially in Aguascalientes where only a small area of suitable habitat remains).
Red List Status
Listed as Endangered because its extent of occurrence is 1,017 km2, its area of occupancy is 432 km2, it occurs in two threat-defined locations and there is a continuing decline in the extent and quality of its habitat in southern Agusacalientes and extreme northeastern Jalisco, Mexico.
This species was previously included in the genus Pternohyla which was synonymized with Smilisca (Faivovich et al. 2005).
