This species is known only from Hacienda Espinosa, at about 350m asl, 9km west of Santo Domingo de los Colorados, in the province of Pichincha in north-western Ecuador.
Habitat and Ecology
If it still occurs, this species is presumably found in lowland forest. There is no reliable information on its breeding habits, although the larvae are presumably deposited in water for their development, as with other species of the genus.
The population status of this species is not known, and it might have disappeared from the type locality as a result of the complete alteration of this area.
The major threats to this species are logging and the invasive species Rana catesbeiana.
The range of Epipedobates espinosai does not include any protected areas, and it might no longer occur in the type locality, which has been completely altered. It is listed on CITES Appendix II.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity as well as absence of recent information on its extent of occurrence, status and ecological requirements.
The taxonomic status of this species is unclear. It seems to be a junior synonym of Epipedobates boulengeri (Coloma pers. comm.), which itself might be a complex of more than one species.
