Amphibians are threatened by multiple factors, including climate change, habitat loss, and infectious diseases. In Mexico, amphibian declines have been attributed mainly to habitat loss, disease, pollution, and in some cases illegal trafficking of species. Despite evidence of amphibian declines, recent studies have recorded species that had not been found in the wild for many years. We report on the results of fieldwork conducted within individual amphibian-focused projects in the Mexican highlands. Our find- ings include 26 frog species, 23 of them endemic to Mexico, the discovery of five new populations that expand the restricted distributions of three microendemic and one endemic species (Plectrohyla ameiboth- alame, P. cembra, P. cyclada, and P. hazelae, respectively), and the rediscovery of five species that were considered possibly extinct in the wild (P. celata, P. cembra, P. chryses, P. crassa, and P. robertsorum). For each species we report the conservation status (NOM-059 and IUCN Red List), the date of the most recent field observations, and the most recent reference that suggests species declines and/or possible ex- tinctions. Our results show that while some frog species persist in the face of multiple threats, additional fieldwork and conservation efforts should be conducted to monitor these species and help ensure their future persistence in the wild.
