The Corquin Robber Frog (Craugastor anciano) is an extinct species of brittle-belly frog formerly endemic to the ground near streams in premontane and lower montane moists forests of the Cordillera de Celaque mountain range, specifically in the departments of Lempira and Ocotepeque in the country Honduras, between 1,400 and 1,840 meters above sea level within an estimated extent of occurrence of only 97.23 km².


Due to its relation with other Craugastors, it was thought to breed via direct development, with the eggs laid onto the land instead of in the water of the areas.


Discovered in 1988, it was always an extremely rare species in the wild since its discovery, partially due to their living in the mountains and there being a lot of unsuitable habitat between the known locality and the next mountain over; it was also thought to not tolerate habitat disturbance. As of 2019 it was officially declared extinct with a fungal Chytridiomycosis infection (a fungal infection caused by both Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans) to blame as a possible reason, combined with habitat loss.
