Craugastor chrysozetetes
Craugastor chrysozetetes is a possibly extinct species of frog in the family Craugastoridae. It is endemic to Honduras where it is only known from near its type locality on the Cerro Búfalo, Cordillera de Nombre de Dios, at the edge of the Pico Bonito National Park. Common name McCranie's robber frog has been coined for this species. However, himself has argued that this name "should be rejected in favor of a name associated with the type locality instead of a name tied to one of the three authors who named this species".
Description
Adult males measure and adult females in snout–vent length. The snout is nearly rounded in dorsal view and rounded to nearly vertical in lateral view. Tympanum is absent, but there is a well-developed supra-tympanic fold. The fingers bear later keels and broadly expanded discs but have no webbing. The toes bear broadly expanded discs and have webbing, with lateral fleshy fringes in the non-webbed parts. Skin is variously wrinkled and bears many tubercles. The dorsal surfaces are dark olive brown and blotched with pale olive brown or mottled olive-green and dark olive-green. The ventral surfaces of the body and throat are pale purple to purplish brown with dull white flecking on the chin and pale blue flecking on the chest.Craugastor chrysozetetes appears to have been able to form hybrids with Craugastor fecundus.
Habitat and conservation
Its natural habitat was premontane wet forest at elevations of above sea level. It occurred along the stream Quebrada de Oro. It was always a rare species, and after several visits to the only known site failed to locate the species, the International Union for Conservation of Nature assessed it as extinct in 2004. The cause of extinction is thought have been habitat loss and change. Chytridiomycosis might also have played a role. However, this was changed to Critically Endangered in 2019 following the possibility that it may survive within Pico Bonito National Park.Craugastor chryzetetes primarily resides in specific regions within Central America, where it thrives in certain environmental conditions. The species is known to inhabit tropical and subtropical forests, particularly in Honduras and Costa Rica. Its habitat preferences include areas of high humidity, moderate temperatures, and access to leaf litter or rocky crevices for shelter.
