Craugastor cyanochthebius is known from San Isidro, on the western flanks of Montaña del Cerro Azul, Sierra del Espíritu Santo, Departament of Copán, Honduras. The locality is at approximately 15 07' 38.2" N, 88 56' 13.8" W and the species was found between 900 and 1,200 masl (McCranie and Smith, 2006).
Habitat and Ecology
The species is found in Montane Subtropical (Premontane) habitats. Individuals have been found between 1730–1930 hours sitting on low vegetation (ca 0.25–1.00 m above the ground) in an area of karstic limestone outcropping during foggy and light rainy conditions. Craugastor charadra is also present at the locality (McCranie and Smith, 2006).
The species was described from seven specimens. It is considered to be a common species (J.R. McCranie, pers. comm. 2008).
The original vegetation in the San Isidro area has been heavily denuded and is now largely taken over by coffee and crop fields. However, the rugged nature of the isolated karstic limestone areas in the region has allowed their associated vegetation to remain largely intact (McCranie and Smith, 2006).
This species' type locality is close (within 2 km) of Parque Nacional Cerro Azul (J.R. McCranie, pers. comm. 2008).
In the Craugastor alfredi group. Craugastor cyanochthebius differs from all other species in the group by a combination of morphological characters (McCranie and Smith, 2006).
