Craugastor monnichorum

Craugastor monnichorum is a species of frog in the family Craugastoridae. It is endemic to the mountains of western Panama in the Chiriquí Province;[1][2][4] the type locality is on the slope of Volcán Barú.[3] The specific name monnichorum honors the Monniche family, owners of the property where the type series was collected.[3][5] However, the common name coined for this species, Dunn's robber frog, refers instead to the scientist who described the species, Emmett Reid Dunn.[1][2][4][5]

Description

Adult males measure at least 45 mm (1.8 in) and adult females 61 mm (2.4 in) in snout–vent length.[3][4] The snout is flat and broad. The tympanum is small (especially in females) but visible. Supratympanic and dorsolater folds are present. The finger and toe discs are well-developed, and the two outermost finger discs are particularly large. The toes have basal webbing. Dorsal coloration in adults is dark brown[3] with considerable variation in shade and patterns between individuals.[6]

Habitat and conservation

Craugastor monnichorum occurs in humid montane forests at elevations of about 1,400–1,830 m (4,590–6,000 ft) above sea level.[1][6] It can be found on the ground, rocks, and in low vegetation.[1][3][6] The development is direct (i.e., there is no free-living larval stage). The main threat to this species presumably is habitat loss (deforestation). It is present in the Volcán Barú National Park and the La Amistad International Park.[1]
