Odontophrynus barrioi (vernacular name: Barrio's escuerzo) is a species of frog in the family Odontophrynidae. It is endemic to western Argentina and known from La Rioja, San Juan, and Catamarca Provinces.[2]

Description

Adult males measure 47–69 mm (1.9–2.7 in)[3] and adult females, based on just two specimens in the type series, 54–55 mm (2.1–2.2 in) in snout–vent length.[4] The body is chubby with stout limbs. The head is small and wider than it is long. The canthus rostralis is bluntly rounded. The tympanum is hidden. The fingers have slightly developed fringes, and the toes are slightly webbed. Skin is granular, with scattered, irregularly arranged, rounded glandular warts on dorsally. The parotoid gland are irregular and rounded. Dorsal coloration is brownish with faint lateral and dorsal yellowish longitudinal bands. The warts are darker brown. Ventrally the coloration is bluish or brownish, with scattered white granuli.[4]

The male advertisement call is a trill constituted by a repeated and pulsed note.[3]

Habitat and conservation

Odontophrynus barrioi occurs in montane dry shrublands and nearby rocky outcrops at elevations of 1,450–2,200 m (4,760–7,220 ft) above sea level.[1][4] Breeding takes place in permanent mountain streams; the larval developmental period is long, over a year.[1]

This species is common and stable in suitable habitats, but habitat loss and degradation caused by livestock and firewood extraction are still considered threats to this species.[1]
