Adult morphology Body very stout, with forelegs and hindlegs short. Snout-vent of about 55 mm. Head high, narrower than in Ceratophrys, rounded when seen from above, slightlv truncate in profile. It is contained twice and 1/2 in the body length. Vomerine teeth in two small round patches, on the inner anterior border of the choanae. Tongue wide, circular, free behind, about 4/5 as wide as mouth-opening. Interocular distance narrower than upper eyelid and equal to the internarinal jnterval. Eye large, prominent, its diameter larger than the interocular distance and equal to the interval between the eye and the tip of snout. Nostrils opening superiorly, at the same distance between the eye and the tip of snout. Tympanum small, its diameter less than 1 J2 of the eye diameter. Fingers slightly fringed; toes about 1/2 webbed. Large, rounded metacarpal tubercles; the inner metatarsal tubercle very large, black and spadelike; the outer metatarsal tuberde very faint, almost indistinguishable. Subarticular tubercles small, rounded. Tarsal fold weak. Foreleg reaching about the groin the tip of the third finger. Hindleg stout: when is adpressed, heel reaches the shoulder. Dorsal skin widely granular, poorly ossified and ornated on the cephalic region. Dorsally also sharp-edged, fine glandular ridges, emphasizing the centers of several. dark spots, scattered minute granules. Ventrally closely granular. No flabby appendix on the glandulous upper eyelid. Arms and legs smooth. No evidence of external vocal sac. Dorsal color whitish or grayish, scattered with enlarged brown or greenish spots, arranged in matched pairs along a light vertebral line. Ventrally whitish: throat spotted, belly immaculate. Larval morphology In Stage 37 (Gosner, 1960), the large tadpole has a slightly depressed body that is cordiform in dorsal aspect, longer than wider, and represents half the total length. Maximum width is at the middle of the body. Snout is gently curved in lateral profile and rounded in dorsal view. Nostrils are rounded, protuberant, and placed in dorsolateral position. Eyes are dorsolateral and well separated. Spiracle is sinistral, short, and positioned on anterior half of body. Vent tube is short, cylindrical, medial, and separated from the abdominal skin by a fold. Tail length almost equals body length, with a slightly rounded tip. Caudal musculature has poorly defined myotomes. Dorsal and ventral fins are quite symmetrical. Dorsal fin arises from the trunk, just anterior to the origin of caudal musculature. Oral disc anteroventral with anterior labium visible in dorsal view; the oral disc is slightly emarginated. A single and continuous row of marginal papillae surrounds the oral disc. Marginal papillae have wide bases and rounded tips and are well separated individually. Few submarginal papillae are placed in the area of lateroventral constriction. Jaw sheaths well keratinized and pigmented, strongly serrated; upper jaw sheath forming a narrow U-shaped arc; lower jaw sheath V-shaped with more developed serrations. Labial tooth row formula is 2(2)/3(1). Labial teeth are long, curved, with distal tips hook-shaped. Neuromasts are only visible under magnification. Four pairs of neuromast lines are present: supraorbital (So), infraorbital (Io), angular (An), and oral (Or) that form, with the oral longitudinal line (Lor) and preorbital line (Pro), the Anterior Lateral Line System. These lines are symmetrical on both sides of the head. The preorbital line crosses over the eyelids, runs between the nostrils, and ends at the upper labium, it is continuous with the supraorbital line. The supraorbital line descends to join the infraorbital line towards the lateral margin of the oral disc whereas the angular line arises below the eye and is continuous with the supraorbital line and extends ventrally. The longitudinal oral line diverges from the angular line and is oriented towards the lateral constriction of oral disc. The oral line originates from the longitudinal oral line and is directed ventrally to end near the angular line. The Posterior Lateral Line System is formed by dorsal (D), medial (M), and ventral (V) lines, which also are paired and symmetrical. The dorsal line arises behind the otic capsule and extends to meet the opposite one at the origin of dorsal fin. The medial line runs below the dorsal line and extends laterally towards the anterior half of caudal musculature. The ventral lines are symmetrical; the left one originating in front of the spiracle and orients ventrally to end near the hind limbs in other species the spiracle interrupts the left ventral line. The supralabial line and auditive patches of the neuromasts are absent. Coloration in life: tadpoles have a brownish-gray dorsum, with a darker hue around the nostrils. Ventral surface of body is unpigmented, with internal organs visible. Caudal epaxial musculature is densely pigmented with stellate melanophores found along the inferior border of hypaxial musculature. Dorsal and ventral fins are transparent, with a few isolated melanophores. Iris is yellowish with dark spots around the rhomboidal pupil. Coloration in preservative: pigmented areas become uniformly darker. Intraspecific variation: The most noticeable character of is the nasal appendix. Its occurrence is variable and appears less frequently as larval development progresses. Most, but not all, tadpoles at Stage 30 have a well-developed nasal appendix. After Stage 30, the appendix is less frequent in occurrence and it is absent in most individuals after Stages 37 and 38. The nasal appendix is found between and in front of the nostrils, it is longer than wide and transparent, protruding anteriorly and varying in length among specimens in the same stage.

Chacophrys pierottii, the Chaco horned frog or lesser Chini frog, is a species of frog in the family Ceratophryidae. It is monotypic within the genus Chacophrys. It is found in the Chaco of northern Argentina, eastern Bolivia, and western Paraguay. Its natural habitats are dry shrubland and gallery forest. Outside the breeding season adults remain buried underground but emerge during the first heavy rains to breed in temporary ponds.

It is threatened by habitat loss caused by agriculture and wood extraction. It is also collected for pet trade.

El escuercito chaqueño (Chacophrys pierottii) es la única especie del género monotípico Chacophrys Reig & Limeses, 1963, perteneciente a la familia de anfibios Ceratophryidae. Es un taxón endémico del Gran Chaco en el centro de Sudamérica.

Chacophrys pierottii, unique représentant du genre Chacophrys, est une espèce d'amphibiens de la famille des Ceratophryidae.

Chacophrys pierottii is een kikker uit de familie Ceratophryidae. De soort werd voor het eerst wetenschappelijk beschreven door Jehan Vellard in 1948. Oorspronkelijk werd de naam Ceratophrys pierottii gebruikt. Het is de enige soort uit het geslacht Chacophrys.

Chacophrys pierottii là một loài ếch trong họ Leptodactylidae. Chúng là đại diện duy nhất của chi Chacophrys, được tìm thấy ở Argentina, Bolivia, và Paraguay. Loài này không bị đe dọa tuyệt chủng.

Các môi trường sống tự nhiên của chúng là các khu rừng khô nhiệt đới hoặc cận nhiệt đới, vùng đất có cây bụi nhiệt đới hoặc cận nhiệt đới, và đầm nước ngọt có nước theo mùa. Loài này đang bị đe dọa do mất nơi sống.
