Physalaemus barrioi is a small frog (26.2 mm SVL) belonging to the P. gracilis species group (sensu Nascimento et al., 2005). Body elliptical. Head triangular, longer than wide. Snout sub-elliptical in dorsal view and acuminate in lateral view. Maxillary teeth present. A large subgular vocal sac longitudinally folded. Vocal slits present. Tympanum concealed. Supratympanic fold poorly developed. Dorsum with glands arranged in longitudinal folds, along with isolated rounded glands. Rounded inguinal glands not prominent. Arms short. Fingers and toes without fringes or webbing. Second finger longer than first. Finger formula: I, IV,II,III. Nuptial excrescences on thumbs. Enlarged rounded subarticular and supernumerary tubercles on hands and feet. Inner and outer metatarsal conical tubercles well developed in hands and feet. Tarsal tubercle present. Finger and toe tips not expanded. Tarsal fold present (see photo). Toes formula: I,II,V,III,IV (Bokermann, 1967; Provete et al., 2012).The iris is golden in the upper portion and brown in lateral and lower portions. The inguinal region has contrasting yellow, red, and black colorations. Ocellus in the inguinal gland black, with thin white outline. A reddish coloration is observed in the inguinal region, outer portion of thigh and inner portion of tibia. In some specimens, the dorsum is uniformly dark green instead of dark brown (Provete et al. 2012).The advertisement call is composed of a single, modulated, non-pulsed note with seven harmonics. The mean duration of the advertisement call is 1.24. The minimum frequency is 2.76 Hz, the maximum frequency is 29.14 Hz, the dominant frequency is at the fifth or sixth harmonic. The interval between calls is 0.39 s. Calls are given at a rate of 1.05 calls per minute (Provete et al., 2012).Orton type IV tadpole: exotrophic, lentic, benthic. Body ovoid in dorsal view and globular in lateral view. Snout rounded in dorsal and lateral views. Eyes dorsal, dorsolaterally directed. Nares dorsally directed, small, elliptical, with a large dorsally positioned projection on marginal rim. Spiracle single, short, and sinistral, inner wall with indistinct ridge, positioned on the posterior third of the body, just below the median line of the body. Spiracle opening rounded, its opening posterodorsally directed. Vent tube dextral, right wall displaced dorsally and free from ventral fin. Dorsal fin low, but more extensive than the ventral one, emerging at the point of insertion of the caudal musculature. Caudal musculature reaching the tail tip, which is rounded. Oral apparatus anteroventrally oriented, emarginated laterally. Marginal papillae in a single linear row laterally, in alternating rows ventrally. Marginal papillae absent anterodorsally. Jaw sheaths narrow, strongly keratinized, the upper jaw sheath widely arched, curved. Lower jaw sheath U-shaped, wider than the upper one. Upper and lower jaw sheaths finely serrated. Keratinized labial teeth gently curved toward the oral opening. Labial tooth row formula (LTRF) 2(2)/3(1) (Provete et al., 2012).Provete et al. (2012) provides a thorough description about this species, including karyotype, larval internal oral features and chondrocranium and should be consulted for more details. It also present an extensive review of advertisement call of Physalaemus species.

Distribution and Habitat

The only known population of Physalaemus barrioi occurs in the highlands of the Serra da Bocaina, a segment of the Serra do Mar mountain range in Southeastern Brazil (Provete et al., 2012). Adults of P. barrioi breed in permanent marshes in open areas (Provete et al., 2012).

Apparently, P. barrioi is no longer found in the type locality ("Campo de Fruticultura", currently known as Fazenda Ponte Alta). Specimens occur, however, in other localities within and near the Serra da Bocaina National Park, including Fazenda Bonito (municipality of Arapeí). The type locality has been intensively modified since W. C. A. Bokermann collected the type series (Bokermann 1966). The area was deforested at that time and now supports a secondary forest. Such changes may have resulted in the local extirpation of the species at that location, as currently the species is more commonly found in open montane grasslands in the Serra da Bocaina (Provete et al. 2012).

Males call at night from August to February at the base of small thickets and less often during the day after the heavy rains from October to March. Foam nests are found between September and February anchored at the base of marginal vegetation (Provete et al., 2012). Eggs are white. Tadpoles are commonly found in permanent shallow marshes and small ponds with clay bottoms, in open areas with predominantly herbaceous vegetation from October to April and are active during the day (Provete et al., 2012).

Physalaemus barrioi is a species of frog in the family Leptodactylidae. It is endemic to Serra do Bocaina in São Paulo state, Brazil.[2][3] The specific name barrioi honors Avelino Barrio, a Spanish botanist and zoologist who lived in Argentina.[4] However, the common name Bocaina dwarf frog has been proposed for it.[1][2][4]
Description
Adult males measure 24–29 mm (0.9–1.1 in) in snout–vent length. The head is triangular and longer than it is wide. The snout is sub-elliptical in dorsal view and acuminate laterally. The tympanum is concealed and the supratympanic fold is weakly developed. The fingers and the toes lack fringes and webbing. Coloration is dorsally brown or green, with some patterning that helps to camouflage the animal. A dark stripe runs from the canthus rostralis to the middle of the flank.[3]
The male advertisement call consists of a single, modulated, non-pulsed note lasting about 1.2 seconds. The calls are emitted at a rate of about 8 calls per minute.[3]
Tadpoles have an ovoid body when viewed dorsally and globular when viewed laterally. The body is dark brown and has two dark stripes that continue onto the tail. Gosner stage 37 tadpoles measure about 27 mm (1.1 in) in total length; the body is about 10 mm (0.4 in).[3]
Habitat and conservation
Physalaemus barrioi is a terrestrial species found in forests and grassland at elevations of about 1,200–1,550 m (3,940–5,090 ft) above sea level.[1][3] Males call at night from bases of small thickets in open marsh areas. Foam nests are anchored at the base of marginal vegetation, typically grasses. Tadpoles can be found in permanent shallow marshes and small ponds with clay bottoms.[3]
Physalaemus barrioi occurs within and near the Serra da Bocaina National Park. The species may be negatively affected by reforestation as it is current more commonly found in open montane grasslands.[3]
