fornecido por AmphibiaWeb articles
This recently described species belongs to the H. polytaenius clade, within the H. pulchellus group (Faivovich et al. 2005), in the H. polytaenia species group according to the original description (Caramaschi and Cruz 2004). It is relatively small for the group (males 24-29 mm, females 33-34 mm SVL). The head is narrow and the body is elongated. Like other members of the H. polytaenius clade, it possesses a dorsal pattern composed of brown stripes. The snout is rounded in dorsal view. Eyes lateral and prominent. Single, developed vocal sac. Tympanum is rounded and a small, supratympanic fold is visible, reaching the arm. Dorsal surface smooth; belly and ventral surface of the thigh with granulations. A single large prepollex is present, with a curved spine. Finger discs small. Metatarsal tubercles small. This frog bears a supracloacal crest but the calcaneous appendix is absent.The epithet of this species was given in honor of the Prof. Johann Becker.

Distribution and Habitat

fornecido por AmphibiaWeb articles
Found in SE Brazil, in southern Minas Gerais state. Until 2006 this species was known only from the type locality in Poços de Caldas, 1,200 m a.s.l. Its distribution has since been extended about 120 Km ESE, to the municipality of Pedralva (Orrico and Luna-Dias Neto 2006). H. beckeri is also known from Lambari, Carrancas and São Tomé das Letras (Acioli and Toledo 2008) another locality in Minas Gerais state. The species is more commonly found on rainy days, in open areas, near small permanent rivulets or temporary ponds with marginal vegetation composed of Poaceae and Cyperaceae, and small bushes, and less commonly at the forest edge (pers. obs.).

Males of this species call at night from low vegetation. It is found at low density, after heavy rains, and only in the rainy season. Few specimens were collected between September and March (Caramaschi and Cruz 2004; Orrico and Luna-Dias Neto 2006, pers. obs.). It is likely that the reproductive mode is similar to other members of the H. polytaenius clade with eggs and exotrophic tadpoles in lentic water, that is, reproductive mode 1 of Haddad and Prado (2005). More detailed data on life history, abundance, and calling activity are needed to correctly assess the conservation status of this species. Tadpoles are unknown, though their ecology could be similar to other members of the H. polytaenius clade (see also the recent review of tadpoles of the genus Hypsiboas in Kolenc et al. (2008) with the general characterization of the tadpoles of the H. pulchellus species group). The advertisement call was recently described by Acioli and Toledo (2008): the call is given sporadically, and composed of 2 notes; the first note is longer and has more pulses than the second note, which may be emitted or not.

Its range is within at least one protected area (the Parque Estadual Nova Baden, at Lambari-MG). Population fluctuations seem to be common.

Boana beckeri
(

fornecido por wikipedia EN
Boana beckeri is a species of frog in the family Hylidae. It is endemic to Brazil and is only known from a handful of localities in southern Minas Gerais and adjacent northeastern São Paulo.[3][4] The specific name beckeri honors Johann Becker, Brazilian zoologist[2][5] who collected many of the types.[2]
Description
Adult males measure 24–29 mm (0.9–1.1 in) and adult females 32–34 mm (1.3–1.3 in) in snout–vent length. The tympanum is distinct. The eyes are prominent. The fingers and toes bear terminal discs and are partially webbed. The dorsum has four narrow longitudinal light brown stripes, intercalated by three brown stripes outlined by a cream line. There is also a pair of dark brown lateral stripes, delimited by a white-silvery line above and by a narrow white-silvery stripe below. Males have a single subgular vocal sac.[2]
There are two types of male advertisement calls. Type "a" call is "harsh" call consisting of a single pulsed note. Type "b" call is a trill of unpulsed notes.[6][4]
Habitat and conservation
Boana beckeri occurs in montane Atlantic forest[1] or remnants thereof at elevations of 830–1,290 m (2,720–4,230 ft) above sea level. Males have been observed calling during nighttime perched on bushes or grasses at the margins of small streams and ponds.[6][4] It appears to be locally common.[4] As of late 2020, the listing of this species in the IUCN Red List of Threatened Species dates from 2006 when it was only known from a single population. At the time, Boana beckeri was considered "data deficient".[1]
