The genus Vitreorana currently contains eight species,
with distribution in Argentina, Brazil, Colombia, Guyana,
Ecuador, Paraguay and Venezuela (Guayasamin et all.
2009; Frost 2011). In Brazil, the genus is represented
by Vitreorana eurygnatha (Lutz, 1925), Vitreorana
oyampiensis (Lescure, 1975), Vitreorana parvula
(Boulenger, 1895) and Vitreorana uranoscopa (Miller,
1924) (Lima et al. 2005; Guayasamin et al. 2009).

Vitreorana uranoscopa has geographical distribution
in Brazil, Argentina and Paraguay (Heyer 1985; Stetson
2001; Frost 2011; IUCN 2010). The species is endemic
to the Brazilian Atlantic Forest, occurring from the states
of Espirito Santo to Rio Grande do Sul (Heyer 1985;
Garcia and Vinciprova 1998; IUCN 2010). It is usually
found in environments close to streams of clear water
within forested areas (Eterovick et al. 2005; Lucas and
Fortes 2008; Machado et al. 2010). The populations of
V. uranoscopa are in decline (Eterovick et al. 2005; IUCN
2010), and the species is endangered in the states of Rio
Grande do Sul (Fontana et al. 2003), Parana (Segalla and
Langone 2004) and Espirito Santo (SEAMA 2005).

In Rio Grande do Sul, this species is poorly studied,
being recorded to the north region in the municipalities
of Planalto, Rodeio Bonito and Barracao (Garcia and
Vinciprova 2003). Recently, Machado et al. (2010)
expanded the distribution of the species for the eastern
region, in the municipality of Sao Marcos. There is a paucity
of data on its occurrence and on population censuses in Rio
Grande do Sul, so that further studies on its distribution
are needed for an accurate assessment of its conservation
status. Therefore, this study represents a new record of V.
uranoscopa in the state of Rio Grande do Sul (Figure 1).

The study was carried out at the cascade of Maringa
(28°30’S,52°05’W),municipalityofVilaMaria,northeastern
state of Rio Grande do Sul. The area has approximately
3,5 ha and has an interesting phytophysionomic diversity

ABSTRACT: The Atlantic Forest Biome is among the world’s hotspots for biodiversity conservation and concentrates
the greatest diversity of amphibians in the world. However, information on the distribution pattern of species is largely
unknown in this biome. This study report new records of Vitreorana uranoscopa for northeast region of Rio Grande do Sul.

of environments, housing small ecosystems, which are
formed by varying topography and a gradient of ecological
factors such as humidity, temperature and luminosity.
The altitude varies between 528 and 605 m above sea
level. The region has a humid temperate climate with hot
summers (Koppen 1931), average temperature of 16 to
18°C and average annual rainfall between 1600 and 2000
mm, regularly distributed (Rio Grande do Sul 1994). The
local vegetation is the domain of the Atlantic Forest Biome
(IBGE 2010), featuring an enclave of two phytophysionomic
types, the mixed montana forest in the highest parts and
semi-deciduous seasonal forest occupying the slopes and
the valley drained by the Jordao creek, the latter being the
dominant phytophysionomic type.

The record of V. uranoscopa was held in October 2010,
in the banks of the Jordao creek, a tributary of the Guaporé
River, part of the Jacui River basin, one ofthe mostimportant
of the state. On the marginal vegetation we observed five
males in calling activity, two couples in amplexus and one
spawning with 30 eggs (Figure 2). Despite the small size,
the occurrence of V. uranoscopa in the cascade of Maringa
shows the good conservation conditions of the area,
since the requirement of the species to specific habitat
characteristics is well known (Garcia and Vinciprova
2003; Cisneros-Heredia and McDiarmid 2007). The new
record of V. uranoscopa in the northeast of Rio Grande do
Sul, contributes to the knowledge of its distribution in the
state and also to create strategies to protect this species
considered threatened by extinction in the state (Fontana
et al. 2003). Voucher specimens are housed at Colecao
de Anfibios da Universidade Comunitaria da Regido de
Chapecé (CAUC 0988-0989).
