Phyllomedusa araguari is currently only known from the type locality: Estação de Pesquisa e Desenvolvimento Ambiental Galheiro (ca 19 12’ S, 47 10’W; 900 masl), municipality of Perdizes, Minas Gerais, Brazil (Giaretta et al., 2007).
Habitat and Ecology
Vegetation types at the type locality include small patches of several Brazilian savanna (Cerrado) physiognomies, including forests and grass fields. Males were found calling during the night along a narrow (0.5 m wide) deep (2 m)
eroded trench (100 m) bordered by short (< 1 m high) dense grass-like vegetation and sparse low (< 2 m high)
shrubs, including Velloziaceae. Tadpoles were found in deep (up to 2.5 m) pools along the trench. The
water of these pools was colored muddy red and was permanently shaded by the marginal bank and bordering
vegetation. One egg clutch found in the month of December 2003 was wrapped in a leaf (Melastomataceae) hanging over a pond. It had 24 eggs with embryos (Gosner stage 21, 21.8 mm TL), and many small (2 mm) jelly spheres. Syntopic frogs include Ameerega flavopicta and Leptodactylus cunicularius (Giaretta et al., 2007).
The species is known from the type series, comprised of three specimens.
The reservation is surrounded by cattle farms, agricultural fields and the lake of a hydroelectric power station (Nova Ponte, MG) in the Araguari River. Given that the new species is a grass/shrub environment dweller, it probably is not threatened of extinction by local human activities such as damming, deforestation, and cattle farming. Potential threats appear to include fires, exotic grasses (Melinis minutiflora Beauv) over-shadowing trenches/ponds, and removal of natural vegetation for agriculture (Giaretta et al., 2007).
The type locality is a research station (Giaretta et al., 2007).
Phyllomedusa araguari differs from other similar species in colour pattern, size, advertisement call and breeding site (Giaretta et al., 2007).
