Boana latistriata

Adult males measure 35–41 mm (1.4–1.6 in)[3][4] and adult females 41–52 mm (1.6–2.0 in) in snout–vent length. The tympanum is distinct. Finger and toe tips bear adhesive discs; fingers have traces of webbing while the toes are moderately webbed. The dorsum has a characteristic pattern consisting of four wide, light brown longitudinal stripes interspersed by three narrow brown stripes. The flanks have a dark brown lateral stripe delimited by a white line above and by a narrow white stripe below. Males have a subgular vocal sac.[3]

Tadpoles of Gosner stage 25 measure about 42 mm (1.7 in) in total length, including the 14 mm (0.6 in) body. The tadpoles reach a total length of 64 mm (2.5 in) at Gosner stage 39, including the 21 mm (0.8 in) body. The tail fin is higher than the body.[5]

Males call from dusk to late at night (at least to 2 am), perched on shrubs and grass, near or above the water. They have two types of advertisement calls: a short, single-note call with a lower pulse period, and a long call with higher pulse period. Calling males may engage in fights.[4]

Boana latistriata occurs in montane Atlantic forest and highland grasslands at elevations of 1,200–2,450 m (3,940–8,040 ft) above sea level.[1][5] The tadpoles develop in rivulets[1][5] and are benthic, probably feeding on organic matter.[5]

This species is threatened by deforestation and fragmentation of the Atlantic forest habitat.[1] It is present in the Itatiaia National Park.[1][5]
