Boana latistriata is a species of frog in the family Hylidae.[1] It is endemic to Brazil and only known from its type locality, Itatiaia National Park, and from Marmelópolis, both in the state of Minas Gerais.[2][3] The specific name latistriata refers to the wide stripes on the back of this frog.[4]

Description

Adult males measure Script error: No such module "convert".[4][3] and adult females Script error: No such module "convert". 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.[4]

Tadpoles of Gosner stage 25 measure about Script error: No such module "convert". in total length, including the Script error: No such module "convert". body. The tadpoles reach a total length of Script error: No such module "convert". at Gosner stage 39, including the Script error: No such module "convert". body. The tail fin is higher than the body.[5]

Reproduction

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.[3]

Habitat and conservation

Boana latistriata occurs in montane Atlantic forest and highland grasslands at elevations of Script error: No such module "convert". above sea level.[2][5] The tadpoles develop in rivulets[2][5] and are benthic, probably feeding on organic matter.[5]

This species is threatened by deforestation and fragmentation of the Atlantic forest habitat.[2] It is present in the Itatiaia National Park.[2][5]
