Bokermannohyla vulcaniae
Bokermannohyla vulcaniae is a treefrog in the family Hylidae (order Anura), recorded as Endangered and tied to Brazil.
Appearance
Bokermannohyla vulcaniae is a medium-sized tree frog, about 40–53 mm (1.6–2.1 in) in snout–vent length. It has brown dorsum, becoming paler ventrally.
Tadpoles of Gosner stages 26–27 measure 29–38 mm (1.1–1.5 in) in total length, of that the body makes 10–13 mm (0.4–0.5 in).
Range and habitat
Bokermannohyla vulcaniae are known from a gallery forest adjacent to a stream at about 1,000 m (3,300 ft) above sea level (the type locality) and in a temporary swamp at the forest edge at 1,248 m (4,094 ft) asl. In both places, specimens were found in vegetation 0.65–1.5 m (2–5 ft) above the ground. It is endemic to Brazil and only known from the region of its type locality in Poços de Caldas, Minas Gerais state.

Breeding
Calling males and egg sites define most frog field work. A species known from one ridge is as narrow as it sounds.
Eggs and damp skin make amphibians quick to vanish from a drained wetland or a forest stripped of litter.
In crisis
The species was assessed as "endangered" by IUCN in 2023 due to its declining population and small known distribution. The species is especially threatened by agricultural and urban runoff as well as habitat loss related to agricultural and mining activities in the area. Two populations in conservation areas have been found (in the Serra de São Domingos Municipal Park and the Botanical Garden of Poços de Caldas).
Chytrid fungus, collection, and wet-forest loss are the usual pressures on frogs with a high threat category.
