Hylodes perere

Hylodes perere is a species of frog in the family Hylodidae. It is endemic to Brazil and only known from Serra Negra, a part of Mantiqueira Mountains, in Santa Bárbara do Monte Verde, Minas Gerais state. The specific name perere (from Portuguese pererê) is derived from a character in Indian folklore who guards the forest, disrupting its silence with its whistles—in reference to the vocalizations of this species.

Description
Males measure 23.4 – and females 23.9 - 28.4 mm in snout–vent length. The snout is truncated in both dorsal and lateral views. The dorsum and dorsal portions of thighs are light olive-brown with dark blotches. There are dark stripes in the thighs.

Males are territorial and call in forest-covered stretches of streams, perched on rocks, branches, stream marginss, or partly submerged in the water. They both day and night; this is unusual as other Hylodes species call by daytime only.

Habitat
The species has been collected by small streams at elevations of 1200 – above sea level in a hilly area covered by seasonal semideciduous forests and dense montane forests.
