Abstract

Brachycephalus is a frog genus endemic to the Brazilian Atlantic Forest and characterized by the bright yellow-orange aposematic colors and the high degree of miniaturization. Herein, we describe a new species of Brachycephalus from Serra do Brigadeiro, Municipality of Ervália, Minas Gerais State, southeastern Brazil. Specimens were collected at high altitudes (i.e., 1266–1498 m above sea level) amidst the leaf litter. The new species is characterized by the presence of black connective tissue covering all dorsal muscles, body completely yellow-orange in life, presence of skull and post-cranial plates, large size (SVL of adults: 14.8–18.5 mm), bufoniform body, absence of metacarpal and metatarsal tubercles, and presence of harmonics in its advertisement call.
