Head in the clouds: a new dwarf frog species of the Physalaemus signifer clade (Leptodactylidae, Leiuperinae) from the top of the Brazilian Atlantic Forest

In an elevational gradient, the mountain top generally presents a reduced species diversity. However, it is there where we often find microendemic and quite still undescribed species. That prediction very common in underexplored Neotropical mountains, like those of Caparaó National Park – protected area that includes highest peak Atlantic Forest, megadiverse domain. Up its top, found dwarf frog genus Physalaemus (Anura, Leptodactylidae, Leiuperinae), belonging to P. signifer clade. After integrative (morphological, bioacoustical, genetic) analysis, were able describe as new be sister maculiventris. Due restricted distribution at site with extreme environmental conditions (which fires frosts) current instability national policy, suggest this classified endangered A brief description natural history itself will now enable proper conservation status categorization future planning for actions.
