Taxonomists always have had intense discussions about how species should be delimited and recently many studies used integrative approaches by combining molecular, morphological, bioacoustic data. Although these are paramount for understanding diversity, few of them actually formalize delimitations to the final step nomenclatural acts. Historically, Neotropical frog genus Adenomera has been considered as a difficult taxonomic group because it comprises morphologically similar exhibiting high levels intraspecific polymorphism. A recent work using molecular data shed light on phylogenetic relationships within identified several lineages that may correspond undescribed but did not delimit boundaries. In Atlantic Forest, clade formed A. marmorata two putative (Adenomera sp. J K) were identified. this paper, we combine acoustic, in order evaluate limits Forest clade. We provide redescription restrict its type locality Tijuca Massif, Municipality Rio de Janeiro, Brazil. Our results do support candidate diagnosable distinct species. Therefore corresponds with pronounced morphological acoustic variation complex phylogeographic structure.
