This article describes a recently extinct new species of Atlantic Forest nurse frog, Dryadobates erythropus . This species description is based on a single, highly desiccated adult male collected in 1963 in Curitiba, Paraná, significantly expanding the known southern distribution of the Dryadobates clade. The authors confirm the specimen's identity through detailed morphological analysis, despite...

This paper investigates the taxonomy of  Atlantic Forest nurse frogs  using  museomics , which involves analyzing  ancient DNA (hDNA)  from museum specimens, alongside  morphological data  and  bioacoustics . Due to  extinctions at type localities , previous studies were unable to obtain sufficient evidence to resolve their systematics, prompting the use of hDNA from  museum collections  to clarif...

This paper, published in  Zootaxa , describes the discovery and formal description of a  new species of frog ,  Neblinaphryne imeri , found in the  Serra do Imeri massif in the Amazonas state of Brazil . Researchers utilized a  multidisciplinary approach , including molecular, morphological, acoustic, osteological, and myological data, to identify and characterize the species. They compare the new...

This article  employs museomics, analyzing historical DNA from museum specimens , to re-evaluate the classification of a group of tree frogs, specifically the  Dendropsophus araguaya  complex, aiming to  resolve issues of taxonomic uncertainty . By successfully extracting and sequencing DNA from preserved individuals of  D. rhea  and  D. tritaeniatus , the researchers  determined their evolutionar...

This research paper  investigates the taxonomic status of the Boana cymbalum frog, considered extinct since the 1960s, by utilizing historical DNA (hDNA) extracted from a preserved museum specimen . Through advanced sequencing techniques, the study successfully  places B. cymbalum within the B. pulchella group  phylogenetically, confirming its distinctiveness from closely related species like  B....
