In addition to genetic differences, the new species is diagnosed by its small size, white or pale ventral coloration on the thighs in life, white ventral coloration in males in life, posteriorly diffuse ventrolateral stripe in females in life, presence of webbing between toes II and III, and absence of isolated advertisement calls. Progressive habitat loss at the type locality has resulted in a 30% reduction in the forest fragment at the type locality from 0.543 km\u00b2 in 2011 to 0.384 km\u00b2 in 2025. We surveyed another forest fragment near the type locality but failed to detect additional individuals, leading us to classify the new species as Critically Endangered due to its extremely limited distribution (&lt; 1 km\u00b2) and ongoing anthropogenic pressure at the type locality. We also reanalyzed the advertisement calls of D. alagoanus to enable comparisons, finding that it produces notes emitted both in isolation and groups.<\/jats:p>","DOI":"10.11646\/zootaxa.5845.2.6","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T01:07:15Z","timestamp":1783300035000},"page":"319-339","source":"Crossref","is-referenced-by-count":0,"title":["A critically endangered new species of Dryadobates (Anura: Aromobatidae) from Esp\u00edrito Santo, Brazil"],"prefix":"10.11646","volume":"5845","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9596-9361","authenticated-orcid":false,"given":"MAX HIDEKI OLIVEIRA","family":"HOMMA","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7004-3915","authenticated-orcid":false,"given":"KATARINE NOGUEIRA","family":"NORBERTINO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1726-999X","authenticated-orcid":false,"given":"TARAN","family":"GRANT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4913","published-online":{"date-parts":[[2026,7,6]]},"container-title":["Zootaxa"],"original-title":[],"link":[{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.5845.2.6\/59471","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.5845.2.6\/59471","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T01:07:15Z","timestamp":1783300035000},"score":1,"resource":{"primary":{"URL":"https:\/\/mapress.com\/zt\/article\/view\/zootaxa.5845.2.6"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,7,6]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2026,7,6]]}},"URL":"https:\/\/doi.org\/10.11646\/zootaxa.5845.2.6","relation":{},"ISSN":["1175-5334","1175-5326"],"issn-type":[{"value":"1175-5334","type":"electronic"},{"value":"1175-5326","type":"print"}],"subject":[],"published":{"date-parts":[[2026,7,6]]}}}
