Adelphobates castaneoticus é endêmica do Brasil e possui ampla distribuição no estado do Pará e norte de Mato Grosso. A espécie é encontrada na serapilheira de ambientes florestais. Embora possa ser localmente afetada por atividades antrópicas, sua distribuição abriga extensas áreas de florestas bem preservadas, incluindo unidades de conservação. Assim, não há ameaças evidentes que possam colocá-la em risco de extinção. Por essas razões, Adelphobates castaneoticus foi avaliada como Menos Preocupante (LC).

“…Adelphobates castaneoticus is also a small size species, measuring between 18 and 23 mm. It has a black body with small stripes or white spots on the back and yellow or orange bright spots on the dorsal and ventral surfaces of the limbs (Caldwell & Myers 1990, Rodrigues & Azevedo-Ramos 2004b, Lima & Galatti 2011, Camera & Krinski 2014. However, Caldwell & Myers (1990) warned of geographical variation in the color pattern.…”

Adelphobates contains three species, and the inaccurate identification of A. quinquevittatus and the scarcity of records of A. castaneoticus complicate inference of their distributions; the latter species occurs in sympatry with A. galactonotus. Our objective was to revise the distributions of Adelphobates by compiling data and modeling habitat suitability, as range limits may be shaped by landscape features and biotic interactions.We initially analyzed the existence of operational taxonomic units within the nominal species and subsequently inferred the observed and potential distributions, taking into account the possible independent lineages for the three species, and we also generated a molecular timetree to understand the chronology of interspecific diversification events. Adelphobates quinquevittatus was found to have a more easterly distribution than previously described, and specimens with phenotypic variation were found to occur in areas inconsistent with the modeling, and A. castaneoticus was concentrated in the Tapajós-Xingu interfluve, surrounded by A. galactonotus. Models indicated that the right bank of the Xingu River is suitable for both species, indeed, both were found there.Despite Adelphobates species having their distributions delimited by major Amazonian rivers, estimated divergence times predate the formation of the modern river network, suggesting that other mechanisms were involved in their diversification.
