RESUMEN
This study addresses the report of Psoralges libertus mite infestations in Southern Tamandua (Tamandua tetradactyla) after a 127-year gap in the literature, detailing clinical conditions, histopathological findings, and mite identification via morphology. The research broadens our understanding of mite habitats, highlighting challenges in managing parasitic health in free-ranging and captive animals. It underscores the importance of ongoing surveillance for conservation and public health, including potential zoonotic concerns. A P. libertus report in T. tetradactyla after over a century highlights the scarcity of publications on mite-induced mange in this mammalian species. Investigating potential P. libertus' impacts on tamanduas' well-being necessitates further research, particularly regarding pathogenicity, agent epidemiology, and host interaction. This study enhances our comprehension of parasite-host interactions and their relevance to wildlife conservation.
