Here, we provide a review of the morphological characters for both species and synonymize of the species Trombewingia brasiliensisGoff and Gettinger, 1991 with S. lasiurus. Additionally, we provide new locality records for both species and the first record for S. dietzi on southeastern four-eyed opossum, Philander frenatus Olfers, 1818 (Didelphimorphia, Didelphidae).1717-1724engchigger mitesDidelphimorphiaectoparasitesRodentiataxonomyArtigo10.1093/jme/tjab0412-s2.0-85109802304
