Its systematics has rarely been investigated using molecular data, with DNA sequences available for only a few species representing two of the six recognised genera. We collected chalcinotrematine trematodes from freshwater fishes in the Jari River, Amazon Basin, Brazil, and in Misiones, Argentina. Specimens from Brazil were characterised through an integrative approach combining morphological examination with molecular data (partial 28S and ITS2 rDNA sequences), whereas those from Argentina were analysed morphologically. As a result, we describe two new species from Brazil: Chalcinotrema arleneae sp. nov. from Leporinus friderici and Laemolyta proxima, and Unicoelium gerardoi sp. nov. from Hypostomus plecostomus. This study provides the first molecular data for both Chalcinotrema and Unicoelium, expanding the phylogenetic framework of Chalcinotrematinae. Paralecithobotrys brasiliensis is recorded from Argentina in Megaleporinus obtusidens, extending its geographical range. We reassessed the generic limits of Saccocoelioides, the most species-rich genus within the subfamily. Based on combined morphological, molecular, host, and distributional evidence, we propose taxonomic revisions, establishing Neosaccocoelioides gen. nov. for several South American species formerly assigned to Saccocoelioides: N. antonioi comb. nov., N. bacilliformis comb. nov., N. elongatus comb. nov., N. magnus comb. nov., N. miguelmontesi comb. nov. (type species), and N. szidati comb. nov. Additionally, N. platense comb. nov., previously placed in Chalcinotrema, is transferred to the new genus. Saccocoelioides chilkaensis and S. lizae are considered species inquirendae; and S. guaporense is considered incertae sedis. These findings refine chalcinotrematine relationships and highlight the need for expanded molecular datasets to resolve systematic and biogeographical uncertainties.
