Monitoring helminths in rare and endemic species is crucial, as infections can contribute to population declines. The Sumatran elephant (\n                    <jats:italic>Elephas maximus sumatranus<\/jats:italic>\n                    ), a subspecies of the Asian elephant, is native exclusively to the island of Sumatra, Indonesia. The studies on nematodes of Sumatran elephants remain limited. In this study, three cyathostomine nematodes not previously reported from Indonesia \u2013\n                    <jats:italic>Quilonia renniei<\/jats:italic>\n                    ,\n                    <jats:italic>Murshidia (Murshidia) falcifera<\/jats:italic>\n                    , and\n                    <jats:italic>M.

This approach enabled the observation of previously unreported morphological features of taxonomic significance and corrected existing errors.
