Abstrakt: Members of the digenean genus Gyrabascus have been reported from bats and rodents in Europe, Southeast Asia, North America, and most recently from the marsupial, Monito del Monte ( Dromiciops gliroides), in the Argentinian part of Patagonia. We have found digeneans belonging to Gyrabascus in a different species of Monito del Monte ( Dromiciops bozinovici) from Chile. This is the first record of Gyrabascus from D. bozinovici and only the second report of Gyrabascus in a marsupial. Although these specimens are morphologically very similar to Gyrabascus dromiciops, we refrained from identifying our material as G. dromiciops due to insufficient specimen quality and the presence of some morphological differences, leaving open the possibility that the specimens from Chile may potentially represent a different, new species. Both morphological characteristics and molecular phylogenetic analysis using partial sequence of nuclear large ribosomal subunit gene (28S) confirmed the systematic position of these specimens and allowed us to discuss their phylogenetic relationships.
