摘要

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.

Bozinovici的Gyrabascus的第一次记录,只有Massupial的第二次报告Gyrabascus。虽然这些标本与Gyrabascus Dromiciops非常相似,但由于样品质量不足和存在一些形态差异,我们不鉴定我们的材料作为G. Dromiciops。智利的标本可能代表不同,新的可能性物种。使用部分核大核糖体亚基基因(28s)部分序列的形态特征和分子系统发育分析证实了这些样本的系统位置,并使我们讨论了它们的系统发育关系。
