Tribe Thylamyini

The thylamyine fauna of the Yavarí-Ucayali interfluve includes Gracilinanus emiliae , a diminutive species of gracile mouse opossum, and at least three species of slender mouse opossums ( Marmosops ). A fourth species of Marmosops could be expected to occur locally, perhaps in the seasonally flooded forests along the right banks of the Ucayali and Amazon rivers, a habitat that remains poorly sampled in our region (appendix 2).
