Two observations of the rare marsupial Glironia venusta accompanied by offspring were made in the states of Para and Mato Grosso, Brazil. In December of 2011, a female with three cubs was captured in the municipality of Jacareacanga-PA. In July of 2012, another female, also with three cubs, was observed foraging in a forest matrix in the municipality of Paranaita-MT. It was observed that, just as other neotropical marsupials, G. venusta can present a gummivorous diet on some occasions. Food availability seems to interfere in the reproduction period of this species such as in marsupials of the Caluromys genus. In addition, these new records corroborate results presented by other recent findings, indicating that the geographic distribution of this species in Brazil is more extensive than thought before and can include disturbed areas in the Amazon forest.
