It is hard to guess what a Hylaeamys oniscus weights. But we have the answer:
An adult Hylaeamys oniscus (Oryzomys oniscus) on average weights 49 grams (0.11 lbs).
The Hylaeamys oniscus is from the family Muridae (genus: Oryzomys). When reaching adult age, they grow up to 11.2 cm (0′ 5″).

Hylaeamys oniscus, the sowbug rice rat, is a rodent species in the genus Hylaeamys of family Cricetidae. It was formerly placed in the genus Oryzomys as Oryzomys oniscus.It occurs only in northeastern Brazil.
