Abstract
Tweedy’s Crab-eating Rat, Ichthyomys tweedii Anthony, 1921, was described based on just a few specimens, and many aspects of its biology remains unclear. The species has only been previously reported to occur in two geographically disjunct areas in Panama and Ecuador. We report a new record of this species for southern Costa Rica. Our new record is the first for this species and the genus for Costa Rica, as well as the northernmost expression of the genus.
