Identification.

Small-sized. The upperparts are grey-brown to dark grey, while the underside, legs and feet are totally white or cream coloured. The tail length is typically equal to the head and body length, making this spiny pocket mouse unique compared to the three congeneric species found in Costa Rica, whose distributions do not overlap with its range ( Reid and Gόmez Zamora 2022). Occasionally recorded in the study area in moist and transitional forests.
