Although the origin and center of diversity of the rodent family Heteromyidae (spiny
pocket mice and relatives) lie in North or Central America (ROGERS1990),two species of
Heteromys are known to inhabit northwestern South America Heteromys anomalus
(Thompson, 1815) is distributed across northern Venezuela and Colombia and in the Rio
Magdalena Valley of central Colombia. Heteromys australis Thomas, 1901 is known only
from northwestern Ecuador north through western Colombia to eastern Panama and east
