Species of mammals belonging to the spiny rat family of rodents
The Boyacá spiny rat (Proechimys chrysaeolus ) is a species of
rodent in the family
Echimyidae .
[2] It is
endemic to
Colombia ; it is found primary forest in
Carare River valley,
Boyacá Department , 100 to 500 meters above sea level. Nocturnal, terrestrial and solitary, it feeds on seeds, fruit and some leaves and insects. It is threatened by
habitat loss for mining and agriculture.
Phylogeny
Morphological characters and mitochondrial cytochrome b DNA sequences showed that P. chrysaeolus belongs to the so-called trinitatus group of Proechimys species, and shares closer phylogenetic affinities with the other members of this clade:
P. trinitatus ,
P. mincae ,
P. guairae ,
P. poliopus ,
P. magdalenae ,
P. urichi , and
P. hoplomyoides .

The cladogram has been reconstructed from morphological characters and mitochondrial DNA (
cytochrome b ) sequences.
