The subfamily Heteromyinae (spiny pocket mice) represents a well-defined monophyletic group within the
rodent family Heteromyidae. Although 2 genera of spiny pocket mice, Heteromys and Liomys, are recognized in
the subfamily, no phylogenetic analysis has demonstrated their reciprocal monophyly. A recent study using
DNA-sequence data from the mitochondrial gene cytochrome b suggested that Liomys is paraphyletic but
included few species of Heteromys. Here, we conduct phylogenetic analyses of the subfamily with dense
taxonomic sampling using allozymic data from a previous study and external and cranial morphological data; our
aim is to assess generic monophyly and elucidate phylogenetic structure within the genera, to the degree possible
