A New Montane Species of Spiny Pocket Mouse ( Rodentia : Heteromyidae : Heteromys ) from Northwestern Costa Rica

  title={A New Montane Species of Spiny Pocket Mouse ( Rodentia : Heteromyidae : Heteromys ) from Northwestern Costa Rica},
  author={Robert P. Anderson and Robert Timm},
Recent taxonomic works have recognized only two species of spiny pocket mice of the genus Heteromys (Rodentia: Heteromyidae) from Costa Rica. Within Costa Rica, the widespread H. desmarestianus is considered to occur throughout the wet Caribbean lowlands, as well as at middle and high elevations on the Caribbean and Pacific slopes of the country’s main montane systems. In contrast, H. oresterus is known from only a few localities at high elevations in the western portion of the Cordillera de… CONTINUE READING
