摘要：
A new species of Chrotomys (C. gonzalesi) is described from Mount Isarog on the Camarines Peninsula of southeastern Luzon Island, Philippines. It is one of four species of murid rodents confined to high elevation forest on this mountain. The new species is distinguishable from congeners by its relatively lower braincase, broader mastoid region, broader palate, and darker pelage. Data suggest that the new species is semifossorial, active both day and night, and feeds on annelid worms and soft-bodied arthropods. This discovery supports a general pattern of vicariant speciation between the high-lands of northern and southern Luzon.
