Chrotomys gonzalesi Rickart and Heaney 1991, Proc. Biol. Soc. Wash., 104: 389.

Type Locality: Philippines, SE Luzon Isl, Camarines Sur Province, W slope Mt Isarog, 4 km N, 21 km E Naga, 1350 m.

Vernacular Names: Isarog Chrotomys.

Distribution: Greater Luzon Faunal Region in the Philippine. Known only from Mt Isarog, Luzon, in lower and upper montane evergreen forest formations, 1350-1750 m (Heaney et al., 1998, 1999).

Conservation: IUCN – Critically Endangered.

Discussion: Morphology, ecology, and comparisons with other species of Chrotomys provided by Rickart and Heaney (1991) and Rickart et al. (1991). Altitudinal distribution and ecology summarized by Heaney et al. (1999). Standard karyotype (2n = 44, FN = 52; Rickart and Musser, 1993) indistinguishable from those of Rhynchomys isarogensis and Chrotomys silaceus (Rickart and Heaney, 2002; the latter recorded as Celaenomys).
