This species is endemic to the Philippines. Originally described from Dinagat island to the north of Mindanao, the species has also been reported from the nearby islands of Bucas Grande and Siargao. This species lives in old growth lowland rainforest, second-growth forest, and "bonsai" forest (a low productivity area with stunted trees which are not economically valuable). On all three islands, it appears to be moderately tolerant of habitat disturbance. On the Bucas Grande, the species occurs in disturbed forest on limestone, and in patchy areas of forest adjacent to agricultural areas. It persists in reasonable numbers in fairly heavily degraded areas for example at edges of farms, but it does not occur where good forest is not nearby, or in areas completely dominated by humans. Classified as Endangered (EN B2ab(ii,iii)) on the IUCN Red List of Threatened Species.

The species original distribution has been and continues to be reduced by logging and firewood collection. Habitat loss due to mining of nickel and chromite in the remaining old-growth area is a threat in addition to quarrying of limestone for road building. The forest area of Dinagat is less than 50 km2 and the entire island is a mining concession.

There are no conservation measures in place. Field surveys need to be carried out to determine the status of this species. Research on the habitat requirements and threats facing the species are necessary to plan future conservation actions. Effective protected areas need to be established.

Very little is known about the ecology of this species. The Dinagat moonrat has stiff bristly or spiny fur on its back, which is generally golden brown with black speckling. The underparts lack spines and are mostly brownish-grey. The ears are relatively large and sparsely covered with short white or dark brown hairs.
