Systematics

The Davao squirrel is classified as an independent species within the genus of the Sunda tree squirrel ( Sundasciurus ), which - depending on the author - consists of 15 to 17 species. The first scientific description comes from Colin Campbell Sanborn from 1952, who described the species using an individual from Madaum in Tagum City in the Davao del Norte province on the Philippine island of Mindanao .

Apart from the nominate form, no subspecies are distinguished within the species .

Status, threat and protection

The Davao croissant is not classified by the International Union for Conservation of Nature and Natural Resources (IUCN) in a hazard category, but is classified as "data deficient" due to the lack of data on population, distribution and lifestyle. It is believed that the species can be considered safe with a focused search.
