The Kintampo redshank squirrel ( Funisciurus substriatus ) is a species of squirrel from the genus of the redshank squirrel ( Funisciurus ). It occurs in parts of West Africa .
features
The Kintampo redshank squirrel reaches an average total length of about 30.0 to 34.8 centimeters, with 13.0 to 17.8 centimeters being the length of the tail . The weight is about 115 to 190 grams. The rear foot length is 40 to 45 millimeters, the ear length 13 to 19 millimeters. It is a medium-sized squirrel with a greenish-yellow to ocher-colored and black-speckled back fur. There is an indistinct, light side stripe on each side, which is delimited by a black line on the belly side. The peritoneum is white with pale ocher washings, the individual hairs are dark gray at the base. The colors of the legs correspond to the fur on the back. The tail is as long as the head-trunk length. It is darker than the back color and has clear black and sand-colored rings. The females have two paired teats (0 + 0 + 1 + 1 = 4).

The skull has a total length of 42.5 to 45.3 millimeters and a width of 26.2 to 28.2 millimeters. Like all species of the genus has the type in the upper jaw half per one to a incisor tooth formed incisor (incisor) to which a tooth gap ( diastema follows). This is followed by two premolars and three molars . The teeth in the lower jaw correspond to those in the upper jaw, but only with a premolar. In total, the animals have a set of 22 teeth. The bony palate ends at the anterior margin of the last molars.
The Kintampo redshank squirrel is similar to the Thomas redshank squirrel ( Funisciurus anerythrus ) in that it is very similar in habit and color. The distribution areas do not overlap and the Thomas redshank squirrel has no ocher to orange wash of the peritoneum in the populations in the south and east of Cameroon.
distribution
The Kintampo redshank squirrel is found in parts of West Africa . The distribution area includes parts of Burkina Faso , Togo , Benin and the east of Ghana north of the forest regions and east of the Volta . The IUCN also specifies southern Niger as part of the distribution area. It is unclear whether it occurs in Nigeria .
Way of life
Very little information is available about the way of life of the Kintampo redshank squirrel. It lives in the West African forest savannah and in drier gallery forests. It lives solitary or, less often, in pairs. The species lives mainly on the ground and in bushes and trees, like other squirrels it feeds primarily on herbivores . When there is potential danger or excitement, the species lowers its tail. A maximum lifespan of 6.9 years is documented in captivity.
Systematics
The Kintampo redshank squirrel is classified as an independent species within the genus of the redshank squirrel ( Funisciurus ), which consists of ten species. The first scientific description comes from the zoologist William Edward de Winton from 1899, who described the animals using individuals from the area around Kintampo in Ghana (then named as the hinterland of the British colony Gold Coast ). The species status has been confirmed, but it is not really clear whether it is genetically isolated from the Thomas redshank squirrel ( Funisciurus anerythrus ) in western Uganda .
Apart from the nominate form, no further subspecies are distinguished within the species .
Status, threat and protection
The Kintampo redshank squirrel is not classified in a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to the limited amount of data available and the uncertainties about occurrence, lifestyle and potential threats, but rather listed as "data deficient".
