The Hainan rat hedgehog ( Neohylomys hainanensis ) is a species of hedgehog from the subfamily of the rat hedgehog (Galericinae), which is endemic to the Chinese island of Hainan .
features
The Hainan rat hedgehog reaches a head-trunk length of 13.2 to 14.7 centimeters and a tail length of 3.6 to 4.3 centimeters. Its weight is around 50 to 70 grams. The hind feet are 21 to 36 millimeters long. Compared to the small rat hedgehog , the Hainan rat hedgehog has a relatively long tail, which makes up about 30% of the length of the head and torso and is longer than the hind feet. Its fur is colored red-brown on the upper side and has a black stripe on the back, the underside is lighter, usually light gray or yellowish. As with the small rat hedgehogs, the snout is flexible and elongated and serves to search for food in the ground.
distribution
The distribution area of the Hainan rat hedgehog is limited to the Chinese island of Hainan .
Way of life
Little is known about the way of life of the Hainan rat hedgehog. Their habitat are tropical and subtropical rainforests, where they are mostly on the ground. They use underground structures as sleeping places. As with the small rat hedgehogs, the food is likely to consist primarily of insects and worms.
Systematics
The Hainan rat hedgehog is assigned as an independent species and genus to the rat hedgehogs (Galericinae) within the hedgehogs (Erinaceidae). Hainan rat hedgehogs are closely related to the small rat hedgehogs ( Hylomys ), to which they have been assigned by individual authors, but differ in their longer tail, the number of teeth and the somewhat larger dimensions.
Hazard and protection
The species is on the International Union for Conservation of Nature and Natural Resources (IUCN) due to the very small distribution area, which is restricted to the island of Hainan, and the destruction of their habitat by deforestation of the humid forests as threatened and the expansion of agricultural land ( endangered ) listed.
The populations of this species are estimated to be very small, but current data on population size are not available.
