The Niobe black chipmunk ( Lariscus niobe ) is a type of squirrel from the genus of the black chipmunk ( Lariscus ). It occurs in Indonesia on the islands of Java and Sumatra .
features
The Niobe black chipmunk reaches a head-torso length of about 18.9 to 19.5 centimeters. The tail becomes 8.5 to 9 centimeters long and is thus significantly shorter than the rest of the body. It is the darkest species of the genus with a dark brown fur on the back, on which the black stripes are barely visible. The ventral side is a little lighter. The tail is short with an indistinct black or black mottled stripe on the underside.
distribution
The Niobe black chipmunk is found in Indonesia in the high altitudes of the islands of Java and Sumatra . The occurrence on Sumatra is limited to the mountain forests on the west coast and on Java on the Ijen in the east of the island.
Way of life
No information is available about the lifestyle of the Niobe black chipmunk. It occurs in primary forests as well as in secondary stands and bushes and lives primarily on the ground.
Systematics
The Niobe black chipmunk is classified as a separate species within the genus of the black chipmunk ( Lariscus ), which consists of four species. The first scientific description comes from Oldfield Thomas from 1898, who described the species on the basis of individuals from the area of Pajokombo in the highlands near Padang .
Within the species, together with the nominate form, two subspecies are distinguished:
- Lariscus n. Niobe : nominate form, occurs in the west of the island of Sumatra.
- Lariscus n. Vulcanus : The subspecies occurs in the area of the Ijen volcanic complex on Java. The hair of the tail has white or light sand colored tips.
Status, threat and protection
The Niobe black chipmunk is classified by the International Union for Conservation of Nature and Natural Resources (IUCN) as “data deficient” due to a lack of data on distribution and population size.
