Physical Characteristics
- Head and body length:
46-56 cm

The white-spotted chevrotain is intermediate in size between the Indian chevrotain (Moschiola indica), which it resembles closely, and the smaller yellow-striped chevrotain (Moschiola kathygre). The hind legs are relatively long, and the back is characteristically hunched. The overall color is a dull brown, punctuated with a broken pattern of white spots on the sides and back. These spots are generally arranged into four or five rows along the sides, and, unlike the yellow-striped chevrotain, the spots tend to be discrete and only rarely merge to form stripes. Three white bands cross the rump. The undersides are pale beige, and this coloration merges gradually with the upperparts. Down the centre of the belly is a pale cream-colored stripe which continues up the throat to the underside of the chin. Two pairs of white stripes flare off of this central stripe: by the angle of the jaw and partway down the throat. The forehead and top of the head are dark brown. Antlers are not present, but males have long upper canine teeth which are visible as small tusks.
- Similar species
- The dull gray-brown body and white spot pattern differentiate the white-spotted chevrotain from the yellow-striped chevrotain (Moschiola kathygre), also found on the island of Sri Lanka.
- The Indian chevrotain (Moschiola indica) is visually similar, but is larger and found on the mainland, rather than Sri Lanka.
- The water chevrotain (Hyemoschus aquaticus) is superficially similar, with a stripe-and-spot pattern on a reddish-brown coat; the water chevrotain is larger and easily distinguished by its African distribution.
Reproduction and Development
No information on the reproductive biology of the white-spotted chevrotain has been published. Likely similar to the Indian chevrotain (Moschiola indica).
Ecology and Behavior
- Family group:
Solitary.
- Diet: Unreported, but likely leaves and fruit like the other Moschiola species.
- Main Predators: Unreported, but likely medium- and large-sized carnivores as with the yellow-striped chevrotain (Moschiola kathygre).
- Diet: Unreported, but likely leaves and fruit like the other Moschiola species.
Habitat and Distribution
Conservation Status
- IUCN Red List:
Least Concern (2015).
- CITES Listing: Not listed (2019).
- Threats: Habitat loss, hunting.
- CITES Listing: Not listed (2019).
No formal assessments for the white-spotted chevrotain have been performed, in part due to the uncertainty of its taxonomic status. It is commonly hunted, and there has been significant forest destruction in its range over the past few centuries. However, this species occurs in several protected areas and appears to be at least somewhat resistant to habitat modification.
