Overview

Distribution

Range Description

The exact range of this mongoose is uncertain, but it occurs in north-eastern DR Congo, Central African Republic, extreme southern Sudan and Uganda (Stuart and Stuart in press). It may occur further west than current records indicate. Old specimens in the Paris Natural History Museum were collected at Sanghe, but it is not clear whether this is the district in the Congo Republic, or that in the Central African Republic (Schreiber et al. 1989).

Physical Description

Morphology

Physical Description

Dologale dybowskii is a relatively small mongoose with brown fur covering its body and limbs. Its tail is bushy and is also brown. Both its underparts and face are gray with the latter being darker. Its claws on its forefeet are robust and powerful (Kingdon, 1997).

The head to body length of this African mongoose ranges from 25 to 33 cm while the tail length ranges from 16 to 23 cm. The hind leg is approximately 5.5 cm and its weight ranges from 300 to 400 grams (Kingdon, 1979).

Dologale dybowskii is sometimes confused with the dwarf mongoose Helogale due to their similar size and appearance. However, Helogale has a groove in its upper lip that Dologale dybowskii lacks (Kingdon, 1979). Furthermore, Dologale dybowskii has a shorter palate and weaker teeth than Helogale (Kingdon, 1997).

Range mass: 300 to 400 g.

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Apparently confined to a narrow belt of savanna-forest mosaic north of the Equator. It is known to occupy the thicketed shores of Lake Albert, as well as montane forest grasslands (Stuart and Stuart in press). Kingdon (1977) suggested that this is a mongoose living in the ecotone between high forest and lower rainfall wooded savanna. Insectivorous.

Dologale dybowskii has a wide range of habitats ranging from the shores of Lake Albert to the forest grasslands of the Imatong Mountains. It has also been spotted in the savanna forests of Mubende and is therefore, often referred to as the African Savanna Mongoose (Kingdon, 1979).

Trophic Strategy

Food Habits

The food habits of Dologale dybowskii are not certain. However, the large digging claws, as well as the lack of specialization of the teeth, suggests that it may eat fossorial invertebrates, including termites, and small vertebrates (Kingdon, 1997).

Animal Foods: insects

Primary Diet: carnivore (Eats terrestrial vertebrates, Insectivore )

Associations

Ecosystem Roles

There has been no direct evidence linking Dologale dybowskii to any ecosystem roles. However, due to its habitat and hypothesized food behavior, one may assume that Dologale dybowskii affects plant, vertebrate, and invertebrate populations.

Justification
Listed as Data Deficient as this species is known only from museum specimens and a handful of sightings, its distribution range is unclear, and there is no information on current population status or major threats. Given that its habitat is sufficient stable in its known range, it is possible that with further study this species will be shown to be appropriately listed as Least Concern.

Conservation Actions

Conservation Actions
The only protected area from which this species has been recorded is the Garamba N.P. in north-eastern DR Congo. Lack of knowledge of this species’ biology and habitat requirements make this a priority species for study (Stuart and Stuart in press).
