Overview

Distribution

Range Description

The exact range of this mongoose is uncertain, but it occurs in northeastern Democratic Republic of the Congo (DRC), Central African Republic (CAR), extreme southern South Sudan and Uganda (Aebischer et al. 2013, Stuart and Stuart 2013, Woolgar 2014). It may occur further west than current records indicate. Old specimens in theMusum National d'Histoire Naturelle, Paris,were collected at 'Sanghe', but it is not clear whether this is the district in the Congo Republic, or that in CAR (Schreiber et al. 1989).

Physical Description

Morphology

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.

Other Physical Features: endothermic ; bilateral symmetry

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
It is apparently confined to a narrow belt of savannaforest 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 2013). Kingdon (1977) suggested that this is a mongoose living in the ecotone between high forest and lower rainfall wooded savanna. In the Chinko/Mbari drainage basin (CAR), Aebischer et al.(2013) observed individuals in a mosaic of tropical wet savanna and deciduous tropical lowland forest, and more precisely in an area that was dominated by savanna woodland. This species is probably essentially diurnal and lives inpossiblyloosegroups (Aebischer et al. 2013, Woolgar2014), as observed in all otherspecies ofMungotinae (Veron et al. 2004, in press). Thisspeciesperhapsusestermite mounds as nocturnal shelters (Aebischer et al. 2013). Woolgar (2014) observed a group of eight individuals foraging and reported that they generally pounced on insects on the ground, but at various times they all dug in the loose soil and also turned over light stones along the path. Although they largely fed alone, they remained in contact with a series of vocalisations reminiscent of other communal mongoose species.

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

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).

Associations

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
This species is listed as Data Deficient because this species is known only from museum specimens and a handful of sightings, its distribution range and (micro-)habitat preferences are unclear, and there is no information on current population status or major threats. Up until very recently, it was entirely plausible that the species could qualify as being at high risk of extinction, but it could also be going undetected and actually be more common than thought. Recent records from Central African Republic and Uganda lend some credence to the latter theory, suggesting that past confusion by observers with Common Dwarf Mongoose (Helogale parvula) may be responsible for the apparent paucity of records. Ongoing studies will undoubtedly confirm whether this is the case or not, but in the interim the species is tentatively retained as Data Deficient. Given that habitats encompassed in Pousargues's Mongoose known range are relatively stable, if further research indeed confirms that the species is not as rare as has been stated, then it islikely that it will warrant listing as Least Concern.

Population

Population
This species is known from just 31 museum specimens and a handful of sightings. Until recent records photographically documented by Aebischer et al. (2013) in CAR and Woolgar (2014) in Uganda, there had been no known positive records for more than two decades (Stuart and Stuart 2013).

Threats

Major Threats
Current potential threats to this species are unknown, but the fast and enormous increase of transhumance in eastern CAR, northern DRC and western South Sudan might have a negative impact on the population of Pousargues's Mongoose in the future.

Conservation Actions

Conservation Actions
The only protected areas from which this species has been recorded are the Garamba N. P. in northeastern Democratic Republic of the Congo, the Chinko Project Area in Central African Republic, and Semliki Wildlife Reserve (not to be confused with Semliki N. P.) in Uganda (Woolgar 2014). Lack of knowledge of this species biology and habitat requirements make this a priority species for study (Stuart and Stuart 2013).
