Recognised as a species distinct from G. senegalensis by Nash et al. (1989) and Groves (1989).

Lower Risk, near threatened (LR: nt).

Very little is known on the ecology of this species, and no specific studies have been carried out. A quite detailed description of its habitat is reported in Nash et al. (1989). The species’ occurrence in Ethiopia and Eritrea is analysed in Yalden et al. (1996). General information on the species’ ecology and distribution is found in Kingdon (1997), and Stuart & Stuart (1997). Status and threats are discussed in Oates (1996).

Known extent of occurrence

G. gallarum is known within the area delimited by the Webe Shebele and Tana river valleys to the northeast and southwest respectively, bounded by the Ethiopian Rift Valley to the north west (Nash et al., 1989). The distribution map (Fig. 2.2.4.a) was acquired from Nash et al. (1989) and revised on the basis of the information found in this source, and in Oates (1996) and Kingdon (1997). The final range was also tested with the river network.

This species is the most xerically adapted of the galagos and lives primarily in bushlands and thickets (Kingdon, 1997; Nash et al., 1989).

Based on these environmental preferences, the following scores were assigned (Fig. 2.2.4.b) (Tab. 2.2.4.a):

The output of the probabilistic-continuous (PC) distribution model is shown in Fig. 2.2.4.c.

No occurrence of the species within the four sample areas.

The known EO of this species is classified as 50% suitable and 28% moderately suitable. The less suitable areas are found in Ethiopia and northern Kenya. Fragmentation is limited, especially when the moderately suitable areas are included in the AO. The AO is thus one large suitable patch and the AWMSI also indicates a rather compact shape. The species is classified as Lower Risk, and human pressure on bushlands and woodlands are the major threats. About 10% of the total AO is included in existing protected areas.
