"G. gallarum" is sympatric with "G. senegalensis" but is differentiated in the measurements of hind limb, hind foot, ear and tail-length. In the field, the general appearance, call and preferred habitat aid in discriminating between them. The Kenyan coast galago "Gallagoides cocos" is another species the range of which overlaps the southern margin of the Somali galago's range in Kenya and Somalia. Both these galagoes have calls distinct from that of the Somali galago and occupy moister habitats. The ears of these galagoes appear Grey and brown respectively with a pink patch visible in front of the lower ear.
