The bushbaby (genus: Galago), a tarsier-mimic

Figure 1. Galago skeleton. Note the elongate tarsals and large orbits, both convergent with Tarsius.

The Senegal bushbaby,
Galago senegalensis (Figs. 1, 2) is a small primate in the Lemur lineage, most closely related to Perodicticus potto (Fig. 3) in the large reptile tree (LRT, 1373 taxa), despite sharing a long tail, elongate tarsals and large orbits with the tarsier, Tarsius (Fig. 5). These relationships follow traditional cladograms.

Galago senegalensis (É. Geoffroy, 1796) is the Senegal bushbaby, a small nocturnal lemur close to Lemur catta and the potto, Perodicticus. Convergent to Tarsius, the proximal tarsals are elongated. The anterior upper incisors are missing. The medial incisors are appressed to the canines.\

Figure 4. Perodicticus potto, the extant potto, has a typical lemur dentition, lacking giant incisors.

Some skulls attributed to Galago
have 4 molars rather than the 3 shown here (Fig. 2).

Figure 2. Tarsius, the extant tarsier. Note the several autapomorphies displayed here vs. the many plesiamorphies in Darwinius.

Figure 5 Tarsius, the extant tarsier. Note the elongate calcaneum and astragalus, as in Galago.
