FIGURE 1. Chronological frame of the Nesiotites species described in the Balearic Islands. The Quaternary chronology follows Gibbard et al. (2010). MN zones according to Agustí et al. (2001). (*): The taxonomical identity of N. meloussae and the presence of a separate phylogenetic lineage of the genus in Menorca are controversial and are currently under discussion.

FIGURE 2. Location map (left) and topographic survey (right) of the palaeontological deposit from Caló den Rafelino. Arrows and grey colored zone indicate the exact location of the fossiliferous breccia.

FIGURE 3. Nesiotites rafelinensis sp. nov. Holotype IMEDEA 91950, incomplete left mandible from the earliest Early Pliocene site of Caló den Rafelino, in (1) buccal, (2) occlusal, and (3) lingual views.

FIGURE 4. Bivariate diagram of the m1's L and TAW measurements. Measurements of Asoriculus gibberodon taken from Fejfar and Horácek (1983), Marchetti et al. (2000), and Rofes and Cuenca-Bescós (2006). Measurements of Asoriculus thenii taken from Malez and Rabeder (1984). Nesiotites ponsi specimens are from the site of Cruis de Cap Farrutx, Mallorca (Late Pliocene); Nesiotites aff. ponsi specimens from Pedrera de s'Onix, Mallorca (Early Pleistocene); Nesiotites hidalgo specimens from Cova de Llenaire, Cova de Canet, and Cova Estreta, Mallorca (Late Pleistocene/Holocene); N. meloussae specimen from Barranc de Binigaus, Menorca (Early Pleistocene); Asoriculus similis specimens from Sardinia (Late Pleistocene); Asoriculus gibberodon specimens from Vceláre 3, Slovakia (Late Pliocene), Monte La Mesa, Italy (Early Pleistocene), and Sima del Elefante, Spain (Early Pleistocene); Asoriculus thenii specimens from Podumci 1 and Tatinja Draga, Croatia (Early Pleistocene). Convex hulls, distribution; Ellipses, 95% confidence.

FIGURE 5. Principal component analysis (PCA) showing plot of components 1 against 2. Measurements of the lower teeth and the mandible used: Lm1, TAWm1, Hm2, and Lm1-m3. Measurements of Asoriculus gibberodon and A. thenii taken from the same sources as in Figure 4. Specimens other than that of Caló den Rafelino are from the same locations as in Figure 4. Details can be found in Table 2. Convex hulls, distribution; Ellipses, 95% confidence.
