Rupicolous Dipodil

discussion

Discussion: Subgenus Petteromys. A distinctive species (2 n = 52, FNa = 72) that is morphologically adapted to climb about on rocky outcrops and may be restricted to such habitats, which is unusual among species of Dipodillus and Gerbillus. Granjon et al. (2002 a) described the species, compared it with others, and provided observations on habitat and behavior. The Rupicolous Dipodil is one of nine species of Gerbillus and Dipodillus occurring in a small area of the West African sahelian region located between SE Mauritania, N Mali, and W Niger. Dipodillus rupicola was found in close proximity to G. tarabuli, G. nigeriae, and G. henleyi, but only D. rupicola was caught on the rocks along with a species of Acomys, another rupicolous muroid. Granjon et al. (2002 a) described rupicola as a Gerbillus but in the classification of Pavlinov et al. (1990), which we follow here, it would be placed in subgenus Petteromys of Dipodillus; in morphology and body size, D. rupicola is most like D. campestris, but differs strikingly in karyotype.
