Description
Mylomys dybowskii (Pousargues, 1893)
Golunda dybowskii Pousargues, 1893: 163.
Mylomys dybowskii – Thomas 1906: 224.
REMARKS
The MNHN-ZM-MO-1998-1013 specimen was karyotyped and its chromosome formula is 2N =42, NF =52 (Gautun et al. 1986) like other representatives of Côte d’Ivoire (Matthey 1970). Morphologically this specimen agrees well with the type specimen but it corresponds to a juvenile individual (Table 7). The pelage is dorsally bicolored (speckled) with a brown general dominant coloration and the bicolored tail is dark above and light below. Contrary to Arvicanthis Lesson, 1842 it has three digits on the hindfoot and four on the forefoot, as well as a white belly. The juvenile Nimba specimen was in alcohol and is poorly preserved. The skull is robust, the rostrum wide with a sharp occipital, there is a long and wide infraorbital foramen. The molars are large and characterised by a selenedont pattern of the cusps (UTR: 8 mm; Upper M1/ Width: 1,7mm). The cusps are high and are not fused in laminae. This is also visible on much worn molars of other specimens of the species. The central cusps are high and prominent (t2, t5 et t8) in the upper molars.
