The arrow indicates the supernumerary or B chromosom. yellow dorsal pelage and displays a white stripe on the flanks which identifies it as  P. flavovittisPeters, 1852rather than  P.cepapiSmith, 1836or  P.ochraceusHuet, 1880, which also live in the region. It is also different from the red-bellied coast squirrel  P.palliatusPeters, 1852, that is found in the coastal forests of Kenya, Tanzaniaand Mozambique. Kingdon (1974)described intermediate forms between  Paraxerus cepapi, a typical squirrel of the southern savannas and miombo woodlands occurring between the Rufiji river and east of lake Malawi, and  P. palliatus, which he interpreted as a hybridization zone between the two species. Similarly,he indicates that  Paraxerus flavovittisis common in all habitats between Rufiji and Rovuma rivers, but very rare in the north of Tanzaniaand is not known in the south of Mozambique.  TABLE 18. — Standard karyotype data for east and south African  GerbilliscusThomas, 1897species from the literature and this work.

To our knowledge, it is the first description of karyotype in the genus  Paraxerus.
