Description of the karyotype of Heimyscus fumosus and of several other murids from the Mount Doudou area (Gabon)

A first inventory of south-western Gabon forest rodent diversity was realised in the Mount Doudou AERF using cytotaxonomic analysis. The C-banded karyotypes of some Heimyscus, Hylomyscus, Praomys, Hybomys and Malacomys species are presented. Two karyotypes are here described for the first time : those of Heimyscus fumosus and Hylomyscus sp. The results of this chromosomal analysis increase the murine specific diversity recognized in central Africa : there probably exists a new species of Hylomyscus in the Mount Doudou area.
