[Elektronische Daten] [V. Volobouev, J. Gautun, B. Sicard, M. Tranier] We present here data on chromosome banding analysis (R- and C-bands) ofAcomys sp. (Rodentia, Muridae) from Oursi, Burkina Faso, characterized by 2n=FN=68 and comparison of its banding patterns with those ofAcomys dimidiatus from Saudi Arabia (2n=38, FN=70), studied previously. The study revealed complete homology between acrocentric chromosomes ofAcomys sp. and chromosome arms of 16 pairs of metacentric and two pairs of acrocentric chromosomes ofA. dimidiatus. In addition to monobrachial homology, one tandem translocation accompanied by a centromeric shift was identified in the karyotype of the latter species. The data obtained show that karyotypes of all the species of theAcomys cahirinus-dimidiatus group studied previously may be derived from that ofAcomys sp. from Oursi by means of numerous non-homologous Rb translocations and 1-2 tandem translocations, and thus its karyotype may be considered as ancestral for thecahirinus-dimidiatus group.
