Abstract: Bats were captured by using nets and hand picking and then chromosome preparations were made from bone marrow cells according to Lee and Elder’s (1980) method cited in Hillis et al. (1996) with some modifications. Somatic metaphase chromosomes of bat specimens collected from Arbaminch, Koka, Merehabete and Ziway regions in Ethiopia were studied. The specimens were identified belong to the following families and species. Pipistrellus pipistrellus and Scotophilus dinganii or S. viridis (family Vespertilionidae), Micropteropus pusillus (family Pteropidae), Chaerephone pumila (family Molossidae) and a taxonomically yet unidentified specimen collected from Merehabete region. Five karyotypes, differing in chromosome number, fundamental number and chromosome morphology were identified. Accordingly, the karyotype of Micropteropus pusillus consists of 2n=35, FN=70 and in rare cases 2n=36, FN =72 with all the chromosomes being biarmed; Pipistrellus pipistrellus 2n=36, FN=52 with metacentric and acrocentric chromosomes; Scotophilus dinganii(S.viridis) 2n=36, FN=54 with metacentric/ acrocentric chromosomes; Chaerephon pumila 2n=48, FN=60 with metacentric, acrocentric and telocentric chromosomes;Merehabete specimen 2n=42,FN=82 with 40 biarmed and two telocentric chromosomes. The present karyotypes differed from previous reports either in 2n number, or fundamental numbers or chromosome morphology.
