| karyotypic differences in two sibling species of scotophilus from south africa (vespertilionidae, chiroptera, mammalia). | karyotype descriptions are given for scotophilus dinganii (2n = 36, fna = 50) and a recently discovered sister-species, scotophilus sp. nov. (2n = 36, fna = 52). these two sibling species occur sympatrically and are distinguished by body size, echolocation frequency and cytochrome b sequence. cytogenetically, both species differ from other scotophilus species in the subtelocentric morphology of chromosome 2 and a terminal heterochromatic segment on the x chromosome. further, scotophilus sp. nov. ... | 2007 | 17901703 |
