Three karyotypically differentiated species of harsh-furred mice, Lophuromys melanonyx (2n = 60, NFa = 90; 24m,sm + 8st + 26a + Xm + Ya), Lophuromys sp. A (2n = 54, NFa = 60; 8m,sm + 44a + Xa + Ya), and Lophuromys sp. B (2n = 68, NFa = 78; 8m,sm + 4st + 54a + Xst + Ya), were found at the Bale Mountains National Park, Ethiopia. Comparative analysis of chromosomes showed that G-banding patterns of 2 to 17 chromosome banding patterns or chromosome arms were identical in all species. Apparently, the formation of the studied species was associated with their independent karyotypic divergence during early evolution. The results obtained indicate that the rate of karyotypic alterations is not associated with the degree of morphological differentiation in this group of species.
在埃塞俄比亚的巴勒山国家公园发现了三种核型不同的硬毛鼠，即黑爪硬毛鼠（2n = 60，NFa = 90；24m,sm + 8st + 26a + Xm + Ya）、硬毛鼠A种（2n = 54，NFa = 60；8m,sm + 44a + Xa + Ya）和硬毛鼠B种（2n = 68，NFa = 78；8m,sm + 4st + 54a + Xst + Ya）。染色体的比较分析表明，所有物种中2至17号染色体带型或染色体臂的G带模式是相同的。显然，所研究物种的形成与其在早期进化过程中独立的核型分歧有关。所得结果表明，这一组物种的核型改变速率与形态分化程度无关。
