| 摘 要： | 社鼠、雷琼社鼠和针毛鼠都是山地栖息种类，它们染色体的2n数目和形态明显有别于同属的其他各种．体现出它们之间的亲缘关系较近，它们间的核型演化是通过罗伯逊易位和缺失途径，社鼠、雷琼社鼠和针毛鼠有着不同于属中其他种类的生态位，把它们另作一属会恰当些；社鼠和雷琼社鼠的地理分布有所不同．但染色体组型并不差异．认为它们间可能仅是毛色变异，而不存在两个亚种之分．

| Abstract: | haus confucianus, R. confucianus lotipes and R. fulvescens and the kinds living in mountains. Their chtomosomes in 2n number and shape diffet obviously from the other species in the same genus. It embodies that their kinship is claser. Robeson' translocation and deficiency bring about the evolution of the karyotypes between them. The ecological nichcs of R.confucianus, R. confuciannus lotipes and R fulvescent siffer from the other species in the same genus.They should be Considered as an other genus. Perhaps it is more appropriate R. confucianus differs from R. confucianus lotipes in geographical distribution, but their karyotypes aren' t different.They shouldn' t divide into two subspecies. |
