The basic diploid and fundamental autosomal arm numbers were 44 and 87, respectively. Moreover, chromosomal variation was observed which might be due to the existence of B-chromosomes. The karyotype formula was 2n=♂44~48, NF=87~95, 18(m)+24(sm)+0~4 B m (m or sm), XY (st, t). The results suggested that Mesechinus miodon should be defined as a valid species rather than a synonym of M. dauuricus. 2016,(35): 217-220 收稿日期:2015-10-09 DOI:10.11984/j.issn.1000-7083.20150309 分类号:Q959.8 基金项目:陕西省科学院科技计划项目(2014K-16) 作者简介:孔飞, 助理研究员, 研究方向:动物生态学, E-mail:k.coffee@163.com 参考文献: 陈广文, 董自梅, 田士瑞, 等. 2010. 河北3 产地日本三角涡虫的染色体变异与核型多样性分析[J]. 动物学杂志, 45(6): 85-91. 陈宜峰, 郭健民. 1986. 哺乳动物染色体[M]. 北京: 科学出版社: 8. 林炜, 闵芝兰. 1989. 两种短棘猬染色体组型分析[J]. 西北大学学报, 19(1): 69-72. 闵芝兰, 林炜. 1989. 陕西省猬科(Erinaceidae)分类的研究[J]. 西北大学学报, 19(4): 71-79. 束峰珏, 张锡然, 曹祥荣, 等. 1999. 毛冠鹿B染色体多态及遗传机制探讨[J]. 遗传, 21(6): 23-26. 汪松, 解焱, 王家俊. 2001. 世界哺乳动物名典[M]. 长沙: 湖南教育出版社: 17-18. 王应祥. 2003. 中国哺乳动物种和亚种分类名录与分布大全[M]. 北京: 中国林业出版社: 2-4. 杨凤堂, 马彩霞, 施立明. 1991. 远东刺猬和大耳猬的核型分析[J]. 动物学研究, 12(4): 393-398. 牧野佐二郎. 1982. 放射線·化学物質と染色体異常[D]. 医学書院.
