摘　　要：采用姬姆萨染色压片法 ,对花蝽科山地原花蝽性细胞进行了核型研究。结果表明该种单倍染色体组成为n =14A+XY ,为无交叉减数分裂 ,性染色体经历后减数分裂 ,上述核型特征为阐明臭虫型内不同科的系统发育关系具有重要意义。The karyotype of Anthocoris montanus Zheng (Anthocoridae, Heter optera, Cimicomorpha) is described in detail for the first time through the use of Giemsa staining and “squashed' slides. The species displays the chromosome c o mplement n=14A+XY, and sex chromosomes undergo post-reductional meiosis. M oreo ver, male meiosis is achiasmatic in this species. This feature is significant in clarifying phylogenetic relationships among families of the Cimicomorpha for th e future.
