| 摘 要： | 本文记载了中国25种角蝉的染色体，研究表明染色体的数目、大小及其在减数分裂过程中的行为具有种或属一级的分类特征。该科昆虫染色体的数目变异在n＝5到12之间，众数为n＝11，另外，n＝10的类型也较为普遍。绝大多数种类的性别决定机制为XO型，仅个别种类具有新XY性染色体系统。

| Abstract: | Chromosomes in 25 species of Membracidae are recorded. Numbers, size and behaviors of the chromosomes during meiosis and mitosis are used as specific or generic features for the taxonomy of this group. Chromosome numbers vary from n= 5 to 12, and sex mechanism are of XO type except two species with neo-XY system. The histogram indicates that 2n=11 with XO sex mechanism is the modal chromosome number, and another type n= 10 is also commonly found in this family. |
