The karyotypes and the localization of C-bands, clusters of ribosomal DNA and telomeric repeats of 10 species of the family Pamphagidae from Morocco are described for the first time. The species studied belong to the subfamilies Pamphaginae and Thrinchinae. All species have karyotypes consisting of 19 and 20 acrocentric chromosomes and X0/XX sex chromosome system in males and females, respectively (2n♂=19, NF=19; 2n♀=20, NF=20). Despite the karyotype conservatism, we revealed differences in the location and size of C-heterochromatin blocks and ribosomal DNA clusters. A comparative analysis of these differences shows that karyotype divergences in this group is connected not to structural chromosome rearrangements, but to the evolution of repetitive DNA.

摩洛哥Pamphagidae蚱s染色体中C-异染色质，核糖体和端粒DNA标记的比较分析。

首次描述了来自摩洛哥的10个Pamphagidae家族的核型和C带，核糖体DNA簇和端粒重复序列的定位。所研究的物种属于Pamphaginae和Thrinchinae的亚科。所有物种的核型分别由雄性和雌性的19个和20个近端染色体和X0 / XX性染色体系统组成（2n = 19，NF = 19； 2n = 20，NF = 20）。尽管有核型保守性，我们揭示了C-异染色质嵌段和核糖体DNA簇的位置和大小的差异。对这些差异的比较分析表明，该组的核型差异与结构染色体重排不相关，而与重复DNA的进化有关。
