Metaphase karyotypes of 9 species of the Myzomyia Series show intra- and interspecific differences based on quantitative variation and distribution of constitutive heterochromatin in the sex chromosomes or the centromeric regions of the autosome pairs or both. Anopheles jeyporiensis and Anopheles aconitus each exhibit 4 forms of mitotic karyotypes, which may reflect interspecific differences within each taxon. The well-defined genetic species within the Anopheles minimus and the Anopheles culcifacies complexes clearly exhibit distinctive metaphase karyotypes that can be used as diagnostic characters for separating these sibling species, which are difficult to identify by morphological criteria alone. Our analysis on metaphase karyotypes of Anopheles pampanai, Anopheles varuna, and Anopheles flavirostris also confirms their morphological identification based on heterochromatin differences in the sex chromosomes and autosome 2.
疟蚊亚属9个物种的中期核型显示，基于常染色质在性染色体或常染色体对的着丝粒区域或两者中的数量变化和分布，存在种内和种间差异。杰氏按蚊和乌头按蚊各自表现出4种有丝分裂核型，这可能反映了每个分类单元内的种间差异。微小按蚊复合体和库氏按蚊复合体内明确的遗传物种明显表现出独特的中期核型，可作为区分这些同胞物种的诊断特征，仅靠形态学标准很难识别这些同胞物种。我们对潘氏按蚊、瓦氏按蚊和黄喙按蚊中期核型的分析也证实了基于性染色体和第2号常染色体上异染色质差异的形态学鉴定。
