A total of 6 species of the Pyretophorus (4 species) and Neomyzomyia (2 species) series of the subgenus Cellia of Anopheles were used for metaphase karyotype analysis. Anopheles subpictus and An. vagus exhibit 4 and 2 forms of mitotic karyotypes, respectively, which are attributable to different types of Y chromosomes. Such distinctive mitotic chromosomes may reflect interspecies differences within each of these 2 taxa. Two distinct species, An. indefinitus and An. sundaicus, show similar metaphase karyotypes, particularly with regard to the size and shape of the sex chromosomes. Likewise, An. tessellatus and An. kochi, which are distinct species of the Neomyzomyia Series, also have metaphase karyotypes that resemble each other. They exhibit a typical feature of telocentric sex chromosomes resembling those of the An. dirus complex and the other species of the Leucosphyrus Group. Like the other cases of the Oriental Anopheles, heterochromatin has played a significant role in chromosome evolution of the 6 species.
总共6种按蚊亚属Cellia的疟蚊亚组（4种）和新疟蚊亚组（2种）用于中期核型分析。伪威氏按蚊和迷走按蚊分别表现出4种和2种有丝分裂核型形式，这归因于不同类型的Y染色体。这种独特的有丝分裂染色体可能反映了这两个分类单元中每个分类单元内的种间差异。两个不同的物种，不定按蚊和辛德按蚊，显示出相似的中期核型，特别是在性染色体的大小和形状方面。同样，新疟蚊亚组的两个不同物种，多斑按蚊和高氏按蚊，也具有彼此相似的中期核型。它们表现出端着丝粒性染色体的典型特征，类似于大劣按蚊复合体和白跗按蚊组的其他物种。与东方按蚊的其他情况一样，异染色质在这6个物种的染色体进化中发挥了重要作用。
