The ovarian nurse cell's polytene chromosomes of An. minimus exist as 5 arms, the telocentric X chromosome, the submetacentric chromosome 2 and the metacentric chromosome 3. The X chromosome is easily recognized by its length and shuttle-shaped zone 6. The most important characteristics is that each autosome arm has one to three big puffs. Among the 46 zones, 7A, B and 19C in 2R which is the longest arm in the complement, 28A and 20A, B in 2L, 30A, B and 37D in 3R and 46D and 38A, B in 3L are considered as characteristic zones. It is proposed that this map might be considered as the "standard" map of the ovarian nurse cell's polytene chromosomes for An. minimus from Guangxi.
微小按蚊卵巢滋养细胞的多线染色体呈现为5条臂，即端着丝粒X染色体、亚中着丝粒染色体2和中着丝粒染色体3。X染色体很容易因其长度和梭形的6区而被识别。最重要的特征是每条常染色体臂都有一到三个大的胀泡。在46个区中，2R（补体中最长的臂）上的7A、B和19C，2L上的28A和20A、B，3R上的30A、B和37D以及3L上的46D和38A、B被视为特征区。有人提出，这一图谱可被视为广西微小按蚊卵巢滋养细胞多线染色体的“标准”图谱。
