Larval morphology and polytene chromosomes of Chironomus anthracinus from eastern Kazakhstan have been described. Larvae have no lateral tubules on VII abdominal segment, but have paired ventral tubules on VIII abdominal segment. 2 n = 8 (A1.1 B1.1 C2.2 D1.1 E1.1 F1.1 G1.1). Two nucleoli are present in arms IVG and IIIF. Mapping of chromosomes, apart from antC2 arm, was performed after Shobanov (1996). B-chromosomes have been discovered in this species for the first time (in 19.4% individuals). Heterozygous inversions occurred in arms LA and IIIE in 46% of individuals. Compared to C. anthracinus from Yaroslavl Region, differences in morphology and karyology observed in this species from eastern Kazakhstan are related to habitation of the population examined in the deep-water Lake Markakol on the boundary of the area range.
已对来自哈萨克斯坦东部的炭疽摇蚊幼虫形态和多线染色体进行了描述。幼虫在腹部第七节没有侧管，但在腹部第八节有一对腹管。2n = 8（A1.1 B1.1 C2.2 D1.1 E1.1 F1.1 G1.1）。在IVG和IIIF臂中有两个核仁。除了antC2臂外，染色体图谱绘制是根据绍巴诺夫（1996年）的方法进行的。首次在该物种中发现了B染色体（在19.4%的个体中）。在46%的个体中，LA和IIIE臂出现了杂合倒位。与来自雅罗斯拉夫尔地区的炭疽摇蚊相比，在哈萨克斯坦东部该物种中观察到的形态学和核型差异与在该区域边界深水马尔卡科尔湖所研究种群的栖息地有关。
