The sequence of a 595-bp fragment of the mitochondrial COI gene was determined for the species Chironomus usenicus and Chironomus curabilis of the genus Chironomus. Phylogenetic reconstructions based on the analysis of the COI gene sequence coincide on the whole with cytogenetic data, permitting Ch. usenicus and Ch. curabilis to be regarded as members of the group plumosus. Chironomus usenicus and Ch. plumosus have identical COI gene sequences. Two hypotheses explaining this identity are considered: inheritance of mtDNA from one of the parental species during hybridogenesis and horizontal transfer of mitochondrial genes.
测定了摇蚊属的乌森摇蚊和可治愈摇蚊线粒体COI基因595个碱基对片段的序列。基于COI基因序列分析的系统发育重建总体上与细胞遗传学数据一致，使得乌森摇蚊和可治愈摇蚊被视为羽状摇蚊组的成员。乌森摇蚊和羽状摇蚊具有相同的COI基因序列。考虑了两种解释这种同一性的假说：杂交发生过程中从亲本物种之一继承线粒体DNA以及线粒体基因的水平转移。
