摘要

根据多腺染色体的形态，确定了保加利亚的 21 个摇蚊属物种。图中展示了每个物种的多腺染色体原始图片。多腺染色体的每个臂都确定了 "基本 "序列，用于确定染色体的相应臂和物种所属的细胞复合体。这些物种分布在五个细胞复合体中：thummi、pseudothummi、parathummi、lacunarius 和修饰的 thummi 细胞复合体。染色体 G 上的标记序列已被发现，建议将其作为物种识别标志。研究还讨论了摇蚊属同序物种的细胞遗传学特征。这项研究强调了多体染色体对摇蚊物种分类的重要性。

Markers in the polytene chromosomes of freshwater Chironomus Meigen (Diptera, Chironomidae) species

Based on the morphology of the polytene chromosomes, 21 species of the genus Chironomus Meigen from Bulgaria have been identified. Original pictures of the polytene chromosomes are presented for each species. “Basic” sequences were determined for each arm of the polytene chromosomes which are used to determine the corresponding arms of the chromosomes, and the cytocomplex to which the species belongs. The species are distributed in five cytocomplexes: thummi, pseudothummi, parathummi, lacunarius and modified thummi cytocomplexes. Marker sequences have been revealed on chromosome G that are proposed as a species identifier. Cytogenetic characters by which homosequential species of the genus Chironomus can be distinguished are discussed. This study emphasizes the importance of polytene chromosomes for the taxonomy of the species of Chironomus.

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
