Chironomidae, with over 7,300 described species, are amongst the most diverse and abundant insect families in freshwater ecosystems worldwide. Chironomids are known for their widespread distribution from various water types. The level of documentation of chironomid fauna varies considerably amongst European countries, with more comprehensive knowledge for Western Europe compared to other regions. Despite the recent extensive sampling effort and the increasing number of available data, the chironomid fauna of Central European countries still remains poorly known.
This study contributes to the knowledge of chironomid fauna in three river catchments in Croatia, Hungary and Czechia. A combination of morphological and molecular techniques was employed, with a focus on larvae, although pupae and exuviae were also examined. We found 207 taxa, amongst which 170 were identified to species level. In Croatia, 14 species were recorded for the first time and two species were newly recorded in Czechia. DNA barcoding of 31 specimens resulted in 23 BINs, including eight new ones to BOLD. We provided detailed notes on taxa with taxonomic problems and/or morphological peculiarities. Our results highlight that extensive studies conducted in relatively small areas and a limited range of habitats (only streams in hilly regions) can remarkably contribute to the local and global knowledge on Chironomidae fauna, especially when the taxonomically difficult and often problematic larvae are investigated.
摇蚊科有超过7300种已描述的物种，是全球淡水生态系统中最多样化且数量丰富的昆虫科之一。摇蚊以其在各种水体类型中的广泛分布而闻名。欧洲各国对摇蚊动物群的记录程度差异很大，与其他地区相比，西欧的了解更为全面。尽管最近进行了广泛的采样工作且可用数据不断增加，但中欧国家的摇蚊动物群仍然鲜为人知。
本研究有助于了解克罗地亚、匈牙利和捷克的三个河流集水区的摇蚊动物群。采用了形态学和分子技术相结合的方法，重点关注幼虫，不过也对蛹和蜕皮进行了检查。我们发现了207个分类单元，其中170个被鉴定到种级水平。在克罗地亚，首次记录了14个物种，在捷克新记录了2个物种。对31个标本进行的DNA条形码分析产生了23个BINs，包括8个在BOLD上的新BINs。我们提供了有关分类学问题和/或形态学特征的分类单元的详细注释。我们的结果表明，在相对较小的区域和有限的栖息地范围（仅山区溪流）内进行的广泛研究可以显著促进对摇蚊科动物群的本地和全球认识，特别是在研究分类困难且往往有问题的幼虫时。
