Aims:The main aim of this study was to fill a gap in barcoding data of the European Chironomidae of the Balkan region, developing and testing the efficiency of a reference DNA barcode library for ancient Lake Skadar basin species (Montenegro/Albania), a region of Europe never before subjected to barcoding studies on Chironomidae.Another aim was to test the efficiency of DNA barcoding for the identification of European Chironomidae, including the estimation of optimal identification thresholds, using >12,000 barcodes.Location: Lake Skadar basin and adjacent area (Montenegro/Albania).Methods: Through this study, 770 individuals of Chironomidae from the Lake Skadar region were barcoded, both at adult and pre-imaginal stages. Adults were morphologically identified, while larvae were assigned to species by molecular identification, using different methods, of which the efficiency was tested, for a total of 97 different barcoded species. Results:The identification efficiency of the reference dataset developed for the Lake Skadar region was 98.6%, a value in line with that obtained when the identification efficiency for European Chironomidae was evaluated (95.8%), which confirms the accuracy of DNA barcoding for the identification of these insects. Moreover, we found that the optimal threshold for the molecular identification of the family is 1.6% nucleotide distance, though more specific thresholds are suggested for the identification of species belonging to Chironomidae subfamilies, since they are related to lower identification errors than to the use of a general threshold. The analysis of inconsistency between molecular and morphological identification shed light on taxonomic issues within European Chironomidae. Previously postulated species synonyms were confirmed, and also further cases requiring deeper investigation were detected.Main conclusions: Our de novo DNA barcode library was shown to have a high identification efficiency. Taxon-specific thresholds increase the efficacy of molecular identification. Hypothesized species synonyms could be validated through molecular techniques.

“…Chironomus striatipennis Kieffer (Diptera: Chironomidae) is widely distributed in Holarctic, Oriental and Neotropical regions; its larvae frequently present in oligotrophic to eutrophic freshwater, such as lakes, swamps, rivers, sewage ditches, fish ponds and rice fields; it is regarded as an alien species to America derived from Asia by unintentional human transport (Al-Shami et al, 2012;Amora et al, 2015;Martin, 2017) (Figure 1). C. striatipennis is widespread in China (Wang et al, 2020); we had ever found its larvae infected municipal water systems in several cities in South China.…”

Chironomid is the most important macroinvertebrate species in aquatic ecosystem. Chironomus represents the most important genus of the Chironomidae. However, the species of this genus lack a high-quality assembled genome. Here, a high-quality chromosome-level assembled genome of Chironomus striatipennis which is an important model organism in aquatic ecological detection and toxicological application has been reported. The assembled genome size of C. striatipennis was 181.84 Mb, with a scaffold N50 value of 54.13 Mb. Furthermore, the molecular mechanism of adaptive evolution of Chironomid to benthic environment was elucidated by combining transcriptome data of different stages. The complete metabolic pathway of Hemoglobin was clarified in C. striatipennis for the first time to suggests the regulatory mechanism underlying its adaptation to benthic living. The expansions of CYP450s gene family related to detoxification explain its tolerance to the harsh environment. The key gene family, JHAMT, involved in biosynthesis of juvenile hormone are substantially expanded. The expansion of JHAMT genes and the regular regulation of juvenile hormone and ecdysone explain the developmental plasticity of C. striatipennis. In this study, it was also found that C. striatipennis is more dependent on JNK signal pathway induced metamorphosis than Drosophila melanogaster. This study provides some views into genetic basis of tolerance and adaptation of C. striatipennis to harsh benthic environments and lays a part of the foundation for the adaptive evolution of benthic animals.
