The genus Rheotanytarsus Thienemann & Bause, 1913 (Diptera: Chironomidae) currently includes more than 120 recognized species worldwide, but precise species-level identification based solely on morphology remains challenging. Pronounced morphological differences among life stages and the time-consuming inefficiency of rearing larvae further complicate life-stage matching in this genus. In study, we assessed diversity by integrating examination DNA barcoding, analyzing 911 barcodes from newly collected samples a public database. Based these results, constructed relatively complete life-history framework. Our results show that belong to 69 putative species. maximum intraspecific divergence reached 7.35% R. pentapoda, average minimal interspecific distance was 11.44%. Substantial certain complexes suggests presence cryptic Therefore, resolve potential issues, extensive sampling specimens geographically distant regions—supplemented nuclear ecological data—are required.
