The Rheotanytarsus guineensis species group (Diptera: Chironomidae) is a species diverse and taxonomically difficult group. Using DNA barcodes, we found five new species within the R . guineensis species group and reviewed the species group based on adult males from China. Rheotanytarsus guoae Lin & Yao sp. n ., Rheotanytarsus miaoae Lin & Yao sp. n ., Rheotanytarsus qiangi Lin & Yao sp. n ., Rheotanytarsus yueqingensis Lin & Yao sp. n ., and Rheotanytarsus yui Lin & Yao sp. n . are all described and figured. A key to known adult males of the R . guineensis species group worldwide is provided for the first time.
