In this study, the genusParachironomusfrom China is revised and two new species,ParachironomuswangiLiu & Lin,sp. nov.andParachironomusnankaiensisLiu & Lin,sp. nov., are described based on adult morphology and molecular data.ParacladopelmademissumYan, Wang & Bu is placed in the genusParachironomusas a new combination. A neighbor-joining tree was reconstructed based on all knownParachironomusCOIDNA barcodes. A key to adult males of the genusParachironomusfrom China is also provided.
