Two new species of (Diptera, Chironomidae) from Oriental China, delineated with morphology and COI sequences.

Two new species, Macropelopia (Macropelopia) excavata Xu & Fu, and Macropelopia (Macropelopia) quadrimacula Xu & Fu, , are described as male adults. A key to identify the males of from China is provided. Furthermore, in order to ascertain the genetic distance between these species and their morphological characteristics, mitochondrial cytochrome oxidase subunit I gene sequences were uploaded to the National Center for Biotechnology Information.
