Description

The genus Parachironomus has a cosmopolitan distribution including 85 valid described species worldwide. Species records and studies of the genus in the Tibetan Plateau are scarce. In this study, the genus Parachironomus from China is revised and two new species, Parachironomus wangi Liu & Lin, sp. nov. and Parachironomus nankaiensis Liu & Lin, sp. nov., are described based on adult morphology and molecular data. Paracladopelma demissum Yan, Wang & Bu is placed in the genus Parachironomus as a new combination. A neighbor-joining tree was reconstructed based on all known Parachironomus COI DNA barcodes. A key to adult males of the genus Parachironomus from China is also provided.
