Abstract
Three new species of the predaceous midges of genus Alluaudomyia Kieffer, 1913: A.flavinotum Wu & Li, sp. nov. of the maculipennis group, and A.reflexuralis Wu & Li, sp. nov. and A.limu Wu & Li, sp. nov. of the parva group, are described from the National Park of Hainan Tropical Rainforest, Hainan Island, China. Illustrations and COI barcodes (a fragment of the mitochondrial cytochrome c oxidase subunit 1) of the three new species are also provided. Associations of male and female specimens of two species (A.reflexuralis Wu & Li, sp. nov. and A.limu Wu & Li, sp. nov.) are supported by DNA barcodes. The parva group is reported from China for the first time.
