The genus Rhaphium Meigen, 1803 is recorded for the first time from mangroves in Hong Kong. Three species are described as new to science: Rhaphium hongkongense sp. nov. and Rhaphium spinulatum sp. nov., both tentatively belonging to the Rhaphium crassipes group sensu Negrobov & Grichanov (2010), and Rhaphium canniccii sp. nov. assigned to a new species group, the Rhaphium micans group. The status of Rhaphium mediocre (Becker, 1922) described from Taiwan and Rhaphium eburnea (Parent, 1926) from Shanghai is discussed. NGS barcodes for the new species are provided.
