Abstract

A new free-living genus of the mycophagous tribe Brachineurini, Loborrhizomyia gen. nov., and its type species (Loborrhizomyiaphaneroectata sp. nov.) and another new species (Loborrhizomyia aphanata sp. nov.) are described from the Caiyang River NatureReserve, Pu’er, Yunnan, China. The new genus is characterized in the tribe Brachineurini by the unique gonostylus having a ventral lobeprotruding to the distal. The taxonomic status of the new genus and two new species is discussed with a comparison between the otherrelated groups and an updated key to all known Brachineurini genera including the new genus is provided.
