A new brachyceran fly (Diptera: Tabanomorpha), Pseudorhagio zhangi gen. et sp. nov., is described from Late Cretaceous Burmese amber. It is tentatively placed as Family incertae sedis in Tabanomorpha and distinguished from other Tabanomorpha by the following unusual combination of characters: head wider than thorax; body densely covered with fine and short setae, devoid of macrosetae; scutum strongly convex, nearly spherical; scutellum rather small, convex; antennal flagellum elongated, tapering, unsegmented; vein R4 perpendicular to R5, and strongly curved; crossvein m-m very long, strongly sinuated; tibial spur formula 0, 2, 0. This discovery further confirms the high diversity of Tabanomorpha in Late Cretaceous Burmese amber. An updated list of brachyceran species in Burmese amber is given.
