Abstract
Brahmina Blanchard,1851 is a minor genus in Melolonthinae and is composed of 76 species assigned into three subgenera.Here a new species of Brahmina is described as new to science from Liaoning:Brahmina(Brahmina)haitangensis Zhang sp.nov.Sexual dimorphism is discovered in Brahmina for the first time:clypeal notch absent in male but present in female;male antennal club longer than the total length of the third to the seventh antennomere,while the female antennal club shorter than those antennomeres;both metaspurs slender in male,but the lateral metaspur expanded in female.
