Macrocheraia is a genus of bug in the family Largidae with a single species, Macrocheraia grandis found mainly in Southeast Asia but extending into parts of South Asia. This was referred to in some older literature under the genus Lohita, a name derived from the Sanskrit word for red. The abdomen of the male is long and extends well beyond the wingtip. The species feeds on a range of plants including those of the families Euphorbiaceae and Malvaceae.
