Holotype condition. Left wing detached, mounted on microslide. Left postpedicel glued on the specimen triangle card. Terminalia placed in microvial with glycerin.

Etymology. The specific epithet is a patronym honoring Francisco Limeira de Oliveira, curator of CZMA, from Universidade Estadual do Maranhão.

Distribution. Brazil: Maranhão (Cerrado Biome).

Discussion. Elmohardyia limeirai sp. nov. is close to E. potiguar sp. nov., due to the left surstylus with apex curved inward, sternite 6 with two subapical protuberances, membranous area longer than wide, and phallic guide with two additional processes. Elmohardyia limeirai sp. nov. differs from E. potiguar sp. nov. by the thinner distal half of the left surstylus (broader in E. potiguar sp. nov.), right surstylus with base wider than apex (almost equally wide in E. potiguar sp. nov.), and left gonopod not developed (short but distinct in E. potiguar sp. nov.).
