The uncus lobes of E. bruuni are narrow, reminiscent of those of E. nitidulella; the cornuti are larger than those of E. distigmatella and smaller than those of E. dispilella. Elachista bruuni is easiest to distinguish from E. nitidulella by their outer appearance; E. nitidulella is smaller, the forewing unicolorous dirty white, and the hindwing darker grey than in E. bruuni. The male genitalia of the two are similar; the valva is a little longer and the cornutus group larger in E. bruuni than in E. nitidulella. The juxta lobes are strongly produced laterally in E. bruuni, not so in E. nitidulella. For female genitalia, see the key. Molecular characterization. The analyzed seven ...
