Dialectica galapagosensis
The orange forewings and white markings easily separate this species from the other Galapagos Gracillariidae except Dialectica sanctaecrucis darwini. In Dialectica galapagosensis the apical 1/3 of the forewing is crossed by two transverse white bands while that of Dialectica sanctaecrucis darwini has one slender, subterminal, transverse white band connected posteriorly with a larger longitudinal band running along apical 1/4 of dorsal margin (Landry, 2006).
