Diagnosis. Theunusuallybroadforewingofthisnewspeciesisshared by N. blepharota ( Strand, 1920)   . Naardasecreta isslightlysmallerinsizethan N. blepharota   , thegroundcolourisdarker, thereniformstigmaislighterand smaller, andthestreaksoftheterminallinearemuchmoreelongate. Themale genitaliashowmoreconspicuousdifferencesbetweenthesetwospecies: the ventraledgeofuncusin N. secreta   isstraight, whilethatof N. blepharota   ( Fig. 7 View Figs 7–12 ) has an emergence, the juxta is broader, the valva has no harpe, but the costa hassmalllobe, whichisabsentin N. blepharota   .
