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) has an emergence, the juxta is broader, the valva has no harpe, but the costa hassmalllobe, whichisabsentin N. blepharota.
Themalegenitaliaofthisnewspeciesaresimilartothoseof N. atrata. However, thecostallobeofthevalvaof N. secreta isabsentfrom N. atrata, moreover, thevalvaislesstapering, itstiproundedinsteadofbeingpointedas in N. atrata, thesaccusisbroaderandthecornutusinthevesicaisalsobroader.
