Diagnosis. Theshapeandsizeofforewingofthisnewspeciesaresimilar to N. ineffectalis sensuHolloway, 2008. But N. huettleri lacksthemalebasal scentorganofforewing, whichispresentin N. ineffectalis sensuHolloway, moreover, theorbicularspotislarger.

Thesupposedclosestrelativeof N. huettleri is N. secreta . However, N. huettleri differsfromthelatterbythesomewhatnarroweruncus, narrower valvaandthemorecurvedapicalfusedstructureofvalva.
