Taxonomy. Theshapeandcolourationoftheforewingareverysimilar to those of N. fuscicosta (Hampson, 1891) and also similar to those of N. acolutha Holloway, 2008 and N. lancanga DengetHan, 2011 but, accordingtothe malegenitalia, N. vicina isamemberofadistinctlineagerathercloserto N. glauculalis.
Description. Wingspan 19–21 mm, lengthofforewing 9–10 mm. Themaleantenna lessspecialised, moreorlessfiliformwithshortfasciculateciliaandflatdorsalscales; femaleantennafiliform, verysparselyciliate.

Diagnosis. Thewingpatternof N. vicina isconfusinglysimilartothatof N. fuscicosta, althoughthefiliformantennaof N. vicina andtheconspicuously pectinateantennaof N. fuscicosta caneasilydistinguishthemales. Naardalancanga hasalsoverysimilarpattern, butlacksthedarkareaclosetodorsum, whichispresentin N. vicina. Moreover, theinnermostfasciaonthehindwing of N. vicina issinuous, whilein N. lancanga itisratherstraight. Thenewspeciesdiffersexternallyfrom N. acolutha bytheabsenceofthedarkfieldatposteriorsectionoftermen, andbytheconspicuouslylighterterminalfieldofthe hindwing.
