Taxonomy.

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 bytheabsenceofthedarkfieldatpos- teriorsectionoftermen, andbytheconspicuouslylighterterminalfieldofthe hindwing.
