The forewing length of N. mondika is 14–16 mm in males and 18–21 mm in females. Based on its extensive creamy-white forewing markings and the postmedial patch fully fused with the subterminal band, this species is readily distinguished from all other taxa of the genus, being most similar to N. divergens where the distinctive morphological characters are discussed in the diagnosis of the latter species. Bionomics and distribution. The overwhelming majority of N. mondika was sampled in the pristine Congolian lowland rainforest habitats of Nouabalé-Ndoki National Park with Gilbertiodendron dewevrei stands nearby. The species seems to be on the wing exclusively in the dry season and especially frequent in the short dry season in February. Two specimens have been traced from Gabon and Cameroon displaying morphological characters matching well with the topotypical population suggesting that N. mondika likely occurs in a wider area of central Africa.
