The N. bana species-group

Diagnosis. The coloration and the pattern are similar to those of the N. sumatrana species-group. The male genitalia of the species group are similar to those of the N. pusilla species-group, but the valve is significantly narrower distally (the character found also only in N. gulmargensis species-group), the subapical saccular process is reduced and presented as a small rounded protrusion, and the apical costal lobe is heavily sclerotized, elongated, thorn-like, apically pointed, whereas in the species of the N. pusilla species-group is shorter the apical costal lobe is shorter and apically rounded or tapered.
