7mm. The male antennae are fasciculate. The forewing has a narrow medial whitish
triangle based on the dorsum and extending somewhat obliquely distad and towards
the costa. The rest of the wing is a finely mottled dark dull brown and fawn.
The apodemes of the eighth segment are close together and with strong venulae as
in coremata, but the coremata-like structures are more basal on the
abdomen, flanking the apodemes of the basal sternite. The genitalia have the
valves rather apressed to the tegumen, moderately cleft, but with the basal arm
very narrow relative to the dorsal one. The harpe is broad, upcurved, tapering
to a point. The aedeagus is unusual in having the vesica almost completely
covered by short, robust, broadly based spines. The genitalia indicate that the
species may be allied to
N.
sakishimana
Inoue (2001) from the Ryukyu Is (Okinawa), but this is a more white and purplish
black species with more clearly defined fine white fasciation in the dark areas.
The male has narrowly bipectinate antennae. The species is also close to
N.
rufimixta
Hampson (Sri Lanka) where the forewing is much paler, with a clearly defined,
double, brown antemedial and paler fasciae within a browner marginal zone. There
are three plates of raised scales along the forewing cost as in marginata
Hampson (see below; these are more irregular in spinivesica). The male
abdomen of rufimixta is very similar, including the basal coremata, but
the harpe is more tapered and acute.
