Nola spinivesica sp. n.


Nola spinivesica

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.
