Xanthanomis xanthina Holloway & Zilli sp. n.
17-18mm. This species is a similar size to fuscifrons, but has a much stronger, brighter ground colour. Some females of fuscifrons may also be a stronger yellow, but those of the new species tend to have the pale lunules at the hindwing tornus more conspicuous, and the orbicular is more distant from the more distinctly rufous foreiwng antemedial. The stronger yellow colour is seen also in species such as aurantiaca Hampson from the New Guinea area and undescribed relatives from the Philippines and Sulawesi. These tend to be much larger than the Sundanian species. In the male genitalia the valves are shorter than in fuscifrons and later the exteriorly directed apical projection. There is an acute process just interior to the central convexity of the ventral margin (not present in fuscifrons and aurantiaca; the ventral margin in the latter is straight rather than sinuous) and a setose process dorsal and basal to that that is broader and more outwardly directed than its homologue in fuscifrons. The aedeagus has a lateral spine subapically as in other members of the aurantiaca group but more basal and not slightly serrated. In the female genitalia, the eighth segment has more numerous setae and the ostium and basal part of the ductus are very much broader than in fuscifrons or aurantiaca.
