Xanthanomis
vomeroi Holloway & Zilli sp. n.
 ,  18-20mm. This species is larger than fuscifrons,
with a more irregular forewing margin and a more rounded hindwing one. The
ground colour is more a dull, pale orange, with the more purplish zone distal to
the fasciae only slightly (rather than abruptly) darker. The reniform is
conspicuous, dark brown. The pale submarginal markings are also more
conspicuous, ovate rather than lunulate, two and a smaller one at the forewing
apex, and three at the hindwing dorsum. The male genitalia have a shorter uncus.
The valves are straight, rather than outturned, and much more robust with a more
complex array of small processes subbasally.

the band of sclerotisation in the bursa is very much longer than in fuscifrons.
