This species is a member of a complex otherwise restricted to the Philippines,
currently totalling five (Cernư, 1993), such as euryxantha Hampson and lunulata
Semper. The forewing markings tend to be a paler, yellower orange than in conclusa
and the next two species, and males lack an orange wedge between the double
black discal dot and the antemedial. The male genitalia are characterised
particularly by the aedeagus, where the anellar ring is finely and densely
scobinate but the vesica is small and lacks ornamentation. The valves have no
additional spurs or ridges, the dorsal and saccular processes being simple. The
female genitalia have a corrugate zone in the appendix bursae (seen also in some
other species groups); there is no signum. C. maiae has the double black discal mark transverse, the two
components separate, whereas in Philippines species the two components are
fused, and the more posterior one is displaced or extended basad. The subbasal
fascia lacks the black edging to its distal margin seen in all Philippines
species. In the male genitalia the valve costa has a diagnostic angle at one
third, and the spine at the apex of the sacculus is much more strongly flexed,
angled rather than curved, complared to the Philippines species.

preference. Records
are over a similar ecological range to
perornata and malayensis Hampson, but maiae was
taken in particularly high numbers on the limestone G. Api, from its foot to the
lower montane zone at 900m.
