, 16-18mm. 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.

Geographical range. Borneo.

Habitat 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.
