Sundaroa sexmacula

Diagnosis and taxonomic note.
Both wings are yellow with broad basal black areas. The forewing has subapical and subdorsal black spots, distinguishing it from females associated with transflava Holloway (See Sundaroa transflava Holloway comb.n) where a single spot is centrally submarginal. The taxon is represented only by females which may be those of celaenostola Collenette, discussed next. These marriages are tentative, in that a reverse assignation is plausible, hence a formal synonymy must await evidence from rearing or pairs found in copula. If confirmed, sexmacula would have priority over celaenostola. Support for the association suggested is found in the position and size of the discal spot, and the possibility that the subtornal black spot correlates with the black insert to the oblique pale bar of celaenostola.

Geographical range. Borneo.

Habitat preference. The species appears to be commoner than the other female form but, like it, is only recorded from the Kinabalu area. No altitude data are available, those noted by Holloway (1976) being of the other female form.
