Xenochroa careoides Warren
Aiteta careoides Warren, 1912, Novit. zool., 19: 38.
nigrimacula Kobes, 1997: 136, syn. n.


Xenochroa careoides

The forewings are a diffusely variegated rich light brown with an oblique curved antemedial fascia and a postmedial that is distinctly angled subcostally after diverging from the antemedial commencing at the dorsum. There is a diagnostic black triangle at the dorsum just basal to the antemedial and also a submarginal row of small black dots.

Taxonomic note. Kobes used the infrasubspecific name of careoides ab.
nigrimacula Warren for his new species, but did not distinguish it from careoides in his diagnosis. The type of careoides (Penang) is worn but lacks the black triangle; another specimen has it reduced. The male genitalia of the two forms are identical. The species has a relatively elongate aedeagus vesica, a more prominently swollen ventral part of the tegumen on each side, and a distinct border of black setae on the dorsal margin of the distal part of the valve. X. perspicua Prout comb. n. (Seram, Sulawesi) has similar forewing facies and is probably the sister-species of careoides.

Geographical range. Peninsular Malaysia, Sumatra, Borneo, Palawan (ZMUC), Andamans, Hainan.

Habitat preference. Three specimens have been taken in lowland dipterocarp forest (Labi and Ulu Temburong) and one in heath forest (Telisai), localities at or below 300m in Brunei. One was taken in lower montane forest at 1000m on G. Mulu.
