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