Diagnosis. The
forewing border is broad, enclosing deep red, and with a single indentation in
its basal margin.
Taxonomic note. The
holotype of dentata was described as male but is female, not
distinguishable from the female of plumosus, which may itself be merely a
race of the Himalayan S. tricolor Walker. In Sumatra flies the only
Sundanian member of the fourth genus of the group discussed by Holloway (1984b),
Neoscaptia Hampson (type species collateralis Hampson, New Guinea
= collaris Strand), a subspecies of the more easterly N. calida Walker,
ssp. tenuis Rothschild & Jordan. Its conspecificity with calida and
generic placement need examination but the male genitalia lack the setae
characteristic of Scaptesyle. Externally it is very similar to plumosus
and may prove to occur also in Borneo, but confirmation is best made on male
genitalic characters rather than facies, though the hindwing borders are
generally more extensive.
Geographical range. Sumatra,
Java, Peninsular Malaysia, Borneo.
Habitat preference. The
species has been recorded flying by day infrequently from the coast at Seria in
Brunei to as high as 1660m on G. Kinabalu.
