the previous species and the next are very similar in their general pattern,
and they can also be variable in variegation and, more rarely, in having
patches of pale mauve-grey in the medial area. In Sundaland, subsignata is a paler, much
less violet brown than the other two species, with the medial band standing out
much darker. The postmedial fascia of the hindwing is more conspicuously picked
out with pale edging on the upperside, but on the underside the fascia interior
to this postmedial extends more weakly to the costa than in martina and is more
often interrupted by a pale discal spot. The male genitalia are similar to
those of martina but, for a similar sized moth, relatively much
smaller with the uncus slightly more slender and of more even width. The
falcate flange at the apex of the valve is erect and narrow compared with that
note. Berio & Fletcher (1958) noted that the type of subsignata (Singapore)
could not be located in BMNH or in Oxford Univ. Mus. Poole (1989) retained it
as a good species within Sypna. The species discussed here matches a
short series over the name subsignata in BMNH; this includes the specimen from Dinding
referred to by Swinhoe (1900, Cat. Lep. Het. Oxford Univ. Mus. 2: 106, 592),
who related subsignata to his new species, samala Swinhoe, which
is based on a female of S. albilinea Walker (see above).
The original description of subsignata, particularly of the underside, seems
to be significantly different to the species treated here. Therefore the latter
is described as new, above.

specimens were recorded from lowland heath forest on a river terrace at 170m
near the Melinau Gorge during the Mulu survey.
