Acidalia nigropunctata Guenťe
[nec Hufnagel], 1857, Hist. nat. Insectes, Spec. Gen. Lep., 9:
Lycauges annularia Swinhoe,
1890, Trans. ent. Soc. Lond., 1890: 214.
Scopula reducta Rothschild, 1920, J. Fed. Malay States Mus.
Diagnosis. This and Scopula planidisca
Bastelberger are distinguished by an enlarged black- ringed
discal spot on the hindwing. S. annularia is larger, with a straighter
oblique postmedial on the forewing. Black flecks in the forewing submarginal and
hindwing postmedial tend to be longitudinal in annularia and transverse
in planidisca Bastelberger. The latter has the fascia basal to the
hindwing disc more strongly blackened.
Taxonomic note. The cerata in specimens from the Himalaya to Sumatra are unequal in
length, one very short, more or less reduced to the terminal tuft of setae. In
Bornean and Sulawesi material both are short. In the Philippines there is
inequality but less extreme. In Seram the cerata are short, equal in length but
not so reduced as in Bornean specimens.
Geographical range. N.E. Himalaya, Hong Kong, Burma, Sumatra, Borneo,
Java, Philippines, Sulawesi, Seram.
Habitat preference. An old specimen is from Tenom in the lowlands and a
more recent one is from lowland forest at Danum Valley Field Centre, both in
Sabah. The species would appear to be uncommon.
