fIavistriga Warren comb. n.
Epiplema flavistriga Warren,
1901, Novit. zool., 8: 21.
Epiplema flavistriga Warren;
Holloway, 1976: 87.
Diagnosis. This is a distinctively large and pale species with the dark brown band
of the postmedial broad and broken into blocks by pale lines along the veins
(including the position of CuP). The discal spots are strong and the hindwing
postmedial is tinged yellowish (faded in the only Bornean specimen).
Taxonomic note. D. secutaria Walker comb. n. (Sumatra) is related but is smaller
and grey in facies, similarly but less strongly marked with black and with the
fan of modified scales on the valve half the width of that of flavistriga. The
type (in UM Oxford) is male, though stated to be female in the original
description.
Geographical range. N.E. Himalaya, W. China, Taiwan, Japan, Borneo.
Habitat preference. A single female has been taken in Borneo, at 1760m on
G. Kinabalu.
Biology. The larva of flavistriga or a close relative has been studied in
Taiwan (Chen, 1997; S.-H. Yen, in litt.). It is stout, slightly broader
posteriorly, a translucent, glistening pale brown, with rows of black spots: a
dorsal pair, a subdorsal row on each side displaced slightly posteriorly to the
dorsal ones, and a lateral row just above the spiracles.
The host-plant recorded was Daphniphyllum (Daphniphyllaceae).
