Diagnosis.
This is a similar species to trapezium, with similar sexual dimorphism, but smaller, darker
brown, with the forewing reniform more of a narrow bar. The antemedial and
postmedial form a similar, distally rounded trapezium, but the lines have pale
interior and dark exterior components. The submarginal of the forewing is
single, pale, curved over the posterior two thirds, and then zig-zag subcostally
where it encloses basally two blackish marks.
Geographical
range. Indian Subregion to China, Taiwan, Thailand (VK), Burma, Sumatra,
Borneo. It was noted in Micronesia (W. Carolines: Palau) by Fukushima (1947).
Habitat
preference. Records consist of only four female specimens, taken in Brunei
in recent surveys: one from disturbed lowland forest at Labi (30-60m); three
from dry heath forest on sand at Telisai (15m).
Biology.
The larva was described by Gardner (1941, 1947). Unlike congeners, A8 lacks any
tumidity. The general colour is dark brown. The head is lined longitudinally
with black and paler brown lines, and has a broad yellow band laterally. Black
delineation continues onto the thorax. The abdomen has the dorsal surface
densely speckled black, with larger black spots on A1 and A8, but the setae are
based on white spots. The pattern is more linear laterally, with the numerous
lines dark brown. There is a pale line below the spiracles, and the ventral
surface is speckled black and brown. The true legs are red; the spiracles are
pale with black rims.
The pupa
lacks a bloom (Gardner, 1947).
Host
plants recorded (Gardner; Miyata, 1983; Robinson et
al.,
2001) are Terminalia
(Combretaceae),
Shorea
(Dipterocarpaceae),
Syzygium
(Myrtaceae)
and Pinus (Pinaceae).
The
adult is recorded as a fruit-piercer in China (Wu, 1981).
