Mus., 8: 255.
Cypa decolor Walker; Rothschild & Jordan, 1903: 298.
Diagnosis.
Males tend to be more variegated than females. The submarginal fascia on
the underside of the male forewing is irregular, with dark grey distally
and yellow grading into reddish brown basally: the hindwing submarginal is
also crenulate. In the female these markings are obscure in an evenly red
background. The species could be confused with S. terranea but this is
greener brown above; the fasciae on both wings below in both sexes are
straight, that of the forewing with pale grey on both sides though there
is a basal reddish brown triangular zone that takes up half the area of
the wings.
Geographical
range. Burma, Peninsular Malaysia, Borneo, Philippines, Ceram, New Guinea.
Habitat preference. The moth is perhaps more common in the lowlands but
has been taken at over 2000m on
G. Kinabalu.
