Eupterote multiarcuata Holloway, 1976: 54.
(.73 natural size)
Diagnosis. The wings are more evenly fasciate than in the next species, the
fasciae rufous brown rather than greyish brown.
Taxonomic notes. The species is close to the Javan amaena Walker but is larger,
more strongly fasciated but with the postmedial broken rather than entire
(though amaena is variable in this respect). The aedeagus vesica is heavily
scobinate in multiarcuata but unadorned in amaena. Both species may be in turn
allied to mollifera Walker from Sri Lanka and S. India.
Geographical range. Borneo, Sumatra, Peninsular Malaysia.
Habitat preference. The species is rare in lowland forest habitats.
Biology. The larva of amaena was illustrated (but see next species) by Horsfield
& Moore (1858-9). It is shown as dark brown with longitudinal white bands
dorsolaterally (broad) and below the spiracles (narrow). The dense secondary
setae are shorter than the body diameter. A preserved, fully grown specimen in
the BMNH appears less striped, more variegated dorsally, each segment with a
central, dorsal black patch, almost circular but for a pair of setal tufts that
indent the anterior margin laterally. Most setae are in this tuft, in a lateral
one below it and in ones more ventrally, displaced somewhat obliquely to the
posterior, i.e. the setae are most dense in a ring on each segment. The head is
paler brown with dark markings. Pupation is in a rough silken cocoon.
The host-plants recorded were Vitex (Verbenaceae), Piper (Piperaceae),
Erythrina (Leguminosae) and Dioscorea (Dioscoreaceae).
