Diagnosis. See the generic description and the
account of Euxena albiguttata on (Euxena
Warren).
Geographical range. Indian Subregion to Sundaland.
Habitat preference. The two specimens taken in recent surveys
were from alluvial forest at the foot and in primary forest on the lower slopes
(250m) of the limestone G. Api near the Melinau Gorge.
Biology. The larva was described by Bell (MS). The
head is squarish, the vertices conical but not strongly bifid. The body is
cylindrical, with A10 slightly conical dorsally. The skin is granular. The
colour is leaf green with a dark green dorsal line. There are oblique dark lines
coming from the dorsal line on each sgement anteriorly to the posterior margin
at the level of the spiracle. There is dark green suffusion in the angle between
these lines and dorsal line. The spiracles are sometimes surrounded by pink.
The larva adopts a stick-like resting posture, the markings
resembling the leaflets of the host-plant. Pupation is within a silken cocoon
spun amongst these leaflets.
The host-plants are shrubby species of Acacia (Leguminosae).
