Aroa

Diagnosis. The species occurs in two forms. One has a white ground, the other a
pale dull yellow ground. The dark brown markings are similar to those of barlowi,
but with more basal shading on the forewing and a broader dark brown costal
margin to the hindwing. The species is also much larger, with a more acute
forewing apex.
Taxonomic notes. The species was originally described in Aroa because of its
superficial resemblance to Aroa cometaris Butler from the Solomons. The
male genitalia and venation are typical of Rhypotoses, the valves being
of the quadrilateral type, though lacking a lobe at the saccular angle. A.
cometaris is also misplaced in Aroa, being an orgyiine of the Orgyia
generic complex (See Orgyiini)
Geographical range. Borneo.
Habitat preference. All records are from G. Kinabalu over an altitude
range of 1200m to 1660m.
Biology. The species is day-flying.
