Diagnosis. The labial palps have the second segment dark brown, almost twice the length of the head. The third segment is half the length of the second, angled upwards. The forewing discal spot is large, with a faint greyish ring within its discal half; it is in contact with the postmedial, which is straight at the point of contact. The submarginal is closely associated with the pale band on the distal side of the postmedial but does not extend forwards beyond two-thirds. The dark brown marginal marks across the veins of the margin are domed, particularly the one nearest the tornus. The male genitalia have exterior processes to the valve consisting of a distal claw-like process with a subbasal lobe and a sharp basal angle, together with a broad and gentle, setose lobe basad adjacent to the valve margin. The aedeagus vesica has a long and narrow row of small spines. The female genitalia have a moderate, sclerotised, slender antrum to the ductus, which is short distal to this and joins the corpus bursae asymmetrically. The corpus bursae is ovate to pyriform, relatively narrow, with a subapical signum typical of the genus.
Geographical range. Old World tropics to Japan and east to Australia, Samoa, Tonga and Rapa I.
Habitat preference. Two of the three specimens taken in recent surveys are from coastal vegetation in Brunei. The third is from dipterocarp forest at the foot of G. Mulu (150m).
