22-23mm. This is much larger than the other two species and somewhat larger than
indica Moore. The forewings are generally much darker, with the dorsal
markings distinct, whitened, the main 'step' perpendicular to the dorsum. In the
male genitalia the valve is somewhat broader, the apical finger-like
process shorter and broader than in indica. The vesica of the aedeagus is
broader but the group of spines is distal as in indica. The ventral part
of the triangular juxta is diagnostically strongly excavate. An externally
similar species flies in Sulawesi (slide 14063) but this differs in male
genitalia (juxta not excavate; spiny zone of vesica more extensive and more
basal).
