9-10mm. This is the smallest and most lightly marked of the four species, strong
grey marks being restricted to the forewing apex and a darker browner zone at
the base of the costa where it is strongly curved. The yellow is as pale as in
proesei. The male genitalia are again uniform with those of preceding
species. A possible female taken in the same locality as the Kalimantan paratype
is illustrated: the forewings are more extensively grey.
