Cossedia acolutha

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.
