Notes on Delias ribbei :

Very similar to Delias enniana, which can also be found on Mysool Island in one of its forms.

The large distance between the subspecies, suggested that the species should be found also on the intervening islands. The fact that it has only recently been confirmed to be found on Obi (August 2002) substantiated this.

Male: Upperside white. Fore wing with grey-black outer marginal border bearing five large white submarginal spots, the anterior three larger and partly connected with the white area by white dusting. Hind wing with outer margin narrowly grey-black.

Underside of fore wing white with broad grey-black apical half, extending to costal two-thirds, end of cell and vein 4, and at the margin just below vein 2. Submarginal spots more strongly marked than above, the two anterior ones yellow. A short white costal bar beyond the cell. Hind wing with a grey-black marginal border about 7mm. broad, bearing six yellow submarginal spots which are narrow and are separated by the veins. Proximal area of hind wing yellow.

Female: Fore wing with broad grey-black anterior area and white proximal area. Costa and base of cell broadly grey-black, as well as the outer margin narrowing to the tornus. The edge of this area is rounded, passing through the upper end of cell and the base of cellule 3. Submarginal spots larger than in the male. Hind wing white dusted with grey-black; and ill-defined broad grey-black marginal border bearing five white submarginal spots of which the two anterior ones are well-developed and the two posterior ones rather small.

Underside similar to the upper, the grey-black colour with a violet gloss. The cell of the fore wing, inner third of hind wing and submarginal spots of hind wing of a beautiful orange-yellow. the remainder of the fore wing proximal area, and the costa of the hind wing white. Submarginal spots of both wings much larger than above, those of the hind wing slightly connected distally. The grey-black area of hind wing enters the cell.
