DISTRIBUTION:

Salassa albocirculata (forewing length: males: 73-77mm; females: 79 mm) flies in
southern Vietnam:
Kon Tum Province: Dak Nong;
Lam Dong Province: Bidoup, 1500 m; Lam Dong Province: Kreis Lam Ha, Gemeinde Bhu Son, Regenwald, 1320 m;
Lam Dong Province: 19 km von Di Linh nach Phan Thien, Regenwald, 1207 m.

The forewing ground colour is bright orange brown on the dorsal surface. The apex is only very slightly produced and the outer margin is relatively straight and only slightly oblique. The forewing ocelli, outlined in black, are large, transparent with a greenish cast and house a small black region pointing toward the apex. The dentate postmedian line is an orangey-brown that curves slightly toward the body as it nears the costa. There is a generous suffusion of grey scaling in the subterminal area.

On the hindwing, the white am and pm lines merge to form a complete loop around the relatively small, bean-shaped ocellus which is completely outlined in white. There is a prominent black band high above the ocellus, inside the white arc. There is a greenish hyaline c-shaped (right hindwing) marking, comprising about one-third of the area of the otherwise black ocellus.

This moth seems very similar to Salassa megastica, which also flies in southern Vietam.

The ventral surface is maroon with a generous suffusion of white scaling in the basal and median areas, and an even heavier suffusion of white in the subterminal area. The am and pm lines are a series of greyish white line segments, with the pm line inwardly bordered by a diffuse band of brownish-grey scales. The marginal areas of all wings are reddish brown.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

Moths are on the wing in March-April, June-July-August and possibly in other months.

Larval hosts are unknown.
