Diagnosis and taxonomic note.
This and the next three species may form a group that, with allied species elsewhere in the region, may merit generic status. The build is more delicate, the wings more elongate than in typical Barsine, but the forewing fasciation is somewhat similar to that of B. cruciata (see "Barsine" pallinflexa sp. n.), with angling and central fusion of the antemedial and subbasal forming a letter ‘X’. The submarginal has three more prominent spots, one near the costa (often obscure) and two on either side of the centre of the wing; these are also emphasised in some of the more typical Barsine species. In the male genitalia, the valves lack a central costal process, but may have the two more distal ones or have the valve apex entire. The aedeagus vesica has only smallish coarse spines and may also have additional longer ones (porphyrea Snellen). In porphyrea and sullia Swinhoe the apex of the aedeagus or anellus where it fuses has patches of spines on each side. The female genitalia of porphyrea have two scobinate signa in the bursa.

“B” exclusa and “B“ porphyrea Snellen are almost as large as cruciata. They differ slightly in facies, the latter having paler patches on the forewing rather yellow, rather than brick red, though yellowish forms of exclusa occur. In exclusa the inner boundary of the patch of ground colour containing the discal spot is concave, whereas it is straight in porphyrea. The postmedial, antemedial and subbasal fasciae all meet the dorsum more or less in parallel in exclusa (the ‘X’ is rather distorted), but in a more zig-zag fashion in porphyrea. The Andamans subspecies, trivittata Moore, has the valves of the male genitalia with rounded, rather than acute, apices.

Geographical range. Sundaland; Andamans (ssp. trivittata).

Habitat preference. This is an uncommon species of lowland forest, including secondary forest.
