Sypna fenella Swinhoe, 1902, Ann. Mag. nat. Hist. (7), 10: 496.

Hypersypnoides fenella Swinhoe; Holloway, 1976: 31.

Diagnosis

The species comes in two forms: with and without arrays of white spots delineating the forewing stigmata, distal margin and the subbasal, antemedial and postmedial fasciae. Constant features distinguishing fenella from congeners are: a wedge of paler brown at one third from the forewing costa between the margin and the postmedial; extensive and continuous dull pale ochreous marginal zone over the anterior half of the hindwing (deeper than in Sypna rholatinum().

Geographical range
