Diagnosis and taxonomic note.
The original descriptions of the taxa brought into synonymy were each based on one female of what appears to be a single variable species, as no differences in the male genitalia could be detected except variation in the number of spines in both clusters in the aedeagus vesica across the range of forms, though the two dissected males of the third form mentioned below both had lower numbers of spines (Fig 283). The forewings are rich brown with a white lining to the costa. They are variegated paler in some forms in a similar manner to the greyer sabulosa and metaphaea. There is a more strongly zig-zag postmedial than in sabulosa, sometimes broadly delineated, sometimes rather crenate. The punctate submarginal has a white highlight on the distal side of each dark dot, though this is also variable in development. The forewing varies from a uniform dark brown (albimargo) through a more variegated rufous brown (vulpina) to an even more strongly variegated rufous and purplish brown form; the white submarginal dots are particularly strong in the last, which is more readily separated from the other two where more intermediates occur. The status and localisation of this third form require further study. The species identified by Kobes as vulpina is indeed a Xenochroa, and the specimen illustrated (Plate IV: 140, as moira in the legend) has none of the above diagnostic features.

Geographical range. Borneo.

Habitat preference. Material of the first two forms mentioned above has been taken between 1000m and 2600m, the species being common between 1500m and 2000m. The third form was taken only on the limestone G. Api during the Mulu survey, at 250m (1), 900m (4) and 1200m (1), though a further specimen was taken at 1618m on Bukit Retak in Brunei.
