Members are characterized by small heads, glabrous eyes, and long palpi where the second segment is laterally compressed.

The ninth ventral segment, or the vinculum, is narrow with a rounded saccus, and the juxta is shield-shaped with a deep notch on its upper edge.

If the hindwing underside's marginal area is divided into distinct pale spots, the species is identified as Erikssonia cooksoni.

In the case of Erikssonia alaponoxa, the forewing is elongated with a straight margin that is angled at M2 region, displaying reddish-orange upper side and blackened wing base coloration.

In contrast, Erikssonia acraeina exhibits a forewing that is not elongated, with margin that is neither straight nor angled at the M2 region.
