Psammathodoxa cochlidioides

Distinguished from similar Erebidae by the combination of small size (25 mm wingspan), creamy brown forewings with darker shading, and the distinctive pattern of approximately fourteen wavy transverse lines creating an irrorated effect. The straight pale line from apex to inner margin with brown edging is a key diagnostic feature. Similar species in related genera lack this specific line pattern and irrorated appearance.

Wingspan approximately 25 mm. Forewings creamy brown with darker shading except along the costa and basal area. Wing crossed by about fourteen irregularly waved light transverse lines, creating an irrorated (sprinkled) appearance. A straight pale line with brown inner edge runs from the apex to the middle of the inner margin. Hindwings uniformly brown.
