Holocacista varii is a moth of the family Heliozelidae.

The forewings are grey brown with some bronze lustre and with a silver-white patterning, an oblique fascia at one-fourth, hardly narrower at the costa.

There is a slightly triangular dorsal spot at one-half, not reaching the middle of the wing.

The mine starts towards a vein and then follows the vein as a narrow gallery, eventually rather suddenly enlarging into a more or less triangular or elongate blotch, usually after the mine makes a turn of 180°.

The larva probably descends with its cocoon into leaf litter before pupation.
