Hypenodes humidalis, the marsh oblique-barred, is a moth in the family Erebidae.

The forewing is whitish ochreous, irrorated (sprinkled) irregularly with brown and dark fuscous.

The subterminal line is straight, whitish, ill-defined and preceded by fuscous suffusion, running to the apex.

[4] The larvae possibly feed on Juncus and/or Carex species.

Pupation takes place at the stem of the host plant.
