Mnesictena daiclesalis is a moth in the family Crambidae.

The forewings are ferruginous brown, irrorated (sprinkled) with dark grey.

The inner margin is rather broadly suffused with ochreous orange from the base to three-fourths and there is a narrow ochreous-orange streak along the costa from the base to three-fourths, enclosing a very slender snow-white costal streak from one-fourth to two-thirds.

The lines are thick, cloudy, dark grey and very indistinctly defined.

The hindwings are light ochreous yellowish with a dark-grey dot in the centre of the disc and partial indications of a slender greyish line at two-thirds.
