Alloclita xylodesma is a moth in the family Cosmopterigidae.

The forewings are dark fuscous, faintly purplish tinged.

There is a moderately broad ochreous-white transverse fascia before one-third, partially edged with black and then with brown suffusion, the posterior edge angulated below the middle, the black marginal dots above and below this indicating the stigmata.

A triangular ochreous-white spot is found on the costa at two-thirds, and an ochreous-white dot on the tornus, connected by a narrow brown fascia in which is a small black spot representing the second discal stigma.
