Trophocosta conchodes is a species of moth of the family Tortricidae.

The forewings are light ochreous-yellowish, with violet-silvery iridescence.

The basal patch has a rather oblique edge and a moderately broad rather oblique central fascia.

There is also a moderate fascia from three-fourths of the costa to the tornus and a narrow terminal fascia formed by yellow-ochreous suffusion.

It is indistinct and marked with small tufts of scales, some of which are sprinkled with blackish.
