Dichomeris thanatopsis is a moth in the family Gelechiidae. It was described by Oswald Bertram Lower in 1901. It is found in Australia, where it has been recorded from Queensland.[1]
The wingspan is about 15 mm. The forewings are whitish grey with some minute fuscous dots near the base beneath the costa, and above and beneath the fold. There is a dot on the fold before the middle, other discal dots are obsolete, but there is a dot on the tornus and a few fuscous scales before the termen. The hindwings are dark grey.[2]
