Trachycentra calamias is a moth of the family Tineidae described by Edward Meyrick in 1886.
It is found on the Cook Islands, Fiji, French Polynesia and Tonga.
There are faint indications of numerous small brownish-ochreous spots and two small tufts of raised black-tipped scales on the submedian fold before and beyond the middle.
There are also some blackish scales forming an obscure X-shaped mark in the disc beyond the middle.
[3] The larvae have been recorded feeding in the tops of coconut trees.
