Plocamosaris auritogata is a moth in the family Gelechiidae.

It was described by Thomas de Grey in 1911.

[1] It is found in Panama, French Guiana and Brazil.

The forewings are reddish chestnut, with a patch of reddish ochreous, slightly raised scales on either side of the fold at about one-fourth and a small dark chestnut spot at the end of the cell, as well as an elongate transverse dark chestnut shade, separated from the termen by a shining lilac marginal line, which is widened upward to the apex, where it is diffused and diluted inward over the wing-surface, at least as far as the upper angle of the cell.
