Coleotechnites nigritus is a moth of the Gelechiidae family. It is found in North America, where it has been recorded from Florida, Kentucky and New Hampshire. The wingspan is about 11 mm. The forewings are silvery white, thickly overlaid with black and dark fuscous scales. There are six deep black spots of raised scales in two rows, one above, the other below the fold. At apical fourth is a very narrow, irregular, V-shaped, silvery white fascia, with the angle pointed toward the tip of the wing, and farther out towards the apex is a very indistinct thin row of white scales, parallel with the costal edge and meeting a similar line parallel to the dorsal edge just before the apex. The hindwings are nearly black, with metallic a luster.
