This micro is heavily worn, missing most of the scales on the head and thorax and almost all of the wing fringe, but remarkably, the FW pattern is quite intact. I found the original description of this species by Barnes & Busck in which they mention this species is distinguished from sexnotella by the white color connecting two white dorsal patches (i.e., on rear FW edge).
