The wingspan is 4.3–5.9 mm for males and 4.3–5.2 mm for females. Two-thirds of the forewings is dark fuscous with purplish reflections, there is a shining silver to pale golden fascia at 2/3. The apex of the wing is dark fuscous without reflections. The hindwings are grey.[1]

Mine

The larvae feed on Tristaniopsis collina. They mine the leaves of their host plant. The mine starts as a very long narrow gallery either filled with greenish frass or with black linear frass. It broadens rather abruptly into a gallery with a central line of black frass. The exit-hole is located on the upperside and has the form of a semicircular slit. Pupation takes place in a reddish-brown cocoon.

Etymology

The specific name is derived from the Latin brevis (meaning short) and palpus (meaning the sensitive palm of the hand) and refers to the reduced, 2-segmented labial palpi of the adult male.

gollark: The freedns subdomains are just ones which people opted into having subdomains on.
gollark: And have "further information" links which lead into some complex maze.
gollark: Anyway, when you scroll down it should talk about the Organization's expertise in leveraging operational synergies or something.
