Description of adults: Examined: Black-and-white drawing of holotype in original description, complements following Amsel, 1961. Wing expanse: 12 mm. Vestiture of hair-like scales on the head yellowish; labial palpi yellowish; antennae 1/2 () of forewing length, yellowish; forewings blackish with weak violet shimmer and yellowish-white markings: A small roundish costal spot at 4/5, a small triangular spot basally of the tornus, emanating into the fringe; an elongate, narrow spot at the inner margin at 1/3, reaching across half of the wing width; a very small costal spot at 1/3; fringe consisting of two rows of scales, the inner row just like the ground colour, the outer row pale yellowish; hindwings and fringe blackish; abdomen blackish.

Distribution:

The taxon is only known from the single type specimen from Baden-Württemberg. It is not included in Fauna Europaea (Karsholt & Nieukerken 2010).

In the original description, Amsel (1961) compares his new taxon I. brigantinella with Incurvaria oehlmanniella (Hübner, 1796), Lampronia intermediella (Heinemann, 1870), a taxon of uncertain identity (see Karsholt & Nieukerken 2010), and Lampronia capitella (Clerck, 1759). Following Amsel, the first two species are easily distinguished by the brown colour of the fringe, being whitish outwards in I. brigantinella. L. capitella is distinctly larger and lighter in ground colour. No comparison, however, is made in that paper with Incurvaria praelatella ([Denis & Schiffermüller], 1775), which has a distinct white fringe. I. brigantinella therefore could perhaps be a darkened form of that species with somewhat reduced inner fascia. In TLMF, a series of specimens from the Bodensee area is deposited under the name Lampronia flavimitrella (Hübner, [1817]), which are quite dark in colour (Huemer in litt.). So far, we have not been able to investigate these specimes, which hopefully might clarify the problem. L. flavimitrella also is a species with somewhat whitish, although less well pronounced white fringe, but normally much lighter in ground colour.
