Pigritia fidella
Pigritia fidella is a of concealer in the Stathmopodidae, a group characterized by larvae that construct distinctive portable cases from silk and plant material. The Pigritia contains small moths whose remains poorly documented. The specific epithet and taxonomic placement suggest affinities with other Pigritia species, though detailed studies are limited. are rarely encountered in field collections.
Identification
Separation from other Pigritia requires examination of genitalia ; external characters are insufficiently diagnostic. Distinguished from Stathmopoda by more slender wing shape and reduced hindwing venation. The 'cf.' designation indicates specimen identification based on morphological similarity rather than confirmed diagnostic features. Molecular data are unavailable for this species.
Appearance
are small with wingspans estimated at 6–10 mm based on congeneric . Forewings narrow, , with muted coloration in gray-brown tones. Hindwings narrower than forewings, with reduced venation typical of Stathmopodidae. , approximately two-thirds forewing length. Body slender, with giving a slightly iridescent sheen. Specific pattern elements remain undocumented.
Distribution
Published records are sparse. The has been reported from North America, with specific localities undocumented in available literature. Precise range boundaries remain unknown.

Taxonomic Uncertainty
The 'cf.' notation indicates this identification is provisional, based on comparison with described material of P. fidella rather than examination. The was described by Walsingham in 1882, but modern revisionary work on North American Pigritia is lacking.
