Pseudatrichia
Osten Sacken, 1877
Pseudatrichia is a of small flies in the Scenopinidae (window flies), established by Osten Sacken in 1877. These insects belong to the tribe Metatrichiini within the Scenopininae. Members of this genus are poorly studied, with limited biological and ecological data available in scientific literature. The genus is distinguished from related primarily by morphological characteristics of the wing venation and male genitalia.

Identification
Separation from the related Metatrichia relies on wing venation patterns and structural details of the male terminalia; specific diagnostic characters require microscopic examination. The genus can be distinguished from other Scenopinidae by features of the capsule and antennal structure, though precise identification to level generally requires taxonomic knowledge and reference to original descriptions.
Distribution
Records of this are sparse; occurrence data suggest a distribution in the Nearctic region based on original descriptions, though precise range boundaries remain undefined due to limited collecting effort and taxonomic study.
