Thornburghiella is a of moth flies in the Psychodidae, established by Vaillant in 1982. It belongs to the tribe Pericomini and is characterized by specific morphological traits that distinguish it from related genera.

Identification
Thornburghiella can be distinguished from other Pericomini by genitalic characteristics, particularly male terminalia structure. Species-level identification requires examination of microscopic features of the hypopygium and wing venation patterns. The genus lacks the pronounced wing hair fringes seen in some related psychodid genera.
Distribution
Records indicate presence in the Nearctic region, with observations from the southwestern United States. The appears to have a restricted geographic range compared to more widespread psychodid genera.
Similar Taxa
- PericomaBoth belong to tribe Pericomini and share general body plan; Pericoma is more -rich and widely distributed, with different male genitalic architecture
- TelmatoscopusOverlaps in preference and wing venation; Telmatoscopus typically show distinct separation and antennal proportions

Taxonomic history
The was erected by French dipterist François Vaillant based on distinctive characters of Nearctic previously assigned to other genera. The type species designation and full species composition remain incompletely documented in published literature.
Collection rarity
With only 9 observations in iNaturalist and limited museum records, Thornburghiella represents one of the more poorly known psychodid in North America. This scarcity likely reflects genuine rarity, small body size, and specialized requirements rather than simply lack of collecting effort.
