Nausigaster curvinervis
Curran, 1941
Nausigaster curvinervis is a of hoverfly in the Syrphidae, described by Charles Howard Curran in 1941. It belongs to the tribe Merodontini, a group of small to medium-sized hoverflies often associated with bulb-forming plants. The Nausigaster is characterized by distinctive wing venation patterns. Information on the and of this species is limited due to its rarity and lack of recent observations.

Identification
The specific epithet 'curvinervis' refers to curved wing , a diagnostic feature distinguishing this . Within the Nausigaster, identification relies on subtle differences in wing venation and body proportions. Merodontini hoverflies generally have a reduced or modified spurious vein in the wing, a trait useful for distinguishing them from other syrphid . Detailed examination of male genitalia is often required for definitive species-level identification in this genus.
Distribution
The was described from material collected in North America, but precise locality data and current range boundaries remain poorly documented. No verified occurrence records are available in major biodiversity databases such as GBIF or iNaturalist.

Taxonomic history
The was established by Canadian dipterist C.H. Curran in 1941 based on limited material. The Nausigaster currently contains approximately 15 described species, primarily distributed in the Holarctic region. No taxonomic revisions have focused on this species since its original description.
Data deficiency
This has zero observations in iNaturalist and no occurrence records in GBIF as of 2024, indicating either extreme rarity, cryptic habits, or possible synonymy with another species pending modern taxonomic revision.
