Strongylophthalmyiidae
Hardwood Flies
Strongylophthalmyiidae is a small family of slender, long-legged flies containing approximately 80 species across two genera: the monotypic Southeast Asian genus Nartshukia and the cosmopolitan Strongylophthalmyia. The family's phylogenetic relationships remain unresolved, having been variously classified with Psilidae or Tanypezidae. The majority of species occur in the Oriental and Australasian regions, with limited representation in the Nearctic and Palearctic.
