Hirtodrosophila duncani
(Sturtevant, 1918)
A North American fruit fly in the Hirtodrosophila, distinguished by unusual male genitalia that complicated its taxonomic placement for decades. Molecular evidence now places it near the New World Sophophora clade. Like other members of its genus, it is associated with fungal substrates.
