Orphnabaccha is a of hoverflies (Syrphidae) in the tribe Syrphini, native to the Neotropical region. The genus was reinstated by Hull in 1949 and later redefined when molecular studies showed that the formerly broad genus Ocyptamus was not monophyletic, leading to the split of several distinct genera including Orphnabaccha.

Taxonomic history
Hull established Orphnabaccha in 1949, but it was long treated as a synonym of Ocyptamus. Molecular phylogenetic studies in the 2000s demonstrated that Ocyptamus was polyphyletic, leading to the resurrection of Orphnabaccha and other to reflect monophyletic lineages.
