Last updated October 03, 2025

Ocyptamus is a large and diverse genus of over 200 species of hoverfly mostly found in the Neotropical region.^[1]^[2] It is likely that many of these species will be discovered to be synonyms though many others await description.

Classification

There is evidence that the genus is not monophyletic ^[3]^[4] and is paraphyletic with regard to Eosalpingogaster and Toxomerus , and some subgenera have been given full generic status ( Hybobathus , Pelecinobaccha , Orphnabaccha , and Pseudoscaeva ).^[5]
