Ocyptamus genus of over 300 species of hoverfly mostly found in the Neotropical region. It is likely that many of these species will be discovered to be synonyms though many others await description. Also there is some evidence the genus is not monophyletic and is paraphyletic with regard to Eosalpingogaster and Toxomerus
