Remarks. Macquart (1848) described Erax rufitibia from two females from Brazil (Rio Negro) and southern Haiti. Later, Walker (1855) described E. fortis from a male collected from Santo Domingo and separated it from E. rufitibia largely based upon its hyaline wings. Curran (1953) recognized that Macquart 's type series consisted of two species and the difficulty of identifying females, especially based upon Macquart's description. He proposed that the name E. rufitibia be restricted to the Rio Negro specimen, leaving the Haitian specimen without a name. The latter was subsequently synonymized with E. fortis ( Martin 1970) .
