Chris,

The other one is possibly a sp. of Ocnaea. That is, it looks like Nearctic members of this genus (I am hesitant, however, to extend my very limited knowledge of this group to the Neotropical fauna...). There is a key that is being printed "as we speak" -- volume 1 of the "Manual of Central American Diptera" is in press and "at the bindery." This will cover the families of Nematocera to the Empidoids, and will include the Acroceridae of course. Same coverage (and same publisher) as the super "Manual of Nearctic Diptera" which appeared in the early 1980's. Volume 2 should appear within the year (and will have a massive and fantastic chapter on Tachinidae by Monty Wood). Fans of Neotropical Diptera are eagerly awaiting these volumes!!
