Hello all!

Looks like O. antiphates from here, could be O. dimidiatus though. I personally think both species are the same, but I haven't gone around to conclude on that... well, if you can see a clear dark stripe on the face it is O. dimidiatus... if wholly pale face, O. antiphates. The females have a more clear cut darkening of the wing (basal 1/2 or 2/3 dark, hyaline apex) while the males should have a mostly dark wing (paler apex).

O. fascipennis flies are more delicate-looking (longer narrower abdomens) and with a distinct dark triangular marking on the wing.

Sorry for the delay in joining the group!!

Cheers,
Gil

Hi Gil, Welcome to BugGuid

Hi Gil,

Welcome to BugGuide! It's wonderful to have you and your expertise here. Hope the Amazon is going well :^) (searching for a postdoc myself at the moment)

Welcome to Bugguide!

Hi Gil,

Glad to see you here. I am sure you will a big help.

A few things for you to look at first.

Could you confirm that these specimens are O.antiphates? I keyed my similar but darker specimens I collected to that species using Thompson's unpublished key so I had them placed there.

Could you also confirm that this specimen is O. cylindricus?
http://bugguide.net/node/view/87148/bgpage

I have been a very busy Asilid down in the Everglades and I've caught a ton of Ocyptamus and one Hybobathus lineatus that I was stoked to catch.

I will also post some pictures of what I believe to be Ocyptamus cylindricus that I caught from Florida. What should we be looking for to indentify that species? They looked exactly like this specimen here http://bugguide.net/node/view/158699/bgpage that you said was cylindricus but their abdominal color has faded after death to purple.

Kind regards,
Kevin Moran

Hi Kevin!

Page 882666 is all O. antiphates, no problem... Yellow is pretty bright on some of them though (photo editing perhaps?)

On page 87148, I would probably still bet on O. cylindricus (even though the different hue is not visible in that particular photo). From the current records that I have, it can't be anything else really...

Most likely they will be O. cylindricus, Kevin. But then again, The Ocyptamus sensu stricto could use a revision so we could straighten out all the species (revision to be announced at some point ;)).

Keep 'em coming!

Cheers,
Gil

Most likely. I am sending a pair of these I collected in Florida to Jeff Skevington for closer examination and I will let you know if anything changes.

Interesting.

Might be a syrphid, but wing veins seem odd. Please move your post to Flies for expert attention. I think there's a variety of syrphids special to Florida.

… Ron Hemberger, 20 October, 2009 - 8:20pm

Ocyptamus?

Compare Ocyptamus fascipennis. Could be something in that genus based on shape and wing bands and what little I can see of wing veins.
