This was at the tip of a leaf of a small Eucalyptus tree. A nice surprise almost right outside my office.

Moved from Acrocera.

This keyes to A. melanderi in Sabrosky(1)(1948)...the relevant couplet sequence details appear in my comment under Alice's post below:

   

And like Alice's post, the projecting terminalia in your 3rd image indicate this is a female.

Also...in accord with your post here...Sabrosky(1) in his discussion of A. steyskali (= melanderi), remarked that:

"In the females, the second tergite may be entirely black, and the yellow spots on tergite III greatly reduced in size."

 
thanks
again!

Nice find, Joyce!
This...and most Acroceridae specimens with good profile images showing: mouthparts ("long and conspicuous" vs. "small and/or imperceptible"); antennal position; and eye vestiture...can be taken to genus fairly easily using the "photo key" I assembled on the family "Info Page".

This one is in the type genus, Acrocera. Getting to species is a bit more work...will try when I have a bit more time.

(PS: Long time, no see...hope all's well with you :-)

Moved from Small-headed Flies.

 
thanks Aaron
Somehow I failed to notice the nice key on the Info page. Very helpful for next time!

Yes, all is well...
