Not the same specimen

One is a male and the other a female, which means that they are not the same specimen. You could link them for reference but not as same specimen.

okay..

I made sure to clearly state that one was a male and the other a female?

I never meant to imply it was the same specimen..

So, I should post a new ID Request for the female, or how does this work?

Unlink them

You just unlink them and then you can link them, just for reference, using the [thumb#]. More information on the markup page.
It is such a nice series that it is worth linking them, but without confusion.
There was no page for Albibarbefferia, so I created it and moved them there (nice addition). Next time you can move your own images to the right page after they have been ID'ed.

Done and done!

Thank you for the help, and for creating a page.

Efferia

Beautiful Efferid shots. Male and female. Remember that Texas has an incredible list of Efferia species. And the giant genus has been divided into several new genera but it is not accepted by all the North American Asilid scientists. I put them in their new genera on my robber site. See the Texas list here:

This is very likely Albibarbefferia albibarbis so you are correct in saying it resembles it. The number of silvery segments separates many of the males. And the leg colors. Unfortunately a major separation is determined by a wing vein character. Texas has six Albibarbs. This species loves sandy water areas and shorelines.

new image

I added a another photograph which shows the wings at a better angle, perhaps not well enough though?

… Seth Patterson, 5 July, 2005 - 9:18pm

thank you

Very insightful comments, and website. I'll go back over my shots and see if I have any with wings clearly visible, but I'm afraid I don't. I'll keep this in mind for the future though.

I really appreciate the help!
