Hi all!
This is acutely embarrasing - I can sex Drosophila without thinking (or a lens)... But what sex are these flies?
Are they both male, or is the right on male, and the left one female?
Thanks!

Both male - the curved tip of the aedeagus is just visible in both specimens.

The two are males.

Note small subconical cercus and, below it, flat bristled lamellae of oviscapt, arising from near the median line.
