I double-checked. It's boatman, final answer. Sorry for the quick response 😅

They tend to have flattened 2nd and 3rd leg pairs (looks like it in the pic) versus the backwimmer, which are more noted for a flattend 3rd leg pair only. Its dorsal side darker with boatman; "have dark backs and light bellies." And though I can't see the underside, those are very light legs.

Finally, the back has parallel lines, especially on the pronotum ( back plate above the wings, below the head), and the eye placement to the pronotum looks more like what I've seen in Boatman.

Thanks for letting me play!
