I’m pretty sure this is Tachysphex (Genus), but there are similar in Tachytes (Genus). I’ll verify it as Tribe Larrini for you as it contains both genera.

Larrini (Tribe)

I agree with @michael.batley, this looks like Williamsita (Genus). See examples of similar below.

Head, body & legs (together with spur number and placement) in addition to wing venatian look like this could be one of the Mud-nesting Spider Wasps in Auplopus (Genus) but I’d need someone with more experience to confirm.

Pompilidae (family)
