Pristaulacus (female)…
See reference here.

Lacks tooth projection
As per previous comment: Two species, P. flavicrurus and P. stigmaterus look almost alike and both are common in the East. Would need to see the upper surface of the hindcoxae and presence or absence of a forward-projecting tooth on the pronotum to tell which species.
