Red and black antennae make this little jewel especially elegant.
Color seem to vary regardless of gender, since another female (viewed from side) is ivory white rather than creamy yellow like this one.
General habitus and oval tegulae suggest Pterocheilus at a broad sense, but of course, special mouthparts are not visible from this angle.

Correct.
The way the wings are folded longitudinally tells you that at the very least it is a vespid.
