joshklostermann's Identifications

I was thinking subtribe Gastrosericina, but the AI was "pretty sure" it was in genus Miscophus, so I backed off to subfamily out of caution. (I will be pretty shocked if the AI was correct about Miscophus, but, in fairness, the AI's second candidate was Larropsis).

I never did see this wasp perch. It kept hovering over this small patch of ground, with dead vegetation over sandy soil.

This wasp was very small, although the fact that I never saw it land doesn't help me give an estimate.

The immediate vicinity had Tachytes pepticus (a male clearly patrolling for females), Hoplisoides nebulosus (female), and several Tachysphex terminatus complex individuals (females with burrows, one with prey) -- as well as a couple of ground-nesting bees.

The wasp clearly has basal two terga red with the remainder black, and some silver apically on the first four terga. Apex of abdomen very pointed; I can't tell if there are 6 or 7 terga (but I would guess 6).
