Really poor images, but it looks to me like it has been stylopidized.

Female found lodged on the abdomen of a Polistes individual
Below Shelley Beach Rd (vicinity of 81 Shelley Beach Rd), St Marys Bay, Auckland 1011. Inside syconia on Ficus rubiginosa.
Very tiny.
I saw that on "Scolymus Maculatusl plant" .
This is Eutrichosoma mirabile, a parasitoid of seed-feeding weevil larvae. I'm uploading this as a reference because I'm hoping to get a better sense of their distribution from more observations. Sunflowers and acacia are among their known host plants.
Parasite within abdomen.
Brasixenos mesoamericanus Quintos-Andrade & Valenzuela-González, 2023
Parasite of Polybia plebeja
Black wasp with a white band on the abdomen.
Fourth year of nesting in my retired newspaper box, first year they started two nests. Wonder if they will converge...

Stylopized (see abdomen!)
Per @humanbyweight's ID. Visible on lower left with zooming.
this paper wasp is infested with at least one twisted wing insect on its abdomen
In recently deceased male P. fuscatus

The parasite near the end of the paper wasp abdomen.
Paper wasp obs. is at https://www.inaturalist.org/observations/17950191
four male pupae are visible partially emerged from the wasp's abdomen; likely X. peckii, which is a parasite of the paper wasp Polistes fuscatus
Stylopid pupa. IDing as Xenos because the host is a wasp in genus Polistes. The wasp was found lethargic in an apartment entryway with four stylopid pupae in its abdomen. Wasp was captured and placed in a container with sugar water and a folded paper towel. 3 of 4 adult males emerged before the wasp died. 2 of those were found dead in the sugar water. The third was found dead in the paper towel. Will add observations of one of the dead adult males.
Reared from Polistes sp.
Having never seen one before, I've been fascinated by Strepsitera in recent days and been checking every Polistes wasp just in case - then a male flew in to the house and landed on the table in front of me! I fear that its rear abdomen was slightly damaged in some photos as it was under a glass.
@gung Hi Daniel, is there enough detail here to determine the family, or further? With many thanks

I think that's a strepsipteran sticking out from the abdomen of the lacewing. I didn't notice it when I took the picture or else I would have tried to get a better close-up.
Adult male stylopid in genus Xenos. Emerged from a wasp in genus Polistes (see separate observations for the wasp and one of the pupae) which was found lethargic in apartment building entryway. Found dead in the paper towel in the wasp's container, so no live photos. One of three males that emerged and died before I found them, unfortunately. Last two photos show the host wasp and one of the empty pupae.
