At first be careful about area of setulae, you told me:
"The raised ocellar triangle includes a narrow, yellow border. The yellow border has six or seven setulae on each side."
So, seems it shows those are in outer margin of ocellar triangle, Please look at your sample more carefully, setulae are like the first one pic that I showed you? (They are related to Thaumatomyia sp.) In first pic, the setulae are inner margin of triangle and also if you see, setula are all over margin of, not just six or seven setulae!!!!
Anyway, I wrote for you other characters in the key for arriving to Chloropsina genus! :)

- Ocellar triangle with 1 or more rows of setulae on lateral margins. *
- Ocellar triangle without setulae on lateral margins.

- Scutum yellow with more or less developed black or red stripes; rarely entirely dark, then with scutellum flattened and apical scutellar setae approximated. *
- Scutum entirely black.

- Scutellum flattened and with approximated apical setae.
- Scutellum not flattened, apical setae not approximated. Chloropsina

Please tell me your reason! :)
