One of the insects (top) is Idioscopus nitidulus (Walker) – sent by the same person from mango, from Indonesia, previously. See message post 6414:

.

The other (below) is a psyllid. This from the Australian Museum:

Look at the wing veins, legs, head, abdomen….

With this reduced wing ventation and small head with laterally prominent eyes its a psylloid. See Insects of Australia p.432 (wing venation of related Trioza, p.450). On that page, Leptynoptera sulfurea (Triozidae)
is cited as ‘widepread in the Pacific’ on Calophyllym.

Googling that name gives its taxonomy:

The Calophyllum-feeding triozid genus Leptynoptera (Hemiptera: Psylloidea) (

1992)
