Phytoliriomyza pittosporophylli

Phytoliriomyza pittosporophylli and the similar-looking P. pittosporocaulis both have a pale frons, a lunule approximately in the form of a semicircle, reclinate orbital setulae, a black scutellum, pale halteres, and dorso-central bristles in a 3+1 arrangement.^[3][4] It can be distinguished from P. pittosporocaulis by the third antennal segment being entirely black.^[3][4]

The larva has 8-10 bulbs in each posterior spiracle; this differs from the 4-6 bulbs of P. pittosporocaulis.^[5]

Full descriptions of the adult and larva (and the gall produced by the latter) were given by Hering.^[5]

Larvae of this species form circular leaf galls on sweet pittosporum (Pittosporum undulatum).^[3][4] Galls are usually near the midrib but can also occur elsewhere in the leaf.^[3]
