Froggattimyia fergusoni Malloch

Froggattimyia fergusoni Malloch, 1934:4–5 Type. Holotype male in ANIC, Wyalkatchem, WA Also very similar to F. wentworthi, but the male with strongly differentiated reclinate upper orbital bristles; parafacial often with setulae more or less confined to dorsal half. Terminalia with syntergosternite 6–8 rather longer, with less steeply sloping posterior margin (but not as marked as in the next species, F. vicina sp. nov.); surstyli in posterior view more or less straight or incurved.

Females associated with identified males are barely separable from those of wentworthi. The setulosity of the parafacial is rather reduced in some specimens, but the difference is hardly striking. However, with more and better identified specimens, the blue-grey pollinosity of the tergites (and especially tergite 5) may prove useful to separate this species from wentworthi, but not from other Froggattimyia spp.

Distribution. WA and SA; one doubtful record from NSW.

Biology. All but two specimens were reared from larvae of unidentified species of pergid sawfly.

Notes. With additional material, Malloch’s characters for differentiating this species no longer hold. In particular, his type specimen has an abnormally broad parafacial and unusually narrow median dark stripe on the abdomen. However, I am fairly sure that this is a good species and that it includes the holotype.
