Froggattimyia nicholsoni Malloch

Froggattimyia nicholsoni Malloch, 1934:5.

Type. Holotype male in ANIC, Lindfield, NSW (published as “Sydney”).

Extremely similar to F. wentworthi, and possibly only a variant of that species; male differing principally in having the reclinate upper orbital bristles moderately well differentiated—distinctly more so than is usual in wentworthi, but less than in F. fergusoni Malloch and F. vicina sp. nov. Also, abdominal dorsum with grey, rather than golden pollen (but this sometimes true of wentworthi). Terminalia within the range of wentworthi in the shapes of syntergosternite 6–8, cerci and surstyli.

The female has not been distinguished, and is presumably identical with that of wentworthi.

Distribution. NSW, Vic., WA; no doubt in SA as well.

Biology. Bred from “sawfly larvae”, some identified as Perga species.

Notes. I am strongly tempted to synonymize this species with F. wentworthi, but have taken a more cautious path following Malloch who separated the two species albeit on different grounds. All but the type were reared from sawfly larvae or cocoon masses, including Perga sp. and Pergagrapta turneri Bens.
