This is the " imperialis Cooktownform " ofPart 1, closely resembling A. imperialis , but differing as follows:

Male. Head: frons relatively short ( Table 2 , "Cooktown form"); antennal segment ratio 3.1-3.8. Carina slightly, but distinctly, flatter in profile, less protruding, and therefore less clearly separated from epistome. Wing: bend ofM relatively closer to wing margin, index 0.6-0.9; upper calypter more than 50% dark, the external margin and associated fringe continuing brown or golden-brown to junction with lower member. Legs: hind tibia ( Fig. 24 ) with conspicuous ad fringe of close-set bristles of more or less uniform length and strength, about as long as the tibia is wide. Abdomen: T 3 lacking the usual pair of median marginal bristles. T 3 with lateral pale patches reduced, sometimes absent. Genital segments lacking the strong, almost spiny bristles present in othermembers of the group.

Female. Differing from imperialis in the M-bend index and calypter colouration; also, lateral pale patches on abdominal T 3 usually absent; antennal segment ratio 2.7-3.2.

Notes. The species was first recognised morphometrically in the male sex only (see Part 1, Fig. 7). Additional diagnostic attributes were later discovered, including the colouration of the calypters, which enabled identification of females. The list of specimens examined includes a number identified since the morphometric studies were made.
