. Body and legs yellow, abdominal segment X and posterior third of IX dark brown; antennal segment I white, II–IV pale with II and apex of III and IV variably weakly shaded, V pale with apex light brown, VI–VIII brown; fore wings and major setae pale, but median dorsal setal pair on IX brown. With the character states in the generic diagnosis; antennae 8-segmented, III–IV with sensorium simple. Ocellar setae III 2.0 as long as an ocellus (

Fig. 19
); mesosternal anterior margin with about 12 setae; tergite IX median dorsal setae stout, arising on posterior third of tergite close to posterior setae (
Fig. 20
), posterior pair I shorter than pair II; X with median split complete; sternite II with 0–3 discal setae, III–VII with 4–10 discal setae sometimes arranged irregularly.

Comments.
The females of this species have the median dorsal setae on tergite IX stout, arising in a posterior position and extending well beyond the posterior margin of the tergite. The male has processes on the ninth tergite that are similar to those of
A. mnestes
, but the sternites bear pore plates. Two females have also been seen from Kununurra in the north of Western
Australia
that probably represent this species.
