Anagonia similis sp. nov.

Fig. 81

Types. Holotype male in ANIC no. 29-029367, Illungnarra waterhole, 90 km SSW of Urandangi, NT, 15 Oct. 1978, DHC (at light), terminalia in tube 2224. Paratype male:— New South Wales: Dubbo, 24 Jan. 1909, T.t. 2187 (pinned above an adult weevil, probably Gonipterus sp).

Very similar to A. errator and A. uptoni, but differing as follows:

Male. Head. Width 3.0–3.1, mean 3.05 mm. Ivb/Vb-E 1.2–1.3, mean 1.24. Postocellar setae 5–6.

Terminalia (Fig. 81). Structurally resembling A. uptoni, with apical part of cercus similarly rod-like, but basal lobe of cercus longer and narrower, almost as long as apical part, and much less prominent.

Female. Not known.

Distribution. Qld and NSW.

Biology. The association of one specimen with an adult weevil is suggestive, but inconclusive.

Notes. Although rather like a “large” form of A. uptoni, the differences seem more than enough to recognize this as a basic taxon and presumably a good species; the basal lobe of the cercus is especially distinctive. Also, the Ivb/Vb-E ratio is remarkably high for such large specimens and the postocellar setae are distinctive (although that might be spoilt by discovery of further specimens!).

The paratype, associated with an adult specimen of weevil, suggests that this may be the host. However, the evidence is very indirect, since the actual host would have no doubt been a larva.
