Anagonia errator sp. nov.

Fig. 80

Types. Holotype male in ANIC no. 29-029360, Illungnarra waterhole, 90 km SSW of Urandangi, NT, 15 Oct. 1978, DHC (at light), terminalia displayed in situ. Paratypes (all males):— Northern Territory: 2 specs. as for holotype, T.t. 2498 and 2215; 22 km WSW of Borroloola, 2 Nov. 1975, MSU, T.t. 465; Caranbirini waterhole, 33 km SW of Borroloola, 21 Apr. 1976, DHC, T.t. 2205.— Australian Capital Territory: Black Mtn, light trap, 17 Jan. 1962, IFBC, T.t. 140; the same, but 9 Jan. 1964, T.t. 147.— Western Australia: Mt Claremont, Perth, 10 Apr. 1968, IFBC & MSU, T.t. 344; 16°08'S 136°06'E.

Male. Externally, practically identical to A. uptoni, differing mainly in the terminalia. Also, rather larger, HdW 2.2–2.9, mean 2.61 mm; Ivb/Vb-E 1.1–1.2, mean 1.16.

Terminalia (Fig. 80). Rather similar to A. perplexa, but (in lateral view) cercus with basal lobe rather less prominent, with a (usually) small patch of microtrichiae centrally at base, and separated from apical part by a distinct “notch”. Apical part a little shorter than basal part, its apex at about the bend of the surstylus, curved and “thumb-like”, with subapical patch (rather than tuft) of setulae covering about 1 ⁄ 3 its length, rest of posterior surface with numerous microtrichiae.

Distribution. Specimens seen from Northern Territory, Western Australia and the ACT.

Biology. Most specimens were taken at light, but one was reared from larvae of the weevil, Gonipterus scutellatus.

Notes. Despite the stout similarity to A. uptoni, the fine detail of the terminalia leaves no doubt that this is a good species. The name refers to the remarkably wide geographic distribution of the few specimens seen.
