Anagonia angustifrons sp. nov.

Figs 64, 65

Types. Holotype male in ANIC no. 29-029222, 26 mi NNE of Orbost, Vic., 1300 feet, 6 Nov. 1969, IFBC, terminalia mounted on card. Paratypes (all males):— Australian Capital Territory: Cotter River, 18 Nov. 1954, Z. Liepa, T.t. 106; Lee’s Springs, 24 Feb. 1959, Z. Liepa, T.t. 466; Black Mtn, light trap, 20 Nov. 1959, IFBC, T.t. 121; the same, but 15 Oct. 1965, T.t. 136; as for holotype, but terminalia not dissected.

Extremely similar to A. perplexa, differing as follows:

Male. Head. Width 2.5–3.6, mean 2.87 mm. Frons narrow, Frw/Hdw 0.1–0.2, mean 0.16. Ivb/Vb-E 1.1–1.4, mean 1.16. Ocellar setae usually very finely developed. Some specimens with more dark hairs on the upper occiput.

Abdomen. Some specimens with submedian marginals on tergite 3 well developed.

Terminalia ( Figs 64, 65 ). Cercus with basal lobe less prominent, longer, posterior margin drawn out into a bluntpointed sublobe that covers the base of the apical part, without the fringe of microtrichiae, but with a patch of same at the dorsal half of its base. Apical part relatively longer and narrower (digitate rather than thumb-like), with a subapical patch of setulae.

Female. Not recognized.

Distribution. ACT and Victoria and presumably more widespread in southeastern Australia.

Biology. Nothing is known except that adults come to light.

Notes. The name refers to the very narrow frons, relatively the narrowest in the entire group.
