Anagonia uptoni sp. nov.

Figs 66–68

Types. Holotype male in ANIC no. 29-029369, 18 mi W of Mogumber, WA, 13 Apr. 1968, IFBC & MSU; terminalia in tube 325. Paratypes (all males):— Western Australia: Wyndham, 4 Jan. 1930, T. G. Campbell, T.t. 72; 21 mi W of Kojunup, 21 Mar. 1968, IFBC & MSU, T.t. 359; 5 km SE of Millstream HS, 21°37'S 117°06'E, 17 Apr. 1971, IFBC & MSU, T.t. 2203; 14°49'S 128°49'E, Carson Escarpment, 9–15 Aug. 1975, IFBC & MSU, T.t. 459.— Australian Capital Territory: Black Mtn, light trap, 11 Jan. 1958, IFBC, T.t. 127.

Very similar to A. perplexa, but rather smaller and differing as follows:

Male. Head. Width 1.8–2.6, mean 2.16 mm. Ivb-VbE 1.2–1.4, mean 1.30. Eye sparsely, finely or not at all haired. Ocellar setae sometimes not developed. Parafacial with ground colour very pale in tropical specimens, but only along anterior margin in those from southern areas.

Thorax. Apical scutellars directed upwards.

Legs. Tibiae concolorous with femora. Hindtibia with pd1 usually short, Pd1/Sdd 0.4–1.0, mean 0.77.

Terminalia ( Figs 66–68 , 79). Cercus with basal lobe prominent, rounded, separated by a relatively large, membranous “notch” from apical part, with a patch of fine microtrichiae on ventral part of base; apical part straight, almost rod-like, about 1.5–2.0 times as long as basal part, with stout preapical tuft of spiny setulae and several scattered along the shaft, apex lying at about the bend of surstylus. Surstylus bent at about 2 ⁄ 3 its length from base (about ½ in other species).

Female. Not recognized.

Distribution. Most of the few specimens known are from Western Australia, but there is also one from ACT.

Biology. All that is known is that adults come to light.

Notes. Apart from the expected difference in ratio Ivb/b-E, due to overall size difference, A. uptoni differs from the other relatively small species, A. minor, in Ivb independent of size. It is noticeable that specimens from the north of Western Australia are distinctly paler than those from the south.

Named for my colleague Murray Upton, whose passion for Lepidoptera never precluded collection of many interesting Diptera.
