Anagonia teratostylus sp. nov.

Fig. 76 View Figs 75–78

Types. Holotype male in ANIC no. 29-029368, Mt Solitaire, 30 km WNW of Alice Springs, NT, 29 Sep. 1978, MSU and R. A. Barrett, terminalia in tube 2500. Paratypes (all males):— Northern Territory: 32 km WNW ofAlice Springs, 8 Oct. 1978, DHC, at light, T.t. 2230; 2 males, Entire Ck, 155 km ENE of Alice Springs, 13 Oct. 1978, DHC, T.t. 2249, 2615.— Queensland: Moura, F. D. Page & L. Rigby, T.t. 2614.

A small dark species. Only the male is known, practically identical to A. opaca in size, colouration and parameters of head shape, but rather less bristly and differing otherwise as follows:

Head. Eye moderately to sparsely haired; ocellar setae well developed, but not as stout as in opaca. Hindtibia with Pd1 long, ratio Pd1/Sdd 1.0–1.1, mean 1.08. Abdomen without differentiated submedian marginal bristles on tergite 3.

Terminalia ( Fig. 76 View Figs 75–78 ). Syntergosternite 6–8 very narrow, its posterior margin steeply declivitous, almost vertical, its surface with extensive areas of very fine setulae. In lateral view surstylus of most unusual shape, broad and foliate on basal 2 ⁄ 3, with a deep subapical notch on anterior edge setting off a more or less thumb-like apical part. Cercus with basal lobe only slightly protruding, about as large as apical part, both with extensive areas of profuse, minute, fine setulae. Epiphallus well developed, tapering. Lobes of S5 with small, stout denticles instead of the usual setae.

Distribution. The few specimens from the vicinity of Alice

Springs in the Northern Territory were matched, surprisingly, by one from central Queensland.

Biology. The NT specimens were taken at light.

Notes. The specific identity is guaranteed by the extraordinary terminalia, but there is little else to assist in identification. The name refers to the most unusual surstylus.
