Sinclair (1 ɗ, CNC); Blue Mountains National Park, Grand Canyon, rainforest stream, 25.xii.1993, B.J. Sinclair (1 ɗ, CNC); Brown Mountain, 50 kmW Bega, 1100 m, 28.i.1984, L. Masner (1 ɗ, CNC).

Recognition. This species is distinguished by the following features: frons and ocellar triangle with patches of tomentum, occiput completely clothed in tomentum, hypandrium cup-like, pair of rods dorsal to ejaculatory apodeme, left surstylus with broad base and right surstylus with long apical seta.

Description. Wing length 2.2 mm.

Male. Scape and pedicel yellow, postpedicel dark from various angles. Frons and ocellar triangle faintly shiny, with patches of tomentum. Occiput clothed in grey tomentum; 3 long postocular bristles longer than ocellar bristles. Mouthparts yellow, including palpus.

Scutum dark and shiny; apex of postpronotal lobe yellow; lower notopleuron, postalar ridge and scutellum with grey tomentum. Acrostichals biserial, subequal in length with dc, extending length of scutum; 1 pprn with several long setulae; 1 npl with many setulae; 1 long pal; dc uniserial; 2 pairs sctl, apical pair stouter and five times longer than lateral.

Fore and midlegs yellow, except tarsomere 5 darker. Fore tibia expanded about gland; setae surrounding gland pale. Hind femur as pale as anterior legs basally, darker on middle third, paler apically. Hind tibia pale basally; distal two-thirds very dark, nearly black. Hind tarsomeres dark; tarsomere 1 with 3–4 pairs of spinelike ventral setae, shorter than width of tarsomere; tarsomeres 2–3 with several stout, dark ventral setae.

Abdomen clothed in thin tomentum. Hypandrium cup-like ( Fig. 7 ), long and prolonged distally, apex straight. Left epandrial lamella with sharp spine-like projection at base of apical spine-like seta; spine-like seta slightly shorter than left surstylus ( Fig. 8 ). Left surstylus subtriangular with broad base; right surstylus finger-like, nearly parallel-sided, longer than left surstylus, with long apical seta. Hypoproct with short median projection. Pair of sclerotized rods dorsal to ejaculatory apodeme. Distiphallus with apical third spinose.

Female. Unknown.

Distribution. This species is known from moist forest habitats at about 1000 m in eastern New South Wales, from the southern coastal ranges, the Blue Mountains and the McPherson Range near the Queensland border.

Etymology. The specific name is derived from the Greek anatolikos (eastern), in reference to the eastern Australian distribution of this species.
