Holotype: Ψ, Tasmania, ' 41.19 S 147.56 E, Intake Bridge, 13–29. Jan. 1983, Tas., I. D. Naumann & J. C. Cardale, ex pantrap' ( ANIC).

Paratypes: Tasmania: 2 Ψ, same data as holotype ( ANIC) 3 Ψ, 42.12 S 146.30 E, 9 km S Bronte Park, 15.i – 3.ii. 1983, I. D. Naumann & J. C. Cardale, ex pantrap ( ANIC); 1 Ψ, 41.22 S 147.24 E, 10 km ENE of Nunamara, 12.i – 6.ii. 1983, I. D. Naumann & J. C. Cardale, ex pantrap ( ANIC); 1 Ψ, 42.10 S 146.10 E, 7 km SW by W Derwent Bridge, 16.i – 2.ii. 1983, I. D. Naumann & J. C. Cardale, ex pantrap ( ANIC).

Description. Female. Mean length 0.60 MM (0.58–0.62; n = 5); body and head brown, legs and antennae generally same as body and head but with lighter markings on ventral surfaces and apical areas of each segment.

Head. 1.83 (1.80–1.87) x as wide as inter-ocular distance, 1.85 (1.80–1.93) x as wide as long; medial ocellus 10 μm in diameter, 59 (50–65) μm from posterior head margin; lateral ocelli 3 (0–5) μm from eye margin, 20 μm from posterior head margin; posterior ocellar line equal to inter-ocular distance; vertex coriarious, pilosity mostly dense along posterior margin, moderately dense elsewhere, of medium length overall; eyes ovoid, eye height 0.53 (0.52–0.57) head height, eye width 0.46 (0.43–0.50) x eye length, pilosity of medium length; frontal carina usually not reaching 0.5 or more distance to medial ocellus (0.37–0.52); cristulations on malar region not extending to within 10 μm of eye margin; in postero-lateral view, anterior and posterior genal margins varying from parallel to divergent medially; anterior genal margin in contact with 0.70 of ventral eye margin length; posterior eye margin touching hyperoccipital carina.

Mesosoma. Length 0.75 (0.73–0.79) x width; both mesoscutum and mesoscutellum coriarious, pilosity moderately dense except anterior region of mesoscutum which is dense, of medium length overall; medio-dorsally, propodeum may be glabrous, plicate, or intermediate between the two; mesoscutum length 0.56 (0.56– 0.58) x width, 0.68 (0.67–0.69) x mesosoma length and 3.27 (2.86–3.67) x mesoscutellum length; mesoscutellum length 1.82 (1.50 –2.00) x propodeum length; sculpturing dorsal mesopleuron and dorso-lateral propodeum confused; propodeal spiracle small and ovoid; posterior suture of metapleuron curved slightly medially, extending dorsally above level of antero-lateral margin of T 2; posterior margin metapleuron elevated from anterior region of propodeum; hind femoral spine absent.

Metasoma. T 2 length 1.0 (0.93 –1.00) x width, faintly coriarious, pilosity dense in patches along anterior margin, but mostly moderately dense except towards posterior region which is sparse, setae of medium length overall; T 3 smooth and nitid, bearing one row of setae; T 4 glabrous.

Comments. Baeus hallarakeri   is similar to B. glenysae   , B. murphyi   and B. mymyae   , the most obvious difference being its larger eyes. This species is known only from Tasmania ( Fig 15 View FIGURE 15 B). Baeus hallarakeri   is named in honour of Torstein Hallaraker, Senior, of Norway.
