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 T2; posterior margin metapleuron elevated from anterior region of propodeum; hind femoral spine absent.
Metasoma. T2 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; T3 smooth and nitid, bearing one row of setae; T4 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 B). Baeus hallarakeri is named in honour of Torstein Hallaraker, Senior, of Norway.
