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 ocellus10 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 15B). Baeus hallarakeri is named in honour of Torstein Hallaraker, Senior, of Norway.
