Description. Female. Mean length 0.69 mm (0.61-0.72; n= 10); body and head dark brown, legs and antennae lighter with darker markings on dorsal surfaces. Head. 1.88 (1.80-2.00) x as wide as inter-ocular distance and 1.36 (1.29-1.43) x as wide as long; medial ocellus 10 µm in diameter, 62 (60-70) µm from posterior head margin; lateral ocelli contacting eye margin, 12 (10-15) µm from posterior head margin; posterior ocellar line 1.16 (1.13-1.21) x inter-ocular distance; vertex coriarious, pilosity dense and of medium length; eyes circular, eye height 0.51 (0.48-0.59) x head height, eye width 0.49 (0.43-0.54) x length, pilosity of medium length; frontal carina prominent, reaching 0.54 (0.53- 0.56) distance to medial ocellus; lateral cristulations of malar region faint, reaching to within 10 µm of eye margin; in postero-lateral view, anterior and posterior genal margins generally marginally divergent medially, but may be parallel; anterior genal margin in contact with 0.59 (0.57-0.62) of ventral eye margin length; posterior eye margin touching hyperoccipital carina. Mesosoma. Length 0.64 (0.50-0.70) x width; mesoscutum and mesoscutellum imbricate, pilosity varies from dense to moderately dense, of medium length overall; sculpturing of propodeum ranges from glabrous to plicate medio-dorsally; mesoscutum length 0.51 (0.42-0.56) x width, 0.67 (0.63-0.73) x mesosoma length and 3.37 (2.50-4.00) x mesoscutellum length; mesoscutellum length 1.7 (1.5-2.0) x propodeum length; sculpturing of dorsal mesopleuron scrobiculate, extending ventrally of level of dorsal margin of metapleuron; sculpturing of propodeum anterior to spiracle confused, region posterior to spiracle carinulate, often with one, more distinct carina running posteriorly from medial or ventral margin of propodeal spiracle, or with two, more distinct carinae beginning from dorsal and ventral margins of spiracle; propodeal spiracle opening teardrop shaped; dorsal propodeum not delineated from lateral propodeum by distinct, laterally projecting carina, instead dorso-lateral propodeum rounded; metapleuron thin and tapered, posterior margin curving slightly medially, ending adjacent to level of antero-lateral margin of T2, medio-posterior margin elevated from anterior margin of lateral propodeum; hind femoral spine reduced. Metasoma. T2 length 0.85 (0.74-0.92) x width, sculpturing gradating from coriarious anteriorly to smooth posteriorly; pilosity gradating, anterior to posterior, from dense to moderately dense, of medium length overall; T3 and T4 glabrous except for two bristles on lateral regions of each.
Comments. Baeus murphyiis a slender species and is similar to B. hallarakeri, B. glenysaeand B. mymyae(see Comments under B. hallarakeriand B. glenysae). Baeus mymyaeis distinguishable from B. murphyiby having a longer frontal carina, shorter metapleuron, and hind femoral spines absent.
Baeus murphyioccurs in a wide range of habitats from northern Queensland, down the eastern seaboard to Tasmania and extends into South Australia and the southwestern part of the continent (Fig. 16B). Specimens have also been collected from Norfolk and Lord Howe Islands.
This species is named after Mr Kevin Murphy.
