Naumann & J. Cardale (ANIC). Description. Female. Mean length 0.82 mm (0.74–0.86; n = 5); body and head range from black to dark brown, legs and antennae yellow with darker markings on dorsal surfaces. Head. 2.25 (2.17–2.38) x as wide as inter-ocular distance, and 1.86 (1.59 –2.00) x as wide as long; medial ocellus 15 μm in diameter, 82 (80–90) μm from posterior head margin; lateral ocelli touching eye margin, 20 μm from posterior head margin; lateral ocelli very close to ( 15 μm in length. Metasoma. T 2 length 0.90 (0.89–0.91) x width, sculpturing coriarious, pilosity mostly sparse, but can be of moderate density in medial anterior areas, is mostly of medium length, often bordering on short, which it can be in areas; T 3 coriarious anteriorly with wide smooth, nitid band along posterior margin, one row of setae present along posterior extremity of sculpturing; T 4 glabrous. Comments. Baeus matthewi is clearly recognisable from other species because of its large hind femoral spine that is very distinct under stereo-light microscopey. The only other species to possess such large spines is B. vulcanus, which also has large propodeal spiracles (opening? 20 μm in diameter) that are clearly distinguishable from the smaller spiracles of B. matthewi. This species has mainly been collected along Cape York Peninsula as far south as Mareeba, except for several specimens collected from the Flinders Ranges in South Australia, and from Canberra (Fig. 16 A). The contrasting climatic conditions among the regions possibly indicates that the distribution of Baeus spp. is largely determined by host distribution rather than environmental conditions. This species is named after the brother of the senior author, Mr Matthew Stevens.Published as part of Stevens, Nicholas B. & Austin, Andrew D., 2007, Systematics, distribution and biology of the Australian ' micro-flea' wasps, Baeus spp. (Hymenoptera: Scelionidae): parasitoids of spider eggs, pp. 1-45 in Zootaxa 1499 on pages 27-29, DOI: 10.5281/zenodo.17708

Mesosoma. Length 0.66 (0.64–0.68) x width; mesoscutum and mesoscutellum imbricate, pilosity dense and medium in length throughout; posterior margin of mesoscutellum broadly extending over dorsal propodeum to beyond anterior margin of T 2; mesoscutum length 0.49 (0.45–0.52) x width, 0.65 (0.63–0.69) x mesosoma length and 1.87 (1.67–2.20) x mesoscutellum length; sculpturing of dorso-lateral mesopleuron and propodeum anterior to spiracle confused, region of latero-dorsal propodeum, posterior of spiracle, bearing short carinae, each with a long bristle posteriorly, and a longer, more distinct carina ventral to spiracle that is not prominent enough to delineate lateral propodeum from dorsal propodeum; propodeal spiracle opening small and ovoid; posterior margin of metapleuron distinct, straight, and short, ending dorsal to level of anterolateral margin of T 2, posterior region of metapleuron level with anterior region of lateral propodeum; hind femoral spine absent. Metasoma.

Comments. As the names suggests, B. tropaeumusdensus is similar to B. tropaeumusbrevis in that the mesoscutellum extends over the propodeum reaching the anterior margin of T 2. Therefore, the first part of the name is similarly derived (see C omments above) and the second part, densus, means dense and thick in Latin, which relates to the species’ pilosity. Although not commonly collected, B. tropaeumusdensus has a widespread distribution (Fig. 17 B).Published as part of Stevens, Nicholas B. & Austin, Andrew D., 2007, Systematics, distribution and biology of the Australian ' micro-flea' wasps, Baeus spp. (Hymenoptera: Scelionidae): parasitoids of spider eggs, pp. 1-45 in Zootaxa 1499 on pages 41-42, DOI: 10.5281/zenodo.17708

Mesosoma. Very compact, length 0.31 (0.27–0.33) x width; mesoscutum and mesoscutellum transverse in appearance; mesoscutum finely coriarious, pilosity very sparse, although small patches of medium density can occur, mixture of short and medium length, medium length setae in range of 10–15 μm, not exceeding 20 μm; anterior half mesoscutellum faintly coriarious, posterior half smooth, only one row setae present, short, dense medially, moderately dense laterally; propodeum glabrous medio-dorsally; mesoscutum length 0.23 (0.20–0.26) x width, 0.54 (0.50–0.60) x mesosoma length and 1.73 (1.50–2.25) x mesoscutellum length; mesoscutellum 2.2 (2.0– 2.5) x as long as propodeum; sculpturing of entire dorso-lateral mesosoma scrobiculate, except for pronotum and thin glabrous band along posterior margin of propodeum; propodeal spiracle difficult to see within sculpturing laterally, more visible postero-laterally, opening small and ovoid; prominent laterally projecting carina not present on dorso-lateral propodeum (Fig. 13 B); posterior margin of metapleuron distinct, curved dorsally and ending ventral to level of antero-lateral margin of T 2, ventro-posterior margin elevated from ventro-anterior margin of lateral propodeum; hind femoral spine absent.

Comments. This species is similar in size, shape, and pilosity to B. arthuri. The genal shape of both species are similar, with the posterior and anterior margins being strongly convergent medially. However, B. scrobiculus is easily identifiable by the extensive scrobiculate sculpturing of the dorso-lateral propodeum. It is this distinctive feature that the species name is derived from the Latin word scrobiculus, meaning extensive scrobiculation. Baeus scrobiculus is recorded from northern Queensland, a region that has been extensively sampled (Fig. 16 D). However, it has not been commonly collected and is described here from five specimens only.Published as part of Stevens, Nicholas B. & Austin, Andrew D., 2007, Systematics, distribution and biology of the Australian ' micro-flea' wasps, Baeus spp. (Hymenoptera: Scelionidae): parasitoids of spider eggs, pp. 1-45 in Zootaxa 1499 on pages 35-37, DOI: 10.5281/zenodo.17708

The holotype, along with 28 female and four male paratypes, were all reared from a single, unidentified host egg-sac. Therefore, <i>B. arthuri</i> is one of only a few Australian <i>Baeus</i> species that has reliably associated males. <i>Baeus arthuri</i> is confined to the more tropical areas of northern Australia (Fig 15 A) and extends to Papua New Guinea and Fiji.
