Compact, higher and wider than long (Fig. 10A and 11D); both fore- and hindwings reduced to minute sclerotized plates that are often overlooked because they neatly fit into recesses beneath lateral margins of mesoscutum and mesoscutellum respectively, only marginally larger than tegula (Fig. 4A and 7B-F); pronotum visible latero-dorsally, but not medio-dorsally, dorso-posterior corner of pronotum bearing protuberance(Fig. 7E); mesoscutum much wider than long; mesoscutellum transverse, approximately one-third length of mesoscutum (Fig. 4B); metanotum greatly reduced, hidden beneath mesoscutellum so not visible (cf. Figs 4A and B to Figs 5A and B); posterior surface of propodeum vertical, dorsal surface forming thin transverse band, posterior margin extending over anterior margin of T2 (Figs 4A and B); dorsal metapleuron fused with propodeum to varying degrees (Figs 7A-F); coxae large, anterior surface densely covered with stout bristles; legs longer than mesosoma and metasoma combined, hind leg longest; hind leg femoral spine present or absent (sometimes difficult to see even at high magnification) (Figs 6C and D).</paragraph>

is supported by eight critical characters associated with the female sex: 1) the female metasoma is short, convex, wide anteriorly and broadly abutted against the vertical surface of the mesosoma so the body appears to be rounded and fused (Figs 4A & B), 2) T1 and S1 are wafer thin and form the semi-vertical anterior surface of the metasoma (Fig. 3A); because of this arrangement, T1 is not visible dorsally (Fig. 4B), 3) T2 is the largest tergite, comprising at least 0.6 times the length of the metasoma (Fig. 4A & B), 4) the laterotergites of the metasoma wide and free, not incised into a submarginal groove as in

(Fig. 3A cf. 3B), 5) the propodeum is vertical and forms the whole of the posterior surface of the mesosoma, 6) the metanotum is reduced and hidden below the mesoscutellum, 7) the maxillary and mandibular palps are reduced to a single segment, and 8) the wings are micropterous, i.e. both fore- and hindwings reduced to minute sclerotized plates, the forewing only slightly larger than the tegula, therefore, often referred to as ‘wingless’ (Fig. 4A, 7B-F). In addition, the male is characterized by having the forewing narrow so that the anterior and posterior margins are almost parallel, the submarginal + marginal veins only about 0.4 times the length of the wing, and a basal vein is usually present (Fig. 2).

species exists within the peripheral mesic environments of the continent, a common pattern exhibited by their hosts (Raven 1988). Of the 20 species treated here, 55% are endemic to a single biogeographic subregion, with the highest level of endemism found in the Kosciuskan subregion (25%) (Fig. 1). The eastern seaboard of the continent, from northern Queensland to southern New South Wales, exhibit the greatest species richness (Fig. 1) and share the most number of species (Table 3). The lowest number of species occurs in the South-Western and Eyrean subregions which have no endemic taxa, although these areas are also the poorest surveyed. In addition, we have recognized a further eight likely new species, but have refrained from describing them because of the limited material available and/or their poor condition. Five of these species are from the Kosciuskan subregion, two of which also occur in other subregions, one in the South-West, the other extending into the Torresian subregion. The Tasmanian, Timorian, and Torresian subregions each have a single undescribed species. It is likely that numerous additional species will be discovered in the future as more long-term collecting using a range of techniques is undertaken in specific habitats.
