description: <i>Maurillus australis</i> Smith, 1855 (Fig. 2) <i>Maurillus australis</i> Smith, 1855: 170; Evans 1972: 249, &amp;female;. <i>Pompilus australiensis</i> Dalla Torre, 1897: 275 (new name for <i>australis</i> Smith preoccupied in <i>Pompilus</i>). Material examined <i>Holotype</i> &amp;female; ‘N. Holl., N.W. Coast’ ‘ B.M. TYPE HYM. 19.257 ’ (NHML). Diagnosis <i>Female</i> Head dark ferruginous above ocelli (Fig. 2a,e), its height greater than width; distance from eye toptovertex crest, in profile, about two-thirds of eye height (Fig. 2c); gena in dorsal view very thick (Fig. 2e), OOcD/POD = ~3.0; gena, in profile, 1.2× as broad as eye (Fig. 2c); and T1–5 with a pair of patches of dense golden pubescence posterolaterally (Fig. 2f). Redescription <i>Female</i> Based on holotype. Length 20 mm; fore wing 13.6 mm. Body and legs black or dark rufous, except for dark ferruginous upper frons, tibiae and tarsi. Wings infuscate with paler spot in subdiscal cell 1 and weakly defined, oblique, paler band apically to SMC3 (Fig. 2g). Body and legs with pubescence mainly back, but silvery-white on lower frons laterally to antennal sockets, clypeus, upper gena, side of scutellum and propodeum posterolaterally; upper half of head with golden pubescence. Head 0.98× as broad as high (Fig. 2a). Frons with median sulcus strongly impressed below and barely reaching anterior ocellus. MID 2.3× as broad as both eyes together. Antennocular line concave immediately laterally to antennal socket (Fig. 2e). Inner orbits subparallel but weakly emarginate above middle. UID: MID:LID = 9.5:10:9.9. MID 0.7× TFD. POL:OOL = 1:1.7. Clypeus 2.8× as wide as long; lateral and anterior rims smooth and polished (Fig. 2b); lateral margin weakly slanted, apicolateral corner narrowly rounded. Labrum broadly rounded apically. Scape roughly triangular in cross-section with U-shaped carinae on both median and lateral faces (Fig. 2d), surfaces insidethem concave. Scape:pedicel:fl1:fl2 = 10:1.8:10:7.6. Fl1 3.8× as long as wide, 0.5× UID. Pronotum with posterior margin subangulate medially. Mesoscutum flattened with posterolateral margin narrowly rounded. Metapostnotum very short, less than 0.2× as long as metanotum at midline, not constricted medially. Propodeum, in dorsal view, 1.6× as wide as long; dorsum convex with coarse, transverse, somewhat reticulate rugae and indistinct median groove; its sides arcuately convex, slightly broadened subapically; declivity with strong transverse rugae (Fig. 2h). Longer spur of hind tibia 0.4× hind tarsomere 1. Fore and hind wings as shown in Fig. 2g. Marginal cell removed from wing tip by 0.6× its own length. SMC2: SMC3 = 1:1.1 on vein <i>M</i>, 1:0.9 on vein <i>Rs</i>. SMC2 0.6× as high as long, narrowed on vein <i>Rs</i> by 0.7× its length on vein <i>M</i>, receiving crossvein <i>1m-cu</i> at basal 0.6. SMC3 0.7× as high as long, narrowed on vein <i>Rs</i> by 0.6× its length on vein <i>M</i>, receiving crossvein <i>2m-cu</i> at basal 0.5. Crossvein <i>2rs-m</i> bisinuate. Crossvein <i>cu-a</i> originating distal to point of separation of vein <i>M + CuA</i> and oblique to vein <i>A</i>. Hind wing crossvein <i>rs-m</i> sinuate, meeting vein <i>M</i> obliquely. Crossvein <i>cu-a</i> originating at point of separation of vein <i>M + CuA</i>. Metasoma short, almost as long as mesosoma, much broader than latter, somewhat compressed dorsoventrally (Fig. 2f). T6 with many long sparse bristles. S6 slightly compressed laterally. <i>Male</i> Unknown. Distribution Australia (North West Coast).
