(Figs 1–8, 12)
Differential diagnosis. Only the cetoniine genera Diaphonia Newman, 1840 and Tapinoschema Thomson, 1880 exhibit numerous similarities with Grandaustralis (Table 1).
Type species. Grandaustralis boomerang new species, here designated.
Description. Male (Figs 1, 3–6, 12). Head (Fig. 3). Clypeus trapezoidal; anterior margin wider than base; anterior and lateral margins linear, abruptly and greatly elevated above disc; anterior margin of mentum level with anterior margin of clypeus. Antenna with 10 antennomeres; scape globular; club with 3 antennomeres, arcuate, longer than antennomeres 1–7, as long as head. Thorax. Pronotum length and width subequal, densely, coarsely punctate, punctures becoming coalesced apically; base not produced laterally, narrowed, creating approximately parallel basolateral margins, visibly exposing mesepimeron; basomedian lobe weakly produced. Scutellum slightly longer than wide, apex acute. Elytron with indistinct costae which are not raised; subhumeral arch almost linear when viewed dorsally; surface coarsely punctate, punctures often coalesced, forming indistinct striae; bearing sparse, short, erect setae; epipleural pilosity terminating prior to apex. Preprosternum produced into strongly elevated keel. Mesometasternal process (Fig. 7) undeveloped laterally or distally, not reaching anterior margin of mesocoxa. Legs. (Fig. 6). Protibia tridentate; apical tooth and apical spur surpassing apex of first protarsomere. Protarsal claws equal, approximately 4/5 length of protarsomere 5. Mesotibia linear, distally weakly divergent; dorsal surface flat, ungrooved; bidentate, with acute median and premedian teeth; apex bispinose, bearing 2 acute spurs that surpass apex of distal spines, with deep medial notch. Mesotarsomere apices bearing long setae on proximal and ventral sides. Mesotarsal claws equal, approximately 4/5 length of mesotarsomere 5. Metatibia divergent to midlength then linear; dorsal surface flat, ungrooved; unidentate with broad, apically arcuate tooth at midlength; apex trispinose, with shallow arcuate notches, bearing 2 acute spurs which surpass apical spines. Metatarsal claws equal, approximately 4/5 length of metatarsomere 5. Metatarsomere apices bearing a long seta on dorsal and ventral surface of proximal side.
Character Grandaustralis Diaphonia Tapinoschema
Mesometasternal undeveloped moderately to greatly expanded elongate, well developed
process laterally
Abdomen. Sternites in lateral view concave. Pygidial length:width ratio 1:2; surface evenly, broadly arcuate in dorsal view, in lateral view base flat to past midlength then evenly arcuate to apex. Genitalia (Fig. 8). Parameres less than half length of phallobase, basally trapezoidal with a deep, paramedial groove on each side, each paramere parallel to apex, in lateral view linear to apex.
Female (Fig. 2). Differs from male in the following characters. Antennal club shorter, as long as antennomeres 2–7. Pygidium bulbous in lateral view, evenly arcuate from base to apex. Preprosternum with anterior projection. Mesotibia and metatibia with pronounced divergence distally, attaining twice tibial width, teeth longer. Metatibial spurs broader, each with rounded apex. Abdominal segments in lateral view convex.
Etymology. The main distribution of the only known species lies between the Great Southern region of Western Australia and the Great Australian Bight. The genus name is, therefore, a concatenation of Grand for the region and the historical name Australis for the Australian continent.
