Key to adults of Binburrum Pollock, 1995 (modified from Pollock 1995)
1. Epipleuron distinct to elytral apex .......................................................................................................................... 2
–. Epipleuron traceable only to apical fourth of elytron .........................................................................................3
2. Usually multicoloured, head black to light brown, pronotum orange to dark brown, elytra yellowish brown to black ( Fig. 1C View Fig ); frontoclypeal area distinctly, largely depressed; antennae extended to elytral midlength; elytra with length ca. 4.4–5.0 × pronotal length; male genitalia: tegmen with apicale narrowed apicad in dorsal view and obtusely pointed apically in lateral view ( Fig. 4A–B View Fig ), accessory lobes extended slightly beyond apicale; distribution: Victoria .................................. Binburrum concavifrons Pollock, 1995
–. Unicoloured, entirely dark brown ( Fig. 1F–G View Fig ); frontoclypeal area slightly depressed; antennae extended to one-fifth of elytra; elytra with length ca. 6.1–6.3 × pronotal length; male genitalia: apicale nearly parallel laterally in dorsal view and rounded apically in lateral view ( Fig. 4C–H View Fig ), accessory lobes largely extended beyond apicale; distribution: South Australia ............................................ Binburrum articuno new species
3. Pronotum of male relatively broad, the same width or only slightly narrower than head; male genitalia: apicale distinctly cleft apically, nearly straight, not deflexed away from accessory lobes in lateral view ( Fig. 6B, D, F View Fig ) ............................................................................................................................................................... 4
–. Pronotum of male relatively narrow, distinctly narrower than head; male genitalia: apicale not or shallowly concave apically, deflexed away from accessory lobes in lateral view ( Fig. 5B View Fig ) .............................. 6
4. Lateral pronotal margins usually with several small, setigerous tubercles ( Fig. 1E View Fig ); elytral punctures large, with interpuncture distance slightly less than puncture diameter; male genitalia: apicale subequal to basale in length, deeply cleft apically, broad, round-sided and slightly narrowed apicad in lateral view ( Fig. 6C–D View Fig ); distribution: Tasmania, Victoria, and south New South Wales ................................. Binburrum ruficollis ( Champion, 1895)
–. Lateral pronotal margins without tubercles; elytral punctures smaller, with interpuncture distance subequal to puncture diameter; male genitalia: apicale slightly longer than basale, moderately cleft apically, broad, straight-sided and distinctly narrowed apicad in lateral view; distribution: New South Wales and Queensland .................................................................................................................................................................. 5
5. Pronotal disc regularly and densely punctate; male genitalia: apicale slightly narrowed apicad ( Fig. 6A–B View Fig ), accessory lobes slightly extended beyond apicale, median lobe short, stout ( Fig. 8A–B View Fig ); distribution: New South Wales and south Queensland ............................................................ Binburrum bifoveicollis ( Lea, 1917)
–. Pronotal disc irregularly and relatively sparsely punctate, with medial region more glabrous ( Fig. 3D View Fig ); male genitalia: apicale distinctly narrowed apicad ( Fig. 6E–F View Fig ), accessory lobes largely extended beyond apicale, median lobe elongate, slender ( Fig. 8E–F View Fig ); distribution: northern Queensland ............................................................................................................................ Binburrum zapdos new species
6. Unicoloured ( Fig. 1A View Fig ); elytra flat dorsally, sloped near apex only; male genitalia: apicale shorter than basale; distribution: northern New South Wales and southern Queensland ...................................................................................................... Binburrum angusticollis Pollock, 1995
–. Bicoloured, body orange with large, broad piceous fascia on elytra; elytra distinctly sloped near midlength; male genitalia: apicale the same as or longer than basale; distribution: Victoria and northern Queensland ...7
7. Body dark orange, with fascia in middle of elytra ( Fig. 1D View Fig ); head and pronotum sparsely punctate, with interpuncture distance the same as or greater than puncture diameter, punctures shallow, fine; elytral punctures small, longitudinally subelliptical, with interpuncture distance greater than puncture diameter; male genitalia: apicale longer than basale, hoodlike, not cleft apically in dorsal view and sinuate, distinctly deflexed away from accessory lobes in lateral view, accessory lobes inserted in proximal half of apicale, not extended beyond apicale, median lobe parallel laterally, slightly enlarged, bifid apically; distribution: Victoria .................................................................................................. Binburrum ephippiatum ( Wilson, 1926)
–. Body light orange, with fascia in posterior half of elytra ( Fig. 1H View Fig ); head and pronotum densely punctate, with interpuncture distance much less than puncture diameter, punctures deep, coarse ( Figs. 2C View Fig , 3C View Fig ); elytral punctures large, rounded, with interpuncture distance subequal to puncture diameter; male genitalia: apicale subequal to basale in length, concave, not deeply cleft apically in dorsal view and nearly straight, merely slightly deflexed away from accessory lobes in lateral view ( Fig. 5 View Fig ), accessory lobes inserted in distal one-third of apicale, extended beyond apicale, median lobe slightly narrowed apicad ( Fig. 5A, C View Fig ); distribution: northern Queensland .....................................
