(125–129), males. 121, penis; 122, tegmen and parameres; 123, S9; 124, T9. 121–124 to the same scale. 125, T8 and S8; 126, sclerites of T9; 127, penis; 128, apex of S9 and tegmen with parameres; 129, enlarged penis tip, not to scale. 125–128 to the same scale. Habitus . BL 2.2–3.2 mm , BL/BW ~1.7. Similar to A. adelaidae but often bicolourous, sides of the anterior 2/ 5 of the elytra pale, the space near suture and remainder of elytra dark brown, sometimes entirely dark brown. Male . Resembles A. adelaidae but lateral rods of T9 not clubbed, ending in a simple elongate point, subterminal spine very small. S9 caudally distinctly notched. Trigonium well defined, slender, apex with narrow claw-like centema. Parameres rather massive, common base long, apices distinctly hooked. Female . None of the females taken with males of A. aculeatus has distinctly bicolourous elytra but several are faded or in poor shape. Note . The Eastern sibling of A. adelaidae , distinguished by genitalia and often by its bicolourous elytra. According to present knowledge the two close relatives are widely disjunct. Etymology . From the Latin aculeatus , provided with a needle, in reference to the needle-like subterminal spine of T9.
