Id. by J.Armstrong ( NMV).

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.
