Australia 100 km S Mt. Magnet (dint.Paynes Find.) 5 -X-08 leg. Daccordi (SMNS). Habitus. BL 2.6 mm, BL/BW ~ 1.7. Slender, elytra with slightly convex sides. Light brown except dark brown occiput; frontal region rufous. Punctation stronger on pronotum than on elytra, normal. Semi-erect pilosity colourless. Male. T 8 caudally slightly concave, middle portion along hind margin unsclerotized. Fine setation only on sclerotization, no microtrichia. S 8 a delicate narrow V-shaped sclerite. T 9 represented by very long gently inwardly curved lateral rods in continuation of straight apodemes. A short subterminal style forks out of apex of rod. S 9 barely sclerotized, base not visible. Plate with subterminal constriction, caudal portion with slender setae on sides, distally with shallow notch between pointed corners. Tegmen simple, V-shaped, supporting inwardly curved slender parameres with tips connected to a membrane and thereby appearing a little hooked. Penis basally wider than distally, the basal frame narrow, the distal part only basally with narrow flange, apex a flat wide screen. Trigonium not nearly filling foramen, short, pyramidal, centema large, no apical spicules. Female. Not distinctive. A straight lightly sclerotized smooth tube inside base of ovipositor. No prehensor, no receptacular armature. Notes. Differs from other members of the adelaidae -group by apodemes of T 9 much shorter than the caudal rods they support. Etymology. The Latin name means ���carrier of a spicule���, a reference to the outgrowth on the rod of T 9. Published as part of Zwick, Peter, 2013, Australian Marsh Beetles (Coleoptera: Scirtidae) 4.
