Redescription (male, Gawler, NMPC). Body length 2.6 mm. Body brown, at places with reddish tinge, elytra unicolorous; legs and antennae pale reddish brown.

Antero-lateral margins of frons simple, at most slightly raised. Gular rugules of different sizes, anteriorly ordered as in Fig. 138 . Clypeal granules indistinct. Setation of head vertex mostly short and fine, appressed, with some longer suberect setae medially, especially near base. Antennae rather long; antennomeres III–V about 1.8 times, X 1.4 times as long as wide; setation generally rather hairy, somewhat coarser on basal antennomeres.

Pronotum 1.6 times as long as wide, its lateral margins somewhat unevenly shaped, slightly angled at widest point and straight while narrowing towards base in dorsal view; posterior collar narrow but distinct. Pronotal horn rather robust, moderately wide, its posterior angles obsolete in dorsal view; horn margins armed with 4 mostly wide lobules on each side; horn crest distinct, clearly raised, rather narrow, with coarse, separate rugules on margins; submarginal rugules numerous, somewhat unevenly spaced; single, somewhat uneven, longitudinal median rugule. Setation mostly whitish, pale brownish with slight cupreous reflection dorsally, rather coarsely hairy (not really scaly), finer on pronotal horn dorsally, but even here rather distinct; setae on pronotal disc of two sizes, shorter and appressed or longer and subdecumbent, both rather linear and truncate apically; antebasal paired setae rather long and conspicuous laterally, absent medially, another tactile setae absent.

Elytra 1.7 times as long as wide; omoplates and postbasal impression absent. Setation whitish and brownish, forming rather distinct transverse bands / spots ( Fig. 199 ), uniformly short and appressed; setae coarsely hairy to scaly (linear), truncate apically, evenly ordered and sparse (surface clearly visible); erect tactile setae absent.

Male characters. Sternum VII distinctly modified ( Fig. 69 ). Tergum VIII and aedeagus as in Figs 70–71 .

Variation. Body length (♂ ♀) 2.1–2.9 mm. Pronotal horn with 4–5 lobules on each side. Body typically brown black (old specimens from Gawler seem to be faded).

Differential diagnosis. Mecynotarsus kreusleri can be easily recognized by the body colouration (brown black with rather contrastingly whitish setose bands / spots on the elytra), elytral setae / scales linear, truncate apically and distinctly spaced (surface visible), as well as by the male characters (modified sternum VII and rather distinctive shape of parameres).

Distribution. Australia: Australian Capital Territory (new record), New South Wales ( LEA 1895), Queensland (MAC LEAY 1872), South Australia ( KING 1869, UHMANN 2007), Victoria (new record).
