Redescription (paralectotype, female, SAMA). Body length 2.8 mm. Body largely reddish brown, pronotal disc distinctly darker, nearly brown black, elytra with rather vague markings, darker medially, especially in basal third, paler reddish apically and laterally.

Antero-lateral margins of frons distinctly raised to somewhat lobed near insertion of antennae ( Fig. 132 View Figs 126–132. 126–127 ). Gular rugules of different sizes, anteriorly larger, nearly contiguous and ordered similarly as in Fig. 138 View Figs 133–140. 133 . Clypeal granules rather distinct. Setation of head largely short, fine and appressed on vertex, with numerous distinctly longer, mostly raised setae in median line, somewhat coarser, subdecumbent laterally along eyes. Antennae moderately long; antennomeres III–V about twice, X 1.2 times as long as wide; setation mostly fine, distinctly coarser to scaly on three basal antennomeres, with several long, stiff setae on antennomere I.

Pronotum globose, its lateral margins rather strongly, evenly convex in dorsal view; posterior collar narrow but distinct. Pronotal horn robust and wide, subtriangular, its posterior angles distinct in dorsal view ( Fig. 154 View Figs 150–158 ); horn margins armed with 4 and 5 lobules on lateral sides, apical lobule simple; horn crest distinct, wide, with coarse rugules on margins; distinct submarginal rugules somewhat unevenly spaced; numerous median rugules of different sizes. Setation whitish, largely scaly and appressed, inconspicuous on pronotal horn dorsally; scales on pronotal disc of different sizes, widely rounded to truncate apically; antebasal paired setae present laterally and absent medially, numerous additional tactile setae present antero-laterally.

Elytra 1.7 times as long as wide; omoplates and postbasal impression absent. Setation scaly, appressed, evenly developed, whitish and brownish, forming rather distinct markings ( Fig. 198 View Figs 194–201 ); scales shortly oval, subtruncate apically, opaque, densely spaced but distinct ( Fig. 177 View Figs 177–185 ); erect tactile setae absent.

Male characters (paralectotype, ANIC). Sternum VII moderately produced and slightly emarginate apically. Tergum VIII and aedeagus as in Figs 67, 68 View Figs 67–73. 67–68 ; parameres rather strongly curved in apical third.

Variation. Body length (♂ ♀) 2.8–3.4 mm. Pronotal horn usually with four lobules on each side; median rugules sometimes fused and forming coarse sculpture. Dark markings of elytra vaguely indicated to rather distinct.

Differential diagnosis. Mecynotarsus kingii   resembles especially M. pilbarensis   sp. nov. by the similar body shape, morphology of the pronotal horn, setation, and the male characters. It can be distinguished by the somewhat prolonged frontal portion of the head, the anterolateral margins of the frons subparallel, distinctly raised to somewhat lobed near insertion of antennae ( Fig. 132 View Figs 126–132. 126–127 ), and by the apically strongly narrowed and more curved parameres (cf. Figs 68 View Figs 67–73. 67–68 versus 103).

Distribution. Australia: Australian Capital Territory (new record), New South Wales (new record), Queensland ( MACLEAY 1872), South Australia (new record).

Remarks. MACLEAY (1872) described M. kingii   from an unstated number of specimens collected near Gayndah in Queensland. The seven type specimens must be regarded as syntypes, and together represent three different species. At least some of the printed type labels were subsequently added by curators. They are stored in three institutions (AMSA, ANIC and SAMA): AMSA – two females of two clearly different species, one designated as lectotype, the other is very close or even conspecific with M. granulatus   sp. nov.; SAMA – a female in very good condition ( Fig. 198 View Figs 194–201 ), conspecific with the lectotype; ANIC – a strongly damaged torso and three males in good condition, mounted on the same label and belonging to two very close species (one of them conspecific with the lectotype, and used herein for description of male characters of M. kingii   , the other two probably specimens of M. pilicornis   sp. nov.).
