Description (holotype, male). Body length 3.3 mm. Body reddish, pronotal disc darker, reddish brown, elytra unicoloured; legs and antennae reddish.

Antero-lateral margins of frons moderately raised / lobed near antennal insertion. Gular rugules of different sizes, anteriorly larger, ordered and fused ( Fig. 139 View Figs 133–140. 133 ). Clypeal granules minute. Setation of head vertex fine, appressed, with numerous, very long, more raised setae medially, distinctly coarser, subdecumbent ventro-laterally near eyes. Antennae rather long; antennomere I long and robust, strongly enlarged apically; antennomeres III–V about twice, X 1.3 times as long as wide; setation mostly fine, distinctly coarser on basal antennomeres, especially antennomere I conspicuously setose, with coarsely fringed apical margin and numerous long bristly setae.

Pronotum moderately transverse, 1.4 times as long as wide, its lateral margins rather strongly and evenly convex in dorsal view; posterior collar very narrow and inconspicuous. Pronotal horn robust and wide, clearly triangular, its posterior angles conspicuously projecting in dorsal view ( Fig. 147 View Figs 141–149 ); horn margins armed with 3 lobules on each side, posterior lobules very wide, apical lobule simple, widely rounded; horn crest very conspicuous, strongly raised, short and situated rather posteriorly, with rugules mostly fused and forming complete semicircular rim (single separate rugule posteriorly on each side); submarginal rugules mostly very coarse, distinctly spaced; single large, median longitudinal rugule and several minute granules scattered posteriorly. Setation scaly, whitish laterally, pale reddish dorsally; scales on pronotal disc of two sizes, shorter and appressed or longer and subdecumbent, both elongate, truncate apically and somewhat glossy; antebasal paired setae present medially, difficult to recognize laterally owing to presence of numerous long tactile setae.

Elytra 1.7 times as long as wide; omoplates and postbasal impression absent. Setation mixed whitish and reddish, and brownish, forming vague brownish marking ( Fig. 191 View Figs 186–193 ), scaly, appressed and evenly ordered; scales linear, rounded to subtruncate apically, slightly glossy and distinctly spaced (surface clearly visible, Fig. 172 View Figs 168–176 ); erect tactile setae present, more numerous and longer in basal third, especially at base and humeri, shorter and very sparsely scattered mesally, and absent in apical third.

Male characters. Sternum VII nearly simple. Tergum VIII and aedeagus as in Figs 33, 34 View Figs 33–39. 33–34 .

Variation. Body length (♂ ♀) 2.7–3.7 mm; some specimens with nearly unicolorous, whitish to pale reddish scales on elytra, brownish marking may be both absent and conspicuous; pronotal horn in the specimens from Queensland mostly subtriangular, with less projecting posterior angles ( Fig. 148 View Figs 141–149 ).

Differential diagnosis. Mecynotarsus bullatus   sp. nov. is undoubtedly close to M. hirtipennis   sp. nov. as suggested by similarity of both external (triangular pronotal horn, semicircular crest rim, numerous tactile setae), and male characters. Its specimens are usually larger and more robust than those of the latter species, and differ especially by the longer, denser and somewhat double setation of the pronotal disc, with longer scales rather subdecumbent and somewhat overlapping shorter appressed scales, by the more robust antennae (basal antennomeres), and by the evenly narrowing, arcuately divergent and apically pointed parameres.

Etymology. The Latin adjective, bullatus   , - a, -um (= bubble-like); named in reference to the peculiar rounded shape of horn crest rim.

Distribution. Australia: Queensland, Northern Territory, Western Australia.
