Description (holotype, male). Body length 3.1 mm. Head and pronotum reddish brown, elytra reddish, with darker markings; legs and antennae reddish.

Antero-lateral margins of frons slightly raised near insertion of antennae. Gular rugules of different sizes, anteriorly larger and ordered as in Fig. 138 View Figs 133–140. 133 . Clypeal granules minute, nearly indistinct. Setation of head vertex mostly fine, appressed, with some long, more erect setae medially, shorter and coarser to scaly around eyes and ventro-laterally.Antennae conspicuously long; antennomere II distinctly shorter than III, antennomeres V–VII most elongate, 2.5 times as long as wide, antennomere X nearly twice as long as wide; basal 4–5 antennomeres with coarse to scaly setation.

Pronotum 1.6 times as long as wide, its lateral margins somewhat unevenly convex in dorsal view; posterior collar very distinct; surface of pronotal disc with numerous scattered, pointed granules (sparser and coarser dorso-laterally; Fig. 152 View Figs 150–158 ), posterior collar medially with a pair of similar granules. Pronotal horn rather robust, moderately wide, subtriangular, its posterior angles moderately indicated in dorsal view ( Fig. 152 View Figs 150–158 ); horn margins armed with 4 rounded lobules on each side, apical lobule simple, widely rounded; horn crest distinct, rather wide, with coarse, separate rugules on margins; submarginal rugules numerous and distinct; 7 median rugules, rather coarse and mostly well-spaced, and some minute granules posteriorly. Setation scaly, whitish and pale reddish; scales on pronotal disc of two sizes, smaller scales appressed and whitish, larger scales subdecumbent and pale reddish, both elongate, widened and truncate apically; antebasal paired setae present both laterally and medially, somewhat difficult to recognize owing to presence of numerous additional tactile setae (especially laterally, including posterior collar).

Elytra 1.8 times as long as wide; omoplates and postbasal impression absent. Setation scaly, pale reddish to brownish, forming rather distinct markings ( Fig. 196 View Figs 194–201 ), appressed and evenly ordered; scales rather uniform, linear, subtruncate apically and very dense (surface barely visible, Fig. 175 View Figs 168–176 ); erect tactile setae absent.

Male characters. Sternum VII moderately produced and rounded medially. Tergum VIII and aedeagus as in Figs 55–57 View Figs 53–59. 53–54 .

Variation. Body length (♂ ♀) 2.9–3.1 mm. Pronotal horn with 4–5 lobules on each side; 4–8 median rugules. Dark markings on elytra more or less extensive and conspicuous.

Differential diagnosis. Mecynotarsus granulatus   sp. nov. is close especially to M. nobilis   sp. nov. and M. imitator   sp. nov. in having a granulate pronotal disc and uniformly short, rather dense setation of the elytra. It resembles the first species in male characters, but differs by the well-shaped smaller scales of the pronotal disc (bifurcate to somewhat frayed apically in M. nobilis   sp. nov.), quite uniformly appressed setation of the elytra, and by the shape of the parameres (cf. Figs 56 View Figs 53–59. 53–54 versus 83). It differs from M. imitator   sp. nov. by the somewhat more robust appearance, the rather extensive and conspicuous markings of the elytra, but primarily by the much wider, medially somewhat lobed and apically obliquely truncate parameres.

Etymology. The species name is a Latin adjective, granulatus   , -a, -um (= granulate); named in reference to the granulate pronotal disc.

Distribution. Australia: New South Wales, Northern Territory, Queensland.
