Description (holotype, male). Body length 2.1 mm. Body dark reddish brown, elytra unicolourous; legs and antennae reddish.
Antero-lateral margins of frons simple. Gular rugules of different sizes, anteriorly larger, contiguous and ordered as in Figs 138, 139 View Figs 133–140. 133 . Clypeal granules indistinct. Setation of head vertex mostly short, fine and appressed, with some longer setae more raised medially, distinctly coarser ventro-laterally; antero-lateral sides (between eyes and antennal sockets) with coarse, bristly and conspicuously ordered setation ( Fig. 133 View Figs 133–140. 133 ). Antennae rather moderately long; antennomeres II and III about 1.8 times as long as wide, IV and V somewhat more robust, X nearly 1.2 times as long as wide; setation mostly fine, distinctly coarser and longer on basal antennomere.
Pronotum globose to moderately transverse, 1.4 times as long as wide, its lateral margins rather evenly convex in dorsal view; posterior collar narrow and inconspicuous. Pronotal horn rather robust and wide, its posterior angles indicated in dorsal view; horn margins armed with 4 lobules on each side, apical lobule broadly rounded and slightly emarginate medially; horn crest very distinct, raised, with few mostly coarse rugules on margins; submarginal rugules rather distinct, mostly well-spaced; median rugules largely fused and forming longitudinal sculpture (connected with one of rugules of crest margin), several smaller granules present posteriorly. Setation whitish to greyish, scaly, appressed to subdecumbent, distinctly finer and hairy, inconspicuous on pronotal horn dorsally; scales on pronotal disc clearly of two sizes, larger scales slightly raised, distinctly truncate apically; antebasal paired setae absent medially and probably present laterally, difficult to distinguish laterally from another tactile (4 on each side).
Elytra 1.8 times as long as wide; omoplates and postbasal impression absent. Setation greyish to brownish, forming rather vague brownish markings, scaly and appressed, evenly ordered; scales elongate, rounded to subtruncate apically, very densely spaced (surface barely visible); scattered tactile setae absent, but several short erect setae present on humeri and very near base.
Male characters. Sternum VII simple. Tergum VIII and aedeagus as in Figs 108, 109 View Figs 104–110. 104–105 .
Variation. Body length (♂ ♀) 1.9–2.1 mm. Pronotal horn with 3–5 lobules on each side; apical lobule rarely bilobed. Brownish markings of elytra vague to rather distinct; brownish and greyish scales may be partly mixed in basal half.
Differential diagnosis. Mecynotarsus setulosus sp. nov. may somewhat resemble small specimens of M. kingii or M. exophthalmus sp. nov. by body shape, morphology of the pronotal horn, and setation (dense, appressed uniform scales on elytra, numerous tactile setae laterally on pronotum), but differs by the coarse, bristly and conspicuously ordered setation of the antero-lateral sides of the head ( Fig. 133 View Figs 133–140. 133 ), as well as by the male characters (cf. Figs 108, 109 View Figs 104–110. 104–105 versus 67, 68 and 47, 48).
Etymology. The species name is a Latin adjective, setulosus , -a, -um (= bearing many small bristles); named in reference to the peculiar setation of the head.
Distribution. Australia: New South Wales, Northern Territory, Queensland, South Australia.
