Redescription (male, Hobart, QMBA). Body length 2.8 mm. Body reddish brown, elytra unicolorous, legs and antennae slightly paler.

Antero-lateral margins of frons simple. Gular rugules of different sizes, anteriorly larger somewhat ordered. Clypeal granules minute but distinct. Setation of head very short and fine, appressed medially on vertex, distinctly coarser around eyes and ventro-laterally. Antennae moderately long; antennomeres III–V nearly 1.9 as long as wide, X slightly transverse, 0.9 times as long as wide; setation mostly fine, rather coarse to scaly on basal 3–4 antennomeres.

Pronotum 1.8 times as long as wide, its lateral margins somewhat unevenly shaped, rather rounded at widest point and nearly straightly narrowing towards base in dorsal view; posterior collar narrow but distinct. Pronotal horn robust, moderately wide, its posterior angles obsolete in dorsal view ( Fig. 155 View Figs 150–158 ); horn margins armed with five, comparatively small (narrow) lobules on each side, apical lobule bilobed, dorsal side evenly vaulted and covered by rugules, horn crest at most slightly indicated. Setation whitish, mostly scaly; scales on pronotal disc of two lengths, shorter and appressed or longer and subdecumbent, both truncate apically; erect tactile setae absent; antebasal paired setae rather long and conspicuous laterally, absent medially.

Elytra nearly 1.7 times as long as wide; omoplates and postbasal impression absent. Setation whitish and reddish, forming rather vague, transverse spot at mid-length ( Fig. 200 View Figs 194–201 ), uniformly short and appressed, scaly, evenly ordered; scales rather elongate, nearly linear, rounded apically, densely spaced but distinct (surface visible); erect tactile setae absent.

Male characters. Sternum VII moderately produced and slightly emarginate apically. Tergum VIII and aedeagus as in Figs 72, 73 View Figs 67–73. 67–68 .

Variation. Body length (♂ ♀) 2.3–3.0 mm. Pronotal horn with 4–5 lobules on each side; apical lobule sometimes nearly simple, widely rounded, with slight median incision. Reddish transverse spot on elytra distinct to vaguely indicated.

Differential diagnosis. Mecynotarsus leai   displays a rather distinctive morphology of the pronotal horn (indistinct crest, evenly scattered rugules). In addition, it can be easily recognized by the male characters, mainly by the tegmen being strongly narrowed apically, and by the somewhat sinuous, apically narrowed, simply rounded to subtruncate parameres.

Distribution. Australia: New South Wales ( LEA 1922), Victoria (new record), Tasmania ( LEA 1922).

The records of M. maculatus   from Queensland and South Australia ( LEA 1922) refer to misidentified specimens of M. albellus   .
