Description (holotype, male). Body length 1.8 mm. Head and pronotum reddish brown, head vertex darker, nearly brown black, elytra reddish, with vague darker markings; legs and antennae reddish.
Antero-lateral margins of frons simple. Gular rugules of different sizes, anteriorly larger, ordered and fused as in Fig. 139. Clypeal granules indistinct. Setation of head uniformly short and appressed, finer medially on vertex, distinctly coarser to scaly around eyes and ventrolaterally. Antennae rather moderately long; antennomeres III–V 1.7 times, X 1.2 times as long as wide; setation mostly fine, distinctly coarser to scaly on basal 2–3 antennomeres.
Pronotum moderately transverse, 1.4 times as long as wide, its lateral margins somewhat unevenly shaped in dorsal view, slightly angled at widest point and nearly straight in narrowing towards base in dorsal view; posterior collar narrow but distinct. Pronotal horn robust and wide, its posterior angles indicated in dorsal view (Fig. 161); horn margins armed with 4 lobules on each side, apical lobule distinctly bilobed; horn crest very distinct, raised, with coarse rugules on margins; submarginal rugules rather coarse and distinctly spaced; median rugules largely fused and forming longitudinal sculpture, with single minute granule posteriorly. Setation whitish, with slight reddish tinge dorsally, largely scaly, appressed to subdecumbent, distinctly finer, hairy dorsally on pronotal horn (even here rather distinct and dense); scales on pronotal disc of two sizes, larger scales more raised and distinctly truncate apically; antebasal paired setae present laterally and absent medially, another tactile setae absent.
Elytra 1.8 times as long as wide; omoplates and postbasal impression absent. Setation brownish and whitish, mixed and forming also rather vague brownish markings (Fig. 205), scaly and appressed, evenly ordered; scales elongate, rounded to subtruncate apically, densely spaced (surface barely visible, Fig. 180); erect tactile setae absent.
Male characters. Sternum VII simple. Tergum VIII and aedeagus as in Figs 86, 87.
Variation. Body length (♂ ♀) 1.8–2.1 mm. Pronotal horn with 4–5 lobules on each side. Body colouration reddish to dark brown.
Differential diagnosis. Mecynotarsus parvulus sp. nov. can be easily recognized by combination of the following external characters: small body size; elytra rather elongate, subparallel; pronotal horn distinctly, rather finely and densely setose dorsally, apical lobule bilobed, single longitudinal median rugule; elytral scales rather contrastingly bicoloured, evenly mixed in basal half (Fig. 180). Moreover, the presence of a small tuft of setae on the parameres (Fig. 87) is a quite distinctive character, unique within M. ziczac species-group.
Etymology. The species name is a Latin adjective, parvulus, -a, -um (= little, slight); named in reference to the small body size.
Distribution. Australia: Northern Territory, Queensland.
