( Figs 110 , 111 , 166 , 184 ) Type locality. Australia , Western Australia , Drysdale River, 15°02′S 126°55′E . Type material. HOLOTYPE : ♂ , ‘ 15.02S 126.55E Drysdale River, W.A. 3–8Aug. 1975 I.F.B.Common and M.S. Upton [p] // ANIC Specimen [p; green label]’ ( ANIC ). Description ( holotype , male). Body length 2.6 mm . Body, legs, and antennae reddish to reddish brown. Antero-lateral margins of frons distinctly raised (angulately lobed) near insertion of antennae. Gular rugules coarser anteriorly and here ordered as in Fig. 138 . Clypeal granules rather distinct. Setation of head mostly fine and appressed, with numerous very long, more or less raised setae on vertex. Antennae moderately long; antennomere II about as long as III, antennomeres III–V 1.8–1.9 times as long as wide, X nearly 1.2 times as long as wide; basal 4–5 antennomeres with longer and coarser setation (not scaly). Pronotum 1.6 times as long as wide, its lateral margins somewhat unevenly convex in dorsal view; posterior collar distinct; surface of pronotal disc, including dorso-lateral sides, with numerous scattered granules ( Fig. 166 ). Pronotal horn rather robust, moderately wide, subtriangular, its posterior angles moderately indicated in dorsal view ( Fig. 166 ); horn margins armed with 3 or 4 rather long, apically rounded lobules on each side, apical lobule simple, broadly rounded; horn crest distinct, rather wide, with coarse, separate rugules on margins; submarginal rugules numerous, somewhat unevenly spaced; 5 median rugules rather coarse and well-spaced. Setation whitish to silvery, appressed and very dense, sparser to absent antero-dorsally on pronotal horn, with numerous long erect setae; appressed setae on pronotal disc bifurcate to somewhat frayed apically, very dense laterally, here nearly felt-like, entirely covering surface; antebasal paired setae probably present probably both laterally and medially, but difficult to recognize owing to presence of many additional tactile setae. Elytra 1.6 times as long as wide; omoplates and postbasal impression absent. Setation scaly, whitish to silvery and reddish, forming vague reddish markings; scales appressed and rather long, bifurcate to frayed apically, densely and evenly spaced, nearly entirely covering surface ( Fig. 184 ); erect tactile setae very numerous, moderately long and evenly scattered, including apical portion of elytra. Male characters. Sternum VII moderately sinuous posteriorly. Tergum VIII and aedeagus as in Figs 110 , 111 . Figs 111–118. 111 – Mecynotarsus speciosus sp.nov. , aedeagus in dorsal view. 112–115 – M. weiri sp.nov. :112 – sternum VII, 113 – tergum VIII, 114 – aedeagus in dorsal view, 115 – the same, lateral view. 116–118 – M. ziczac King, 1869: 116 – tergum VIII, 117 – aedeagus in dorsal view, 118 – the same, lateral view. Scale (0.5 mm): A – Figs 111, 116; B – Figs 112, 113; C – Figs 114, 117, 118. Differential diagnosis. Mecynotarsus speciosus sp. nov. can be easily distinguished from all species by the setation characters of the body: pronotal disc and elytra densely covered by silvery, bifurcate to frayed setae ( Fig. 184 ), and hirsute, with many erect tactile setae. Additionally, it is conspicuous in having a granulate pronotum, comparatively short antennae (most species with a granulate pronotum have conspicuously long antennae), distinctly lobed lateral margins of the frons, and a rather distinctive form of the parameres. Etymology. The species name is a Latin adjective, speciosus , -a, -um (= beautiful, splendid); named in reference to the unique body setation. Distribution. Australia : Western Australia .
