Type material studied. Holotype: AUSTRALIA: ♂: three labels: " 42.08 S 147.54 E TAS / Big Sassy  Creek, 400m / 17 May 1989 Site 1 / rotten log, Tube 252 / J. Diggle" [white, printed], " ANIC / Specimen" [green, printed], " Spinosciacharis  / sassy  m. / det. P. Jałoszyński, 2014 / HOLOTYPUS " [red, printed] ( ANIC). Paratypes: 2 ♀♀, same data as for the holotype, with standard yellow " PARATYPUS " label ( ANIC, cPJ).

Diagnosis. Male and female: BL 2.00– 2.10 mm; elytra oval; EI> 1.5. Male: metafemur with slightly curved and pointed ventral projection, with distinct distal ventral lobe.

Description. Body of male ( Fig. 114View FIGURES 112 – 116) flattened, elongate and slender, with long appendages, BL 2.10 mm; cuticle glossy, body light brown, with slightly lighter appendages, vestiture yellowish.

Head ( Fig. 114View FIGURES 112 – 116) rounded, broadest just behind eyes, HL 0.38 mm, HW 0.50 mm; tempora nearly three times as long as eyes, strongly curved posteromesally; vertex evenly convex; frons confluent with vertex, subtrapezoidal, convex. Eyes small and weakly protruding laterally from the head silhouette, finely faceted. Punctures on head dorsum inconspicuous, fine and sparse, not larger than those on pronotum; setae on frons and median part of vertex short, sparse and suberect, tempora and sides of vertex with moderately dense bristles directed posterolaterally. Antennae ( Fig. 114View FIGURES 112 – 116) slender, AnL 1.00 mm; antennomeres I –VI distinctly elongate, VII only slightly longer than broad, VIII –X slightly transverse; XI much shorter than IX –X together, 1.8 x as long as broad, pointed.

Pronotum ( Fig. 114View FIGURES 112 – 116) in dorsal view elongate, broadest near anterior third, PL 0.55 mm, PW 0.50 mm; anterior and lateral margins rounded; posterior margin distinctly bisinuate; base of pronotum with distinct but short sublateral carinae accompanied mesally by relatively deep impressions, median portion of pronotal base with two small but deep pits separated by narrow carina as long as two diameters of pit and only posteriorly extending beyond pits to reach posterior pronotal margin. Punctures on pronotal disc fine and inconspicuous, similar to those on frons and vertex; setae sparse, thin, short and suberect, only sides of pronotum with moderately dense bristles.

Elytra ( Fig. 114View FIGURES 112 – 116) slightly rhomboidal, broadest distinctly anterior to middle, EL 1.18 mm, EW 0.78 mm, EI 1.52; basal impressions short but deep; circumsutural area in anterior fourth distinctly more convex than surrounding surface and accentuated posteriorly by distinct transverse impression; elytral apices rounded together. Punctures on elytral disc fine but slightly more distinct and denser than those on pronotum; setae short, sparse and suberect. Hind wings well developed, about twice as long as elytra.

Legs ( Figs. 114View FIGURES 112 – 116, 118View FIGURES 117 – 120) long and slender, metafemur ( Fig. 118View FIGURES 117 – 120) with long, pointed and slightly curved ventral projection femur, with distinct ventral distal lobe.

Aedeagus ( Figs. 123–124View FIGURES 121 – 128) elongate, AeL 0.35 mm, in ventral view sides of median lobe rounded, apical margin broadly rounded; internal armature in the only known male partly everted, lightly sclerotized, with one pair of lateral apical microdenticulate structures and two sublateral lobes, each with distinct external projection, median part of everted armature occupied by long subtriangular projection protruding distally; parameres not broadening distally and their apices only slightly exceeding apex of median lobe.

Female. Similar to male, differs in unmodified metafemora and more slender elytra; BL 2.00– 2.08 mm; HL 0.40 mm, HW 0.48 mm, AnL 0.95 mm; PL 0.50 mm, PW 0.45–0.49 mm; EL 1.10-1.18 mm, EW 0.68–0.73 mm, EI 1.62–1.63.

Etymology. Locotypical, after the Big Sassy  Creek.

Distribution ( Fig. 196View FIGURES 193 – 198 b). South-eastern Australia: Tasmania.

Remarks. Spinosciacharis sassy  has the metafemoral projections similar to those of Spinosciacharis puncticeps  , but it is smaller and lightly pigmented. Moreover, among all species, Spinosciacharis sassy  has the shortest and broadest pronotum in relation to the head.
