description: Scydmaenozila mallacootana sp. n.
(Figs. 74, 85–86, 93–94, 195 c)
Type material studied. Holotype: AUSTRALIA: ♂: four labels: " AUSTRALIA / Victoria / Mallacoota N.P. / 26 May 1978 / S. & J. Peck" [white, printed], "mushroom / litter' [white, printed], "Aust. Nat. / Ins. Coll." [green, printed], " SCYDMAENOZILA / mallacootana m. / det. P. Jałoszyński, 2014 / HOLOTYPUS " [red, printed] (ANIC).
Diagnosis. Male and female: body uniformly brown. Male: aedeagus slender, in ventral view with broadly rounded apex; apical part of median lobe abruptly demarcated.
Description. Body of male (Fig. 74) strongly convex, elongate and slender, with long appendages, BL 2.75 mm; cuticle glossy, dark brown with reddish hue, elytra slightly lighter than head and pronotum, vestiture dark brown.
Head (Fig. 74) broadest at eyes, HL 0.50 mm, HW 0.60 mm; tempora longer than eyes, strongly curved posteromesally; vertex weakly convex; frons subtrapezoidal. Eyes large and strongly projecting laterally from the head silhouette, finely faceted. Punctures on head dorsum fine, separated by spaces 1.5– 2 x as wide as diameters of punctures; setae on frons and anterior portion of vertex short, sparse and suberect, tempora and posterior portion of vertex densely covered with long bristles directed posteriorly and posterolaterally. Antennae (Fig. 74) slender, AnL 1.65; antennomeres I–VII distinctly elongate, VIII slightly longer than wide, IX–X each about as long as broad, XI as long as IX–X together, 2.5x as long as broad, pointed.
Pronotum (Fig. 74) in dorsal view strongly elongate, broadest near anterior third, PL 0.80 mm, PW 0.63 mm; anterior and lateral margins in anterior half rounded; sides slightly concave in posterior third; posterior margin distinctly bisinuate; base of pronotum with two pairs of large and deep pits, additionally with a pair of shallow but distinct impressions located dorsolaterally. Punctures on pronotal disc fine and inconspicuous; entire dorsal and lateral surface of pronotum covered with moderately dense bristles, dorsally with admixture of thin setae.
Elytra (Fig. 74) slightly rhomboidal, broadest near middle, EL 1.45 mm, EW 1.05 mm, EI 1.38; basal impressions short but distinct; elytral apices separately rounded. Punctures on elytral disc fine but slightly more distinct than those on pronotum, separated by spaces 2– 3 x as wide as diameters of punctures; setae long, curved, sparse and erect. Hind wings well developed, about twice as long as elytra.
Legs (Fig. 74) long and slender, without modifications.
Aedeagus (Figs. 85–86, 93–94) elongate and relatively slender; AeL 0.63 mm; in ventral view short apical part abruptly demarcated, with broadly and weakly rounded apical margin; in lateral view apical part subtriangular and sharply demarcated from ventral wall; internal armature complicated, with submedian complex of elongate and darkly sclerotized structures and subapical finely denticulate lateral lobes of internal sac; parameres long and slender, with distinctly broadened apices.
Female. Unknown.
Distribution (Fig. 195 c). South-eastern Australia: Victoria.
Etymology. Locotypical, after the Mallacoota National Park, where this species occurs.
Remarks. Scydmaenozila mallacootana has the aedeagus very similar to that of Scydmaenozila macrosticta; differences can be seen only in the arrangement of internal structures. However, externally these species are distinctly different: Scydmaenozila macrosticta has the bicolorous pattern on elytra, while Scydmaenozila mallacootana is uniformly brown; also the shape of the pronotum and elytra is different (Fig. 72 vs. 74).
